In contrast, I can't say I've ever heard of seats in cars having this problem. Is it because plane seats are highly optimised for weight?

My wife knows of two fatal car accidents caused by this. Don't adjust your seat whilst driving peeps, and make sure it clicked into position before you drive if you adjust it.

Wow, thanks for the info. If you happen to have links for them, I'd be curious to read more.

Unfortunately don’t have time for a long post at the moment, but as an airline pilot and instructor/check pilot, I can say that extreme incompetence exists in the airline world, especially in Africa, India, SE Asia. There could be some very good reasons that they chose to continue, and often I learn those reasons when the facts are released, discovering that a good decision was made. I’ll be following the investigati…

Hong Kong is East Asia.

A good reason would be fuel weight on possibly damaged landing gear. Also, the airport wasn't good anymore. They had just destroyed the Instrument Landing System at the end of the runway. Nobody should land there.

The ILS is not necessary for landing in VFR conditions, although non-USA pilots tend to rely on it as a crutch.

This is being downvoted, though is true to my understanding -- not uncommon for even the largest airports to have both ILS and non-ILS runways. (e.g. Runway 1L at SFO is non-ILS.)

In this particular case, the departure airport only had one runway, and immediately after the botched takeoff it was at least in dire need of a debris check, so I wouldn't be surprised if the airport was closed while that happened. Wouldn't have taken four hours, though, and I suspect that they would do whatever they could to accomodate an emergency aircraft had the pilot declared.

If your car seat slides back unexpectedly, the most likely problem will be a decreased ability to press down in the accelerator. The seat would generally slide back only under forwards acceleration. Under braking the seat would slide forward giving positive pressure onto the brake pedal.

It also diminishes your ability to brake. And if you do slide back, and the seat then locks in place , that could be serious.

You would keep steering the car, while also attempting to unlock the seatbelt. Depending on the car, you could also activate the parking brake. (In my car, it's a button on the center console, and it can be activated at high speed and will provide emergency braking.)

"Serious" is still not the same as "fatal", even if your car hits something. If your plane stalls and falls hundreds of feet, my understanding is that the fatality rate is going to approximate 100%.

Honest question: why aren't pilots forced to take alcohol tests before flights? There was some JetBlue incident about 10 years ago, IIRC.

Are forced alcohol tests given anywhere?

In some places bus drivers have mandatory breathalyzer testing at the start of their shift.

Not really - If there had a been a gash in pressurization, they would have caught it on the way up. The 737 is a _tank_. It has more or less the same wing load as a F-16. It takes a lot to shake around - it's every bit the 1950s build 707 chassis, and like the old 50s lathe - it can take a hit and keep going.

Plenty of 737's have had explosive depressurization with injuries or fatalities, most recently this year https://www.bbc.com/news/world-us-canada-43818752 and one of the most famous incidents (in the U.S.) https://en.wikipedia.org/wiki/Aloha_Airlines_Flight_243 Both were from fatigue, but fatigue doesn't have to be a gradual thing; it could come from a single hit that causes the pressure vessel to fail at altitude. S…

The difference is that happens at altitude. When the plane has just taken off there is no pressure differential. There’s no energy TO explode.

I'd rather not trust my life to "probably". If there was some damage to the hull or a cargo door that could lead to failure, it's under more stress and is more of a hazard as the altitude increases.

Less stress imho. At altitude the forces on wings/structure are far less than during takeoff.

Incorrect. In level flight the wings have - by definition - 1g of upward load. Regardless of speed or altitude.

I have been trying to go over how this could happen. The damage to the wall seems so severe that I would image even over the sound of the engine the pilot would hear and notice that they had hit a wall. Flying the plane at this point would be risking their life. The first thing that came to my mind was the only reason a pilot would risk his life is if his life was already at risk and if he had been drinking when he h…

Over at http://pprune.org the suggestion is that the pilot's seat was not locked into position correctly and slid back during takeoff. This caused the pilot to pull back on the stick too early and his instinct was the push forward to keep the plane on the correct trajectory. He likely over-corrected and ended up flying 6ft off the ground at the end of the runway where the landing gear caught an antenna and the chainl…

Looks like they went halfway across the Arabian Sea before turning around, strange... https://www.flightradar24.com/data/flights/ix611#1e2da319

What caused them to retun in half way? Report says Trichy airport informed pilot about posssible damage to plane. Pilot ignored it saying everything is green. What happened in 4hrs to divert back to Mumbai is still mystery. Will be interesting to see full report

Is it possible that Dubai refused to let them land with a flyable but potentially pretty broken plane?
