Would it knock them out if they didn't have a source of oxygen?

etc.

(4,426 posts)Since the plane flew for an extended period after it stopped, and the Satcom link was periodically pinging during that time, it means that the aircraft had normal electrical power available to it and the transponder was just turned off. The Satcom link is not wired into the standby electrical system, so if there was a major power failure that killed the transponder, the Satcom link would have gone out as well. It didn't.
Meaning someone almost certainly deliberately turned off the transponder. Who did that, and why? Nobody knows.

I guess it's easier than imagining some nut wanting to take out that many innocents. Wonder if we'll ever know.

(4,426 posts)Many passenger aircraft fly at that altitude and higher, including some models of the 747 and almost all long range corporate jets. The Concorde typically flew at up to 61,000 feet.
If the cabin was depressurized at that altitude, anyone without supplemental oxygen would die in a fairly short period of time. That's why there are emergency masks that drop automatically at each passenger seat if there is a depressurization event. Those masks are typically good for around 20 minutes, during which time the pilots are supposed to rapidly descend to 10,000 feet so that people can breathe once the oxygen runs out.
If the airplane depressurizes at high altitude and the pilots do not descend (their oxygen mask system is separate and lasts longer), once the passenger emergency oxygen is used up, it's lights out. No sane pilot would allow that to happen. It would effectively be mass murder.

Thanks.

(81,861 posts)But it has been picked up by many of the big sources. MSNBC broke into prison documentaries to report it. Also seen it on ABC, Sky, Hindustan Times, and several others.

Thanks for the link. It has not started yet. These things never begin on schedule.

(81,861 posts)The disclaimer was that accuracy couldn't be guaranteed after the transponder was turned off.

(40,416 posts)Basically anybody, I guess.
In other words, it's bullshit.

(16,926 posts)As one expert explained last night, military radar doesn't rely on enemy planes advertising their position with transponders; there is additional geometry built in to supply altitude info.
