After V1, the accelerate-stop distance, the pilot is committed to continue flying. The cargo area of most airliners is not pressurized, so the gash is not an immediate problem. In a case like this, the pilots would want to climb to several thousand feet and evaluate the situation before landing. Looks like the pilot did a great job once it was realized the airplane was damaged of remaining calm and flying the airplan…

Cargo is definitely pressurized. Not heated/aced, but pressurezed the same as the rest of the cabin. Everying from the skin inwards is under 5000ish feet of pressure.

It's heated above freezing too as far as I know, I've never had anything in my luggage freeze.

No. If there was a leak then it wouldnt pressurize properly on the way up. If it was holding pressure, it would probably keep doing so.

It totally depends. A weakened structure can hold pressurization for a while, and then suddenly (and possibly catastrophically) fail. A famous example of this is American Airlines flight 96 (1972): https://en.wikipedia.org/wiki/American_Airlines_Flight_96

Also Japan Airlines Flight 123

Air India, an old antiquated government subsidized airline that should die.

The government has actually been trying to kill it for years but no one wants it: https://money.cnn.com/2018/05/31/investing/air-india-privati...

Can we take a moment and reflect on the fact that all of this data is freely available to anyone? I can sit in front of my computer, or anywhere with my phone, and follow planes around the world with an accuracy of a few meters, and replay the data at a later date.

The various flight trackers all use thousands of receivers around the world, and most of them probably use the same kind of SDR chip that was originally designed for USB TV and radio receivers.

I thought they track things like small vibrations in plane body due to such incidents. How would they detect Bird strike(https://en.m.wikipedia.org/wiki/Bird_strike) if hitting wall go unnoticed? Don't airports have sensors and cameras for such situations to alert Air traffic control immediately?

How will the alcohol ‘leave his system’ in the 4 hours it takes to fly to Dubai from India?

Pilots would have to blow 0.0 but that doesn't mean zero evidence of alcohol. In 4 hours you can metabolise around 4 standard drinks out of your bloodstream. It's not like drugs where any trace is bad because it's illegal. That said, I'm not sure I am on board with the explanation. It could just be that with everything going on in a cockpit it wasn't noticed.

Does reduced air pressure speed up the removal of alcohol via breathing?

If a fever can, wouldn’t alcohol do the same?

Not a pilot, and not trying to be an armchair pilot, but why would he have ascended all the way to 36000 feet? Isn't there a real risk of depressurization with hull damage?

No. If there was a leak then it wouldnt pressurize properly on the way up. If it was holding pressure, it would probably keep doing so.

One minor UX gotcha: the alarm for a pressurization problem on a 737 is not all that intuitive.

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.
