So WTH really happened to this Malaysian aircraft??

[yk9001]

Yeah, just taking the plane up to 40,000 plus feet, depressurizing the cabin.  The masks come down for like 15 minutes of oxygen, and then.... bye bye,

I dont get how you can depressurize the cabin? Or why you would have the ability to do so in the first place? I assumed the cabin simply preassurizes on takeoff, due to the seals

If a pressure regulator fails you have to be able to dump pressure or it builds until something blows. Good rule of thumb is anything that builds pressure needs to be able to vent pressure

So in terms of an airliner, its not like opening a window... right? I imagine its more like a vent system?

Yeah it’s a pressure dump valve. Once you dump you should descend to a breathable altitude

Here's a pretty simple explanation of the pressurization system

in the late 70s a college buddy of mine flew with a school singing group to poland. this was around the time when airlines were starting to go no-smoking. he told me that the polish airline they flew on was still a smoking flight, but with an odd set up - the left side of the plane was smoking, the right side was no-smoking.

Problem solved then.

So why cant we smoke on planes now, then?

This is still one of the biggest mysteries I’ve ever come across.  It’s stunning.

Yeah saw that story of the fisherman pulling in a wing.  One of the most interesting air disasters in a good while.
