Pilot explains why plane windows are rounded

<p dir="ltr">A pilot has revealed why plane windows are the unique shape that we see today, sharing a glimpse into the world of airplane design and engineering. </p> <p dir="ltr">American Airlines pilot Captain Steve, who regularly makes TikTok videos on the marvel of flying, shared the reason why plane windows today are slightly rounded instead of square, revealing why this design became the norm. </p> <p dir="ltr">"Some of the airliners were designed with square windows and over in Europe as airplanes started to climb higher and require more pressurisation, they discovered a problem," he shared in a clip that has since been viewed over two million times.</p> <p dir="ltr">Following a series of inflight disasters caused by their rectangular counterparts, the window designs had to be changed, as Captain Steve said, “The airplanes literally came apart.”</p> <p dir="ltr">He added that "they lost a few airplanes in midair" because the square windows created "a hairline crack" right in the edge, and the stress on the airframe caused by the pressurisation was simply too much.</p> <p dir="ltr">As a result, engineers decided to round the windows' frames so they wouldn't break under the strain and they've "never had a problem since," according to the pilot.</p> <p dir="ltr">The video was flooded with comments by curious passengers, with one person writing, “I have never thought about this but it makes so much sense! Captain Steve is teaching us yet again.”</p> <p dir="ltr"><em>Image credits: Shutterstock </em></p>

Victorian plane crash victims identified

<p>Three young men have been killed after a light plane crash in eastern Victoria at around 5.45pm on Saturday. </p> <p>Pilot Luke Smith, 20, his younger brother Ben Smith, 16, and their cousin Dustin Daly, 15, were on board the plane when it crashed into a paddock and burst into flames at Tinamba West in east Gippsland. </p> <p>They were only 15 minutes into the flight, which took off from West Sale airport, when the tragic incident occurred. </p> <p>The plane was reportedly seen circling several times, with witnesses saying they heard a strange sound coming from the aircraft in the moments before the crash. </p> <p>“From accounts that I’ve seen, there may have been circling or manoeuvring to resolve that issue or to try to find somewhere to land and unfortunately, that has happened,” Aviation Projects managing director Keith Tonkin said.</p> <p>Luke Smith has held a pilot licence since 2022 and was also an instructor. His aviation consultant and flying instructor Lorraine MacGillivray has paid tribute to the three young men. </p> <p>“They were all absolutely delightful human beings, and so this is a terrible loss,” MacGillivray said.</p> <p>“The conversations I had with him, he was diligent and he was committed and he was passionate about his flying,” MacGillivray said.</p> <p>“He was also a flight instructor.”</p> <p>The brothers were also heavily involved in the Tongala football and cricket clubs, who have since offered counselling to the grieving regional community. </p> <p>The Australian Transport Safety Bureau (ATSB) is investigating the crash, with a team of investigators specialising aircraft operations and maintenance looking into what happened. </p> <p>The ATSB described the plane as "amateur-built light aircraft" and will examine the wreckage, interview witnesses and comb through flight tracking data to try and determine what went wrong. </p> <p>“We’ll start looking at the records of the plane itself, and maintenance records and pilot qualifications and the actual tasking or the nature of the flight itself,” ATSB Chief Commissioner Angus Mitchell said.</p> <p>Witnesses who saw the incident or anyone who has photos or videos of the plane have been asked to come forward. </p> <p><em>Images: 7News</em></p>

Why planes still have no smoking signs

<p dir="ltr">Have you ever wondered why planes still have dozens of no smoking signs inside an aircraft, even 30 years after a worldwide ban was implemented?</p> <p dir="ltr">A travel expert has answered this age-old question, just weeks after the US Federal Aviation Administration (FAA) got rid of the off switch for no smoking signs.</p> <p dir="ltr">This means that for all American planes across every US airline, the no smoking signs stay lit throughout the entire time you’re on board, which includes taxing, takeoff, cruising and landing.</p> <p dir="ltr">While it would seem that no smoking signs onboard planes are no longer needed nowadays, they are actually very much needed.</p> <p dir="ltr">“While no smoking signs may seem like an old and outdated practice, they are still a necessity for a few different reasons,” RVshare travel expert Maddi Bourgerie told <a href="https://www.thrillist.com/news/nation/planes-no-smoking-signs-why-expert"><em>Thrillist</em>.</a></p> <p dir="ltr">Firstly, it’s down to public health and safety, as Ms Bourgerie said, “There are aviation regulations in place that require airlines to maintain a no-smoking policy, which is largely due to the flammability of materials in the cabin.”</p> <p dir="ltr">She added, “the signs reinforce a smoke-free environment for all passengers and crew,” with second-hand smoke being dangerous to those around you in an enclosed space.</p> <p dir="ltr">Ms Bourgerie also explained that having the signs gives the airline some protection from potential lawsuits, with the signs acting as a safety net if a smoking-related incident occurs on board.</p> <p dir="ltr">The travel expert also pointed to a less obvious reason for keeping the no smoking signs, explaining, “Many procedures and protocols in aviation are maintained for consistency and familiarity.”</p> <p dir="ltr">“And the no smoking sign has become a standard part of the in-flight experience.”</p> <p dir="ltr"><em>Image credits: Shutterstock</em></p>

Baggage handler reveals the best kind of luggage to travel with

<p dir="ltr">A baggage handler has revealed the best kind of suitcase you should travel with when travelling by plane.</p> <p dir="ltr">With years of experience loading planes with thousands of kinds of suitcases, a ramp agent for American Airlines has spilled the secrets on why some kinds of luggage are better than others. </p> <p dir="ltr">The worker said that while many people may gravitate towards hard-shell suitcases for extra protection, they are not the best for air travel. </p> <p dir="ltr">"Avoid plastic hard shell suitcases," the airline worker revealed on Reddit. "These are incredibly slick and prone to sliding off the bag cart while turning - taking everything on top of it with it."</p> <p dir="ltr">Instead, cloth suitcases have more friction and are "more likely to stay where we put them."</p> <p dir="ltr">He also said these days, four wheels on a suitcase is an absolute must as opposed to ones that glide on just two wheels.</p> <p dir="ltr">"If your bag has four wheels, it can simply be rolled along the floor. If it does not, it will be thrown. We don't try to slam it into anything, but it's still going to drop about 2ft (6m) over the course of its 'flight'," the crew member shared.</p> <p dir="ltr">Another thing to consider when buying your next suitcase is finding one that has handles on the side as it gives baggage handlers "far more control" over the luggage.</p> <p dir="ltr">"It's easier to get a grip with an actual handle than by grabbing a wheel," he added.</p> <p dir="ltr">The worker also said using a big bag for no reason is only going to cause the bag to collapse once it is stacked and cause a "baggage avalanche", with the same going for bags that are not "normally shaped" suitcases.</p> <p dir="ltr"><em>Image credits: Shutterstock</em></p></p>

Drunk couple forces emergency landing after mid-air meltdown

<p>A Ryanair flight to Ibiza had to be diverted after a drunk couple allegedly assaulted cabin crew and other passengers. </p> <p>The plane, carrying holiday-makers from Manchester to Ibiza had to make an emergency landing in Toulouse, where police hauled the intoxicated passengers off the plane. </p> <p>A British traveller on the flight, who asked to remain anonymous, recalled the man "swigging duty free vodka" on the first hour of the flight, before he started arguing with a male cabin crew member and punched him in the face. </p> <p>As they tried to restrain him, the intoxicated man assaulted another passenger and spat at a woman, hurling verbal abuse at her. </p> <p>“He was kicking off with everyone, he was out of control,” the witness said.</p> <p>Flight attendants reportedly warned him that the flight would have to be diverted if he didn't calm down, but he replied: “I don’t give a f***.” </p> <p>The altercation lasted for about 40 minutes until Flight FR2626 had to land in Toulouse, and 12 police officers took him away in custody. </p> <p>Video of the attack showed the man shouting and swearing at the police, before assaulting another traveller as he was being escorted off the flight. </p> <p>After he left the plane, his partner started harassing another traveller, hitting him and calling him a "paedo". </p> <p>In another video, police were filmed physically restraining the woman, before removing her from the plane. </p> <p>The flight spent just over an hour and a half on the tarmac at the Toulouse-Blagnac Airport before continuing its journey to Ibiza.</p> <p>Just last week Ryanair chief executive Michael O’Leary called for flyers to be limited to two drinks at airports to crack down on disorderly behaviour on flights. </p> <p>“We don’t want to begrudge people having a drink," he said. </p> <p>“But we don’t allow people to drink-drive, yet we keep putting them up in aircraft at 33,000ft.</p> <p>“In the old days, people who drank too much would eventually fall over or fall asleep. But now those passengers are also on tablets and powder.</p> <p>“It’s the mix. You get much more aggressive behaviour that becomes very difficult to manage.”</p> <p>The airline has started carrying out hand luggage checks to stop passengers on flights to Ibiza and the Greek islands from smuggling duty-free alcohol on-board. </p> <p>A Ryanair spokesperson has apologised for the incident saying:  “This flight from Manchester to Ibiza diverted to Toulouse after a small group of passengers became disruptive in-flight." </p> <p>“The crew called ahead for police assistance, who met the aircraft upon landing at Toulouse and offloaded two passengers before this flight continued to Ibiza.</p> <p>“We sincerely apologise to passengers for any inconvenience caused as a result of these unruly passengers’ behaviour, which was beyond Ryanair’s control. This is now a matter for local police.”</p> <p><em>Image: news.com.au</em></p>

Strangers lock toddler in plane bathroom to stop her tantrums

<p>The video of a controversial incident on a plane has caused outrage, as two women reprimanded a screaming toddler by locking her in the bathroom on the aircraft. </p> <p>On a Juneyao Airlines flight from Guiyang to Shanghai, China, in late August, a one-year-old child, who was travelling with her grandparents, reportedly sobbed non-stop during the nearly three-hour flight according to the <a href="https://nypost.com/2024/08/30/lifestyle/strangers-lock-crying-tot-in-airplane-bathroom-to-educate-her/" target="_blank" rel="noopener"><em>NY Post</em></a>. </p> <p>After being fed up with the toddler's tantrum, two women who were strangers to the family reportedly transported her to the bathroom to “educate her.”</p> <p>Shockingly, the child’s grandmother consented to the treatment.</p> <p>The punitive pair then shared the video of this alleged “potty training” on Douyin, China’s version of TikTok.</p> <p>In the clip, the women can be seen seated in the locked lavatory with the screaming infant, as one of the women is heard saying, “If you stop crying, aunty will take you back to grandma” and “We won’t let you out unless you stop crying.”</p> <p>As the girl stopped crying, the woman filming the video picked her up and told her: “If you make any noise again, we’ll come back (to the bathroom).”</p> <p>One of the women was initially proud of her cruel and unusual-seeming form of discipline, as she wrote that the tantrum was so disruptive that “many passengers were using tissues to block their ears” while others “had moved to the back of the plane to escape the noise.”</p> <p>According to a statement from the airline, the little girl's mother, who was not travelling with them, reportedly sympathised with the self-appointed aeroplane posse’s behaviour.</p> <p>Since the video went viral, and was subsequently deleted, Juneyao Airlines’ reps have since condemned the pairs’ actions and apologised for the incident and “oversight of the crew”.</p> <p>Despite the video being wiped from the social media site, many were quick to slam the behaviour of the women, saying their discipline was completely unacceptable. </p> <p>“Adults in their 30s can have emotional breakdowns, but people don’t allow toddlers to have theirs,” one person commented, </p> <p>Another wrote, “The grandmother and the two aunts should be sued, and social services should intervene. If there are parents like this, children will suffer in the future.”</p> <p>“When will these people understand that babies have the right to cry and the right to travel, they are part of society, and so are babies!!!!!!!” declared a third.</p> <p><em>Image credits: Weibo</em></p>

Passenger sparks debate over travellers sleeping in aisle seats

<p>A heated debate has erupted online after a passenger suggested those sitting in an aisle seat should remain alert and awake for the entire flight, with the only exception being if it's a long-flight of seven hours or more. </p> <p>“A person sitting in an aisle seat on a plane should not be allowed to sleep," they wrote on Reddit. </p> <p>The reason behind it, according to the passenger, is to ensure that middle and window seat passengers can access the toilet, get served by flight attendants, and evacuate quickly in an emergency. </p> <p>“There are some exceptions and those would probably be on any flight longer than seven hours.</p> <p>“But anything shorter than that, you should not be sleeping. What if the middle or window passenger needs the bathroom, or if the flight attendant needs to hand them something – You’ll be in the way.”</p> <p>They added that a snoozing aisle seat passenger could potentially slow down evacuation during an emergency and put everyone at risk. </p> <p>“Now you would be risking people’s lives because you fell asleep,” they wrote.</p> <p>Social media users flocked to the Reddit thread to share their thoughts. </p> <p> “Nah, just poke me and wake me up if you need me to get up or do something," one wrote. </p> <p>“I’m well aware that I’m in the way, believe me. I’m certainly not there because I wanted to be in the aisle seat.”</p> <p>“If you sleep in an aisle seat, you deal with people getting up. That’s the unwritten rule," another added. </p> <p>A few others supported the idea, but shared their own take on plane etiquette. </p> <p> “My take on this: if you sleep in the aisle seat, you must be okay with being woken up multiple times to let the folks in your row get up.</p> <p>“Other flight rules: middle seat gets the armrest, and window seat must raise the window shade during taxi, takeoff, and landing so the rest of us in the row can watch.”</p> <p><em>Image: Shutterstock</em></p> <p> </p>

Young Aussie medallist's sweet plane gesture

<p>Australian gold medallist Arisa Trew has warmed hearts after sharing her sweet gesture on the plane back from Paris. </p> <p>Trew became the youngest Australian to ever win a gold medal at the Paris games after emerging victorious in the skateboarding competition, capturing the hearts of Australia with her incredible performance. </p> <p>Trew was one of dozens of Aussies who <a href="https://oversixty.com.au/travel/international-travel/just-magical-aussie-olympians-return-home-in-triumph" target="_blank" rel="noopener">flew back</a> from Paris on Wednesday morning, and explained why she was quick to give up her business class seat as a medallist. </p> <p><em>Sunrise</em> host Matt Shirvington said there was a pecking order to the seat allocation on the Qantas plane, explaining, “Apparently, the breakdown is the medallists get first pick of business class, then the two-time Olympians or more get a shot at premium economy, and the rest are out the back of the plane.”</p> <p>By winning gold, Trew was allowed to be in the expensive business class seats, but she told the Jase & Lauren radio show on Nova radio that she had other plans for the lengthy flight.</p> <p>“Where did you get to sit on the plane? Because you’re a gold medallist, you’re 14 years old. Were you right up the front?” Lauren Phillips asked Trew.</p> <p>Trew’s reply stunned the radio hosts, as she admitted, “I mean, I could have been sitting in business with all the medallists, but instead I chose to sit in economy with my two best friends, Chloe and Ruby.”</p> <p>Those friends are fellow skateboarders Chloe Covell and Ruby Trew who both missed out on medals, hence their seats “out the back”.</p> <p>“You’re the cutest thing ever. We couldn’t love you anymore,” Phillips said.</p> <p>“So Arisa, does that mean you got to give someone your gold medal business class seat?”</p> <p>Trew replied, “I’m pretty sure somebody else got it because me and my friends were walking around the plane, and we went up there, and it was all full. So I definitely think somebody else was sitting there but I don’t mind.”</p> <p>Trew also revealed she was heading straight back to school after touching down in Australia and would be there bright and early on Thursday.</p> <p>“I’m gonna go back. I just love going to school, because it’s the skate park where I go to school,” she said.</p> <p>“So I get to see all my friends that skate, that I skate with every day and train with, my coaches, the teachers. Like, it’s just the best thing in the world.”</p> <p><em>Image credits: Ulrik Pedersen/CSM/Shutterstock Editorial </em></p>

Woman “bullied” on plane over budget seating trick

<p dir="ltr">A young woman has recalled a flight from hell when she was “bullied” by a couple who were trying to utilise a seating hack that went viral on TikTok. </p> <p dir="ltr">The solo traveller took to Reddit to recount the story and ask social media users if she was in the wrong for her action. </p> <p dir="ltr">The woman began by saying she usually pays more to select her plane seat ahead of time, but a medical emergency on another plane had her waiting on standby and left with no option other than to sit in a middle seat.</p> <p dir="ltr">When she was finally able to board, she was greeted by a couple who had purchased both the window and aisle seats in a bid to have more space, utilising a travel “trick” that has been popular on TikTok.</p> <p dir="ltr">The method, which has been dubbed the 'poor man's business class', usually leaves travellers with an empty middle seat and more space, and few travellers opt to pick a middle seat. </p> <p dir="ltr">“When I got to my row the man and woman were chatting and sharing a snack... it was obvious they were together. I mentioned to the man that I'm in the middle, and he got up to let me in,” the unsuspecting traveller wrote on Reddit.  </p> <p dir="ltr">“I asked them if they would prefer to sit together, I said I was totally okay with that. The woman reacted rudely to this and said ‘you're not supposed to be sitting here anyway’.”</p> <p dir="ltr">After noticing how the plane was full, she offered to show the pair her new ticket with the correct seat number on it.</p> <p dir="ltr">“She flicked her hand at my ticket and made a disgusted sound. I offered again if they wanted to sit together to which she didn't reply, her partner said it's okay and... made some small talk,” she continued. </p> <p dir="ltr">The man’s girlfriend then interrupted their conversation to ask,”'Did you use one of those third party websites to book your flight? It's so frustrating when people cheap out to inconvenience others.”</p> <p dir="ltr">The American woman explained that she had booked her flight directly and she had been placed on standby like everyone else and didn't choose the middle seat - she was assigned it.</p> <p dir="ltr">She then tried to keep the peace by refusing to engage with the furious woman.  </p> <p dir="ltr">“I was so done with her attitude, I put my headphones on and attempted to do my own thing,” she explained.</p> <p dir="ltr">But the “entitled” girlfriend wasn't letting it go, as the woman explained, “This woman kept reaching over me and tapping her partner and trying to talk to him in a way that was super intrusive.”</p> <p dir="ltr">“I could tell even her partner was trying to engage her less so that she would hopefully stop, but she didn't.”</p> <p dir="ltr">“I think they tried to pull that tactic where they don't sit together on purpose...hoping no one will sit between them. But on full flights it doesn't work. And even so - it's not the other person's fault.”</p> <p dir="ltr">The traveller's post was met with hundreds of comments slamming the girlfriend’s behaviour, as one person wrote, “It's like a toddler having a tantrum.”</p> <p dir="ltr">“She was disappointed and a total a**hole. Gross entitled people,” another added. </p> <p dir="ltr">Another person applauded the traveller’s level-headed behaviour, writing, “Wow! You are my hero for keeping it classy - I’m afraid I would not have been as kind as you.”</p> <p dir="ltr"><em>Image credits: Shutterstock </em></p>

“Great initiative”: Airline's world first move to make female travellers safer

<p>A popular airline has introduced a new measure to help female travellers feel safer on their journey. </p> <p>IndiGo will make the change in August, giving female travellers the option to choose not to sit next to a man on their flight. </p> <p>Prior to booking, women will be able to check the gender of the flyer sitting next to them and select if they don't want a male seat mate. </p> <p>However, this change will not apply to men, as male travellers will not be shown the gender of their seat mate when making a booking and instead will only be able to view available seats.</p> <p>The low-cost carrier is a codeshare partner of Qantas, and Australian passengers travel on-board its planes for destinations such as India, as well as within the country. </p> <p>The idea for the change came from an IndiGo survey where the airline asked females what would make travel more comfortable, and many said they would feel safer to have more power over who they spent their journey sitting next to. </p> <p>“IndiGo is proud to announce the introduction of a new feature that aims to make the travel experience more comfortable for our female passengers,” the airline said.</p> <p>“We are committed to providing an unparalleled travel experience for all our passengers, and this new feature is just one of the many steps we are taking towards achieving that goal.”</p> <p>There has been a mixed reaction on social media to to IndiGo’s attempt to make female flyers feel safer, as one commenter wrote on X: “Why can’t they allocate left side for one gender and right side for another gender?"</p> <p>There was also concern about how the good seats could be snapped up, writing, “Almost all seats available will be the middle ones”.</p> <p>Meanwhile a man protested, “What if I don’t want to sit by her? It works both ways”, while many simply praised it as a “great initiative”.</p> <p><em>Image credits: Shutterstock </em></p>

The surprising reason commercial planes are painted white

<p dir="ltr">Up until the middle of the last century, airplanes would fly through the sky unpainted as shiny silver tubes. </p> <p dir="ltr">But now, we are so used to seeing plane bodies being painted white, with the exception of the airline’s logo and a splash of colour on the plane’s tail. </p> <p dir="ltr">But this drastic look isn’t just about style and uniformity, as there is a simple reason why plane bodies are left plain. </p> <p dir="ltr">First of all, white paint jobs will show wear and tear a lot quicker on huge commercial planes and while this might not be ideal for a car or house, it's perfect for planes.</p> <p dir="ltr">From takeoff to landing, a plane goes through a lot. While the aircrafts are always deemed safe for flying, it'll likely suffer minor cosmetic damages as it hurtles through the sky at 900 kilometres per hour.</p> <p dir="ltr">Due to the frequent minor chips and scratches a plane has inflicted, using the white paint helps engineers and maintenance teams to spot any of these issues with ease. </p> <p dir="ltr">Another reason that white is uniform in the skies is because white paint is going to fade at a much slower rate than a darker shade. </p> <p dir="ltr">As planes fly above the clouds, they're exposed to a lot of UV rays which speeds up the process of the paint fading.</p> <p dir="ltr">Lastly, it's been found that birds can spot planes against the sky easier when they're painted all-white, as sometimes in rare occasions, birds can pose a safety risk.</p> <p dir="ltr">It wasn’t until 50 years ago that airlines started painting their planes, with Air France being credited for starting the movement in the 1970s. </p> <p dir="ltr">"Since Air France introduced the first 'Euro-white' livery in 1976, the all-white fuselage look has become increasingly standard for the world's airlines," aviation historian Shea Oakley told Travel + Leisure. </p> <p dir="ltr"><em>Image credits: Shutterstock </em></p>

It can damage planes, and even lead to deaths.</p> <h2>How common are bird strikes?</h2> <p>A bird strike is a <a href="https://skyaviationholdings.com/bird-strikes-on-planes/">collision between</a> an aircraft and a bird. (Though the definition is sometimes expanded to include <a href="https://aawhg.org/">collisions on the ground</a> with land animals including deer, rabbits, dogs and alligators.)</p> <p>The <a href="https://digitalcommons.unl.edu/icwdm_usdanwrc/1459/">first bird strike</a> was recorded by Orville Wright in 1905, over a cornfield in Ohio.</p> <p>Now they happen every day, with some seasonal variability due to the <a href="https://www.faa.gov/air_traffic/publications/atpubs/aim_html/chap7_section_5.html">migratory patterns</a> of birds.</p> <p>Perhaps the most famous migratory bird strike occurred in 2009, when <a href="https://en.wikipedia.org/wiki/US_Airways_Flight_1549">US Airways Flight 1549</a> encountered a flock of migrating Canadian geese shortly after taking off from LaGuardia Airport in New York. Both of the plane’s engines failed, and captain Sully Sullenberger was forced to pilot it to an unpowered landing in the Hudson River.</p> <p>Between 2008 and 2017, the Australian Transport Safety Board recorded <a href="https://www.atsb.gov.au/publications/2018/ar-2018-035">16,626 bird strikes</a>. In America, the Federal Aviation Administration reported <a href="https://www.washingtonpost.com/travel/2023/04/25/bird-strike-plane-american-airlines/">17,200 bird strikes</a> in 2022 alone.</p> <h2>Where do bird strikes happen, and what are the effects?</h2> <p>According to the <a href="https://www.icao.int/Pages/default.aspx">International Civil Aviation Organization</a>, 90% of bird strikes happen near airports. In general, this is while aircraft are taking off or landing, or flying at lower altitudes where most bird activity occurs.</p> <p>The effect of bird strike depends on many factors including the type of aircraft. Outcomes may include shutting down an engine, as may have happened with the Virgin Australia flight. This plane was a Boeing 737-800, which has the capability to fly on a single engine to an alternate airport.</p> <p>In smaller aircraft, particularly single-engine aircraft, bird strikes can be fatal. Since 1988, <a href="https://aawhg.org/#:%7E:text=The%20majority%20happen%20at%20low,billion%20in%20aircraft%20damage%20annually.">262 bird strike fatalities</a> have been reported globally, and 250 aircraft destroyed.</p> <h2>How do manufacturers and pilots defend against bird strike?</h2> <p>Most <a href="https://aawhg.org/">bird strikes</a> occur early in the morning or a sunset when birds are most active. Pilots are trained to be vigilant during these times.</p> <p>Radar can be used to <a href="https://detect-inc.com/aircraft-birdstrike-avoidance-radar/?gad_source=1&amp;gclid=Cj0KCQjwvb-zBhCmARIsAAfUI2ullN-s0MdDfzV2Hu9fLfdr8pKQCuyZWsoJfRN2W5s-tSm6Vo0wHgwaAgBMEALw_wcB">track flocks of birds</a>. However, this technology is ground-based and not available worldwide so it can’t be used everywhere.</p> <p>The two largest manufacturers of passenger jets, Boeing and Airbus, use <a href="https://aerospaceengineeringblog.com/jet-engine-design/">turbofan engines</a>. These use a series of fan blades to compress air before adding fuel and flame to get the thrust needed to take off.</p> <figure><iframe src="https://www.youtube.com/embed/lgspIiTFWIk?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">Engine manufacturers test how well they are likely to stand up to a bird strike.</span></figcaption></figure> <p>Bird strike in one of these engines can cause severe damage to the fan blades, causing the engine to fail. Engine manufacturers test the safety of these engines by firing <a href="https://www.aerospacetestinginternational.com/news/engine-testing/faa-proposes-new-engine-test-for-bird-ingestion.html">a high-speed frozen chicken</a> at them while the engine is operating at full thrust.</p> <p>The Australian Government’s Civil Aviation Safety Authority <a href="https://www.casa.gov.au/wildlife-hazard-management">circular on wildlife hazard management</a> outlines what airports should do to keep birds and animals away from the vicinity of the airport. One technique is to use small gas explosions to mimic the sound of a shotgun to deter birds from loitering near the runway. In areas with high bird populations, airports may also use certain grasses and plants that do not attract the birds.<!-- Below is The Conversation's page counter tag.

Almost half the men surveyed think they could land a passenger plane. Experts disagree

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/guido-carim-junior-1379129">Guido Carim Junior</a>, <a href="https://theconversation.com/institutions/griffith-university-828">Griffith University</a>; <a href="https://theconversation.com/profiles/chris-campbell-1414564">Chris Campbell</a>, <a href="https://theconversation.com/institutions/griffith-university-828">Griffith University</a>; <a href="https://theconversation.com/profiles/elvira-marques-1362476">Elvira Marques</a>, <a href="https://theconversation.com/institutions/griffith-university-828">Griffith University</a>; <a href="https://theconversation.com/profiles/nnenna-ike-1490692">Nnenna Ike</a>, <a href="https://theconversation.com/institutions/griffith-university-828">Griffith University</a>, and <a href="https://theconversation.com/profiles/tim-ryley-1253269">Tim Ryley</a>, <a href="https://theconversation.com/institutions/griffith-university-828">Griffith University</a></em></p> <p>Picture this: you’re nestled comfortably in your seat cruising towards your holiday destination when a flight attendant’s voice breaks through the silence:</p> <blockquote> <p>Ladies and gentlemen, both pilots are incapacitated. Are there any passengers who could land this plane with assistance from air traffic control?</p> </blockquote> <p>If you think you could manage it, you’re not alone. <a href="https://today.yougov.com/topics/politics/survey-results/daily/2023/01/02/fd798/3">Survey results</a> published in January indicate about one-third of adult Americans think they could safely land a passenger aircraft with air traffic control’s guidance. Among male respondents, the confidence level rose to nearly 50%.</p> <p>Can a person with no prior training simply guide everyone to a smooth touchdown?</p> <p>We’ve all heard stories of passengers who saved the day when the pilot became unresponsive. For instance, last year <a href="https://www.youtube.com/watch?v=qbMoyWukjbs">Darren Harrison</a> managed to land a twin-engine aircraft in Florida – after the pilot passed out – with the guidance of an air traffic controller who also happened to be a flight instructor.</p> <p>However, such incidents tend to take place in small, simple aircraft. Flying a much bigger and heavier commercial jet is a completely different game.</p> <h2>You can’t always rely on autopilot</h2> <p>A pilot spends about 90% of their time monitoring autopilot systems and making sure everything is working as intended. The other 10% is spent managing problems, taxiing, taking off and landing.</p> <p>Takeoffs and landings are arguably the most difficult tasks pilots perform, and are always performed manually. Only on very few occasions, and in a handful of aircraft models, can a pilot use autopilot to land the aircraft for them. This is the exception, and not the rule.</p> <p>For takeoff, the aircraft must build up speed until the wings can generate enough lift to pull it into the air. The pilot must <a href="https://youtu.be/16XTAK-4Xbk?si=66yDo5g5I086Q2y2&amp;t=65">pay close attention</a> to multiple instruments and external cues, while keeping the aircraft centred on the runway until it reaches lift-off speed.</p> <p>Once airborne, they must coordinate with air traffic control, follow a particular path, retract the landing gear and maintain a precise speed and direction while trying to climb.</p> <p>Landing is even more complicated, and requires having precise control of the aircraft’s direction and descent rate.</p> <p><a href="https://youtu.be/u_it9OiTnSM?si=xNZrLB9ZH870LEa3&amp;t=360">To land successfully</a>, a pilot must keep an appropriate speed while simultaneously managing gear and flap configuration, adhering to air traffic regulations, communicating with air traffic control and completing a number of paper and digital checklists.</p> <p>Once the aircraft comes close to the runway, they must accurately judge its height, reduce power and adjust the rate of descent – ensuring they land on the correct area of the runway.</p> <p>On the ground, they will use the brakes and reverse thrust to bring the aircraft to a complete stop before the runway ends. This all happens within just a few minutes.</p> <figure><iframe src="https://www.youtube.com/embed/Nyx4NyMrvOs?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>Both takeoff and landing are far too quick, technical and concentration-intensive for an untrained person to pull off. They also require a range of skills that are only gained through extensive training, such as understanding the information presented on different gauges, and being able to coordinate one’s hands and feet in a certain way.</p> <h2>Training a pilot</h2> <p>The journey from student to commercial pilot is a long one. It normally starts with a recreational licence, followed by a private licence, and then a commercial licence (which allows them to fly professionally).</p> <p>Even before stepping into a cockpit, the student must study aerodynamics, air law and flight rules, meteorology, human factors, navigation, aircraft systems, and performance and flight planning. They also need to spend time learning about the specific aircraft they will be flying.</p> <p>Once the fundamentals are grasped, an instructor takes them for training. Most of this training is conducted in small, lightweight aircraft – with a simulator introduced briefly towards the end.</p> <p>During a lesson, each manoeuvre or action is demonstrated by the instructor before the student attempts it. Their attempt may be adjusted, corrected or even terminated early in critical situations.</p> <p>The first ten to fifteen lessons focus on takeoff, landing, basic in-flight control and emergency management. When the students are ready, they’re allowed to “go solo” – wherein they conduct a complete flight on their own. This is a great milestone.</p> <p>After years of experience, they are ready to transition to a commercial aircraft. At this point they might be able to take off and land reasonably well, but they will still undergo extensive training specific to the aircraft they are flying, including hours of advanced theory, dozens of simulator sessions and hundreds of hours of real aircraft training (most of which is done with passengers onboard).</p> <p>So, if you’ve never even learned the basics of flying, your chances of successfully landing a passenger aircraft with air traffic control’s help are close to zero.</p> <h2>Yet, flying is a skill like any other</h2> <p>Aviation training has been democratised by the advent of high-end computers, virtual reality and flight simulation games such as Microsoft’s <a href="https://www.flightsimulator.com/">Flight Simulator</a> and <a href="https://www.x-plane.com/">X-Plane</a>.</p> <p>Anyone can now rig up a desktop flight simulator for a few thousand dollars. Ideally, such a setup should also include the basic physical controls found in a cockpit, such as a control yoke, throttle quadrant and pedals.</p> <p>Flight simulators provide an immersive environment in which professional pilots, students and aviation enthusiasts can develop their skills. So if you really think you could match-up against a professional, consider trying your hand at one.</p> <p>You almost certainly won’t be able to land an actual passenger plane by the end of it – but at least you’ll gain an appreciation for the immense skill pilots possess.<!-- Below is The Conversation's page counter tag.

Why you shouldn’t worry if the plane cabin fills with fog

<p dir="ltr">A savvy traveller has shared why plane cabins can fill with fog, and why you need not to worry about it. </p> <p dir="ltr">Passenger Savannah Gowarty posted a video of the suspiciously looking inflight mist and condensation on a domestic US flight, with the video garnered over 13.1 million views, and amazing and confusing commentators questioning what was going on.</p> <p dir="ltr">In response to the viral video, a Federal Aviation Administration (FAA) spokesperson told <em><a href="https://cnn.com/travel">CNN Travel</a></em> what it means. </p> <p dir="ltr">The short answer: it's a natural occurrence that usually only lasts a short while, and it's nothing to worry about.</p> <p dir="ltr">"On hot and relatively humid days, cold air from the aircraft's air conditioning system mixes with the warmer, humid cabin air and lowers it to the dew point, creating fog," the spokesperson said. </p> <p dir="ltr">"The fog is generally short-lived as the cooled air quickly warms above the dew point."</p> <p dir="ltr">When an airplane is waiting on the ground pre-departure, the aircraft cabin air is kept cool "either from an external ground air conditioning unit or the aircraft's own Auxiliary Power Unit (APU)," as the FAA spokesperson explains.</p> <p dir="ltr">"Both provide cold air (usually much cooler than the ambient temperature) which can temporarily lower the dew point of the aircraft cabin air enough to create fog."</p> <p dir="ltr">Climate scientist Indrani Roy emphasised that neither mist nor any resulting condensation is "cause for alarm."</p> <p dir="ltr">The FAA spokesperson went on to explain that "aircraft cabin fog usually dissipates very quickly."</p> <p dir="ltr">"This is due to the colder air (which lowered the cabin air temperature to its dew point) quickly warms back above the dew point. Once that happens, the fog will disappear.”</p> <p dir="ltr">“Many times, the fog only appears as it comes out of the vent, exists for 1-2 seconds and then is gone."</p> <p dir="ltr"><em>Image credits: Shutterstock </em></p>

How do airplanes fly? An aerospace engineer explains the physics of flight

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/craig-merrett-1509278">Craig Merrett</a>, <a href="https://theconversation.com/institutions/clarkson-university-4276">Clarkson University</a></em></p> <p>Airplane flight is one of the most significant technological achievements of the 20th century. The <a href="https://airandspace.si.edu/explore/stories/wright-brothers">invention of the airplane</a> allows people to travel from one side of the planet to the other in less than a day, compared with weeks of travel by boat and train.</p> <p>Understanding precisely why airplanes fly is an ongoing challenge for <a href="https://www.clarkson.edu/people/craig-merrett">aerospace engineers, like me</a>, who study and design airplanes, rockets, satellites, helicopters and space capsules.</p> <p>Our job is to make sure that flying through the air or in space is safe and reliable, by using tools and ideas from science and mathematics, like computer simulations and experiments.</p> <p>Because of that work, flying in an airplane is <a href="https://usafacts.org/articles/is-flying-safer-than-driving/">the safest way to travel</a> – safer than cars, buses, trains or boats.

Engineers use these forces to help design the shape of the airplane, the size of the wings, and figure out how many passengers the airplane can carry.</p> <p>For example, when an airplane takes off, the thrust must be greater than the drag, and the lift must be greater than the weight. If you watch an airplane take off, you’ll see the wings change shape using flaps from the back of the wings. The flaps help make more lift, but they also make more drag, so a powerful engine is necessary to create more thrust.</p> <p>When the airplane is high enough and is cruising to your destination, lift needs to balance the weight, and the thrust needs to balance the drag. So the pilot pulls the flaps in and can set the engine to produce less power.</p> <p>That said, let’s define what force means. According to <a href="https://ca.pbslearningmedia.org/resource/4079abf0-7a4b-4f49-80ad-c69cd06a80f9/newtons-second-law-of-motion/">Newton’s Second Law</a>, a force is a mass multiplied by an acceleration, or F = ma.</p> <p>A force that everyone encounters every day is <a href="https://spaceplace.nasa.gov/what-is-gravity/en/#:%7E">the force of gravity</a>, which keeps us on the ground. When you get weighed at the doctor’s office, they’re actually measuring the amount of force that your body applies to the scale. When your weight is given in pounds, that is a measure of force.</p> <p>While an airplane is flying, gravity is pulling the airplane down. That force is the weight of the airplane.</p> <p>But its engines push the airplane forward because they create <a href="https://www1.grc.nasa.gov/beginners-guide-to-aeronautics/what-is-thrust/">a force called thrust</a>. The engines pull in air, which has mass, and quickly push that air out of the back of the engine – so there’s a mass multiplied by an acceleration.</p> <p>According to <a href="https://www.youtube.com/watch?v=a-wh3fJRdjo">Newton’s Third Law</a>, for every action there’s an equal and opposite reaction. When the air rushes out the back of the engines, there is a reaction force that pushes the airplane forward – that’s called thrust.</p> <p>As the airplane flies through the air, the shape of the airplane pushes air out of the way. Again, by Newton’s Third Law, this air pushes back, <a href="https://www1.grc.nasa.gov/beginners-guide-to-aeronautics/what-is-drag/#:%7E">which leads to drag</a>.</p> <p>You can experience something similar to drag when swimming. Paddle through a pool, and your arms and feet provide thrust. Stop paddling, and you will keep moving forward because you have mass, but you will slow down. The reason that you slow down is that the water is pushing back on you – that’s drag.</p> <h2>Understanding lift</h2> <p><a href="https://www1.grc.nasa.gov/beginners-guide-to-aeronautics/what-is-lift/">Lift</a> is more complicated than the other forces of weight, thrust and drag. It’s created by the wings of an airplane, and the shape of the wing is critical; that shape is <a href="https://howthingsfly.si.edu/media/airfoil#:%7E">known as an airfoil</a>. Basically it means the top and bottom of the wing are curved, although the shapes of the curves can be different from each other.</p> <p>As air flows around the airfoil, <a href="https://www.youtube.com/watch?v=UO75jDwGCdQ">it creates pressure</a> – a force spread out over a large area. Lower pressure is created on the top of the airfoil compared to the pressure on the bottom. Or to look at it another way, air travels faster over the top of the airfoil than beneath.</p> <p>Understanding why the pressure and speeds are different on the top and the bottom is <a href="https://airandspace.si.edu/multimedia-gallery/lift-and-copjpg">critical to understand lift</a>.

Here’s what happens to your body during plane turbulence – and how to reduce the discomfort it causes

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/adam-taylor-283950">Adam Taylor</a>, <a href="https://theconversation.com/institutions/lancaster-university-1176">Lancaster University</a></em></p> <p>This week has seen another barrage of <a href="https://www.theguardian.com/uk-news/2024/jan/22/uk-weather-storm-jocelyn-to-follow-isha-with-more-strong-winds-and-heavy-rain">unsettled weather</a> sweep across the UK, with many flights delayed or cancelled. Some of those who were fortunate enough to take off found themselves arriving at destinations that weren’t on their boarding passes – such as passengers travelling from Stansted to Newquay who eventually diverted to <a href="https://uk.news.yahoo.com/storm-isha-creates-flight-diversion-142821278.html">Malaga</a>.</p> <p>One thing that was consistently described by passengers was that parts of the flights and the attempted landings were some of the most unnerving they’d ever experienced, due to turbulence.</p> <p>Turbulence results from uneven air movement, which is <a href="https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2023GL103814">increasing</a> in frequency. If you turn your hair dryer on at home and hold it still, the air moves at a constant rate, but once you begin drying your hair and moving the hairdryer around, the air movement becomes uneven, that is to say, turbulent.</p> <p>Although turbulence may be unnerving and make you feel unwell, it is important to recognise that it is very common and typically <a href="https://pubmed.ncbi.nlm.nih.gov/18018437/">nothing to worry about</a> if you’re in your seat with your seatbelt fastened.</p> <h2>How the body detects and responds to turbulence</h2> <p>The body recognises itself within any environment. Its relationship with objects in terms of distance and direction is called <a href="https://www.sciencedirect.com/science/article/abs/pii/B9780123750006003414">spatial orientation</a>.</p> <p>When flying, this is typically moving forwards, ascending, some turns and a descent. However, turbulence disrupts this relationship and confuses the sensory information being received by the brain – it makes the body want to respond or recalibrate.</p> <p>Our inner ears play a pivotal role in all this. It consists of complex apparatuses that undertake more than hearing. These include the cochlea, <a href="https://www.ncbi.nlm.nih.gov/books/NBK279394/">three semi-circular canals</a>, <a href="https://radiopaedia.org/articles/utricle-ear?lang=gb">the utricle</a> and <a href="https://radiopaedia.org/articles/saccule-ear-1?lang=gb">the saccule</a>.</p> <p>The cochlea is responsible for hearing. It converts <a href="https://www.ncbi.nlm.nih.gov/books/NBK531483/">sound energy into electrical energy</a> that is then “heard” by the brain. The remaining structures are responsible for the balance and position of the head and body. The semi-circular canals are positioned in a vertical (side to side), horizontal and front-to-back plane, detecting movement in a nodding, shaking and touching ear-to-shoulder direction.</p> <p>Attached to these canals are <a href="https://www.ncbi.nlm.nih.gov/books/NBK532978/">the utricle and saccule</a>, which can detect <a href="https://www.ncbi.nlm.nih.gov/books/NBK10792/">movement</a> and <a href="https://www.cell.com/current-biology/pdf/S0960-9822(05)00837-7.pdf">acceleration</a>.</p> <p>All of these apparatuses use microscopic hair cells in a specialised fluid called <a href="https://www.ncbi.nlm.nih.gov/books/NBK531505/">endolymph</a> that flows with the head to create a sense of movement. When the plane encounters turbulence, this fluid moves around, but unpredictably. It takes <a href="https://www.ncbi.nlm.nih.gov/books/NBK518976/">about ten to 20 seconds</a> for the fluid to recalibrate its position, while the brain struggles to understand what is going on.</p> <p>When the aircraft hits turbulence, the balance apparatus <a href="https://www.frontiersin.org/articles/10.3389/fneur.2023.949227/full">cannot distinguish</a> the movement of the plane from that of the head, so the brain interprets the aircraft movement as that of the head or body. But this doesn’t match the visual information being received, which causes sensory confusion.</p> <p>The reason the inner ear causes so much confusion is because during flights you are devoid of your primary sensory tool relative to the external environment – your sight and the horizon.</p> <p>Eighty per cent of <a href="https://www.ncbi.nlm.nih.gov/books/NBK518976/">spatial information</a> comes from your eyes during flight. However, you only have the seat in front of you or the cabin as a reference point, which means your inner ear becomes the dominant sensory message to the brain during turbulence and disrupts the <a href="https://www.ncbi.nlm.nih.gov/books/NBK545297/">“vestibulo-ocular reflex”</a>. This reflex keeps your vision <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4130651/">aligned</a> with your balance or expected position.</p> <p>Vision is the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6777262/">most valued</a> of the senses and one-third of the brain is attributed to its function, reinforcing its importance in spatial orientation.</p> <p>This sensory mixed messaging often results in things like dizziness and sweating as well as gastrointestinal symptoms, such as <a href="https://www.airmedicaljournal.com/article/S1067-991X(02)70038-2/fulltext">nausea and vomiting</a>.</p> <p>Motion sickness can be triggered by turbulence and although research into specific airsickness is limited, other modes that induce motion sickness suggest that <a href="https://pubmed.ncbi.nlm.nih.gov/16018346/">women</a> are <a href="https://pubmed.ncbi.nlm.nih.gov/26466829/">more susceptible</a> than men, particularly in the <a href="https://pubmed.ncbi.nlm.nih.gov/16235881/">early stages</a> of the menstrual cycle.</p> <p>The turbulence also causes an increase in your heart rate, which is already higher than normal when flying because of a <a href="https://pubmed.ncbi.nlm.nih.gov/15819766/">decrease in oxygen saturation</a>.</p> <h2>What about the pilots?</h2> <p>Commercial pilots accrue thousands of hours at the controls, they are subject to the same forces as the passengers.</p> <p>Over time, they can <a href="https://academic.oup.com/milmed/article/180/11/1135/4160573">adapt to these forces</a> and <a href="https://pubmed.ncbi.nlm.nih.gov/15828634/">experiences</a>, but they also have a couple of additional resources that most passengers don’t.</p> <p>They have the view out of the cockpit windows, so have a horizon to use as a reference point and can see what lies immediately ahead.</p> <p>If it is cloudy or visibility is low, their instruments provide additional visual <a href="https://www.faa.gov/sites/faa.gov/files/regulations_policies/handbooks_manuals/aviation/phak/19_phak_ch17.pdf">reference</a> to the position of the aircraft. This doesn’t mean they are immune to the effects of turbulence, with some studies reporting up to <a href="https://pubmed.ncbi.nlm.nih.gov/26540704/">71% of trainee pilots</a> reporting episodes of airsickness.</p> <h2>How to reduce the discomfort</h2> <p>A window seat can help, or even looking out the window. This gives the brain some sensory information through visual pathways, helping calm the brain in response to the vestibular information it is receiving.</p> <p>If you can get one, a seat towards the front or over the wing reduces the effects of turbulence.</p> <p>Deep or rhythmical breathing can help reduce motion sickness induced by turbulence. Focusing on your breathing <a href="https://pubmed.ncbi.nlm.nih.gov/25945662/">calms the nervous system</a>.</p> <p>Don’t reach for the alcohol. While you may feel it calms your nerves, if you hit turbulence it’s going to interfere with your <a href="https://pubmed.ncbi.nlm.nih.gov/7610847/">visual and auditory processing</a> and increase the likelihood of vomiting.</p> <p>If you suffer from motion sickness and are worried about turbulence while flying, then there are also <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6241144/">drugs that can help</a>, including certain <a href="https://www.nhs.uk/medicines/cinnarizine/about-cinnarizine/">antihistamines</a>.</p> <p>Finally, it’s important to remember that although turbulence can be unpleasant, aircraft are designed to withstand the forces it generates and many passengers, even frequent fliers, will rarely encounter the most severe categories of turbulence because pilots actively plan routes to avoid it.<!-- Below is The Conversation's page counter tag.

"Not one ounce of compassion”: BBC star kicked off plane over daughter's allergy

<p>A BBC weather presenter and her family have been kicked off a plane after asking passengers to be wary of her daughter's peanut allergy. </p> <p>British weather presenter Georgie Palmer was flying from London to Turkey with her husband Matt and their daughters Annie and Rosie, as the family boarded their flight at Gatwick Airport with SunExpress airlines. </p> <p>Georgie and her family were kicked off the plane shortly after boarding, after the 49-year-old mother ran into issues around her daughter's severe allergy to peanuts.</p> <p>According to Palmer, she has requested that the captain make an announcement to all passengers asking them not to eat any peanut products on the flight, but the pilot refused. </p> <p>Palmer then took matters into her own hands and one by one asked passengers not to consume peanuts on the four-hour flight, before being asked to disembark the aircraft.</p> <p>The weather presenter took to Instagram to share her side of the story with a lengthy post. </p> <p>She began, “I thanked the beautiful souls on our plane for helping us. Many of them hugged, cheered and held our hands as we were forced to disembark."</p> <p>“The SunExpress captain and cabin crew refused to make the standard announcement on behalf of our daughter. We gently asked the passengers at the front of the plane to share our request."</p> <p>“Row by row, all the passengers turned back to kindly ask the row behind to please not eat nuts on the flight. It was calm, earnest and with an overwhelming sense of solidarity and empathy.”</p> <p>Georgie added: “There’s no beef with simple asks like these. People get it!"</p> <p>“We were hoofed off the plane after the angry little captain shouted at us from the cockpit.”</p> <p>She concluded by saying they were discriminated against for “simply having an allergy”.</p> <p>Georgie told the <a title="www.dailymail.co.uk" href="https://www.dailymail.co.uk/news/article-13457399/bbc-weather-presenter-Georgie-Palmer-flight-nuts.html" target="_blank" rel="noopener"><em>Daily Mail</em>,</a> “The captain decided because of my daughter’s allergy he didn’t want to fly with her on board."</p> <p>“When he found out I had spoken to the other passengers he was screaming at me from the cockpit. He was so angry, the next thing I knew we were told to get off the plane."</p> <p>“How we were treated was disgusting – nobody working on that plane showed one ounce of compassion.”</p> <p>A SunExpress spokesman then shared the airline's version of events, claiming that Georgie's husband had become aggressive, and kicked the family off the plane with their best interests at heart. </p> <p>The statement said, “We take the safety of our passengers very seriously. Shortly after boarding our flight, the passenger raised a concern about one of his family group having a serious peanut allergy."</p> <p>“They requested an announcement to other passengers. We refrain from making these kinds of announcements. Like many other airlines, we cannot guarantee an allergen-free environment on our flights, nor can we prevent other passengers from bringing food items containing allergens on board."</p> <p>“Due to the insistent behaviour of the passenger to others on board, the captain decided it would be safest if the family did not travel."</p> <p>“When this was explained to the passenger, he behaved aggressively towards our crew members and tried to gain access to the cockpit. To ensure the safety of our crew and our passengers on board, we cannot tolerate aggressive and unruly behaviour on our flights."</p> <p>“Our website states that passengers must notify us 48 hours in advance of any special care required due to a medical condition. No such notification was received from the passengers in this instance.”</p> <p>According to <em><a href="https://www.thesun.co.uk/tv/28140666/bbc-family-flight-passengers-peanuts-allergy/" target="_blank" rel="noopener">The Sun</a></em>, Mr Sollom denies acting aggressively.</p> <p>The differing versions of events have divided many on social media as thousands weighed in on the debacle, with plenty of users siding with the pilot.</p> <p>“The pilot is a national treasure,” one person wrote.</p> <p>“As they should have been,” a second wrote, referring to the family getting kicked off.</p> <p>“Would have booted them off as well,” another agreed. </p> <p>A fourth wrote: “I think this story would be found under Self Entitlement in the dictionary.”</p> <p><em>Image credits: Instagram </em></p>
