There is a fascinating paper about making conclusions about MH370‘s location by investigating the drift of wreckage by analysing balanidae on those parts: https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2023AV00...

#12Earlier quoted context omitted.
It's possible for the pilot to depressurise the plane and use their dedicated oxygen system to breathe while everyone else on board will pass out after using their individual masks. Doing so will give them 60-90 minutes of extra air, the passengers' masks don't last that long.
The crew had 13 hours of oxygen supply for two pilots.
The supplemental oxygen system was recharged just before this flight as well, so it was at maximum capacity.

#13What happened to that other research team who used amateur radio network packet metadata that had been saved, to track airplanes including MH370 and showed tracks that also matched the satellite pings? Can't remember the name of that group though...

#14If the descent was controlled gliding, the passengers (at least some of them) should be alive upon landing, shouldn’t they? Where are they now? Which theory could explain the absolute silence?
No, the pilot can depressurize the aircraft at high altitude. In such a case, the emergency oxygen masks for passengers will drop, but those are only rated for 15 to 30 minutes. After that Oxygen runs out, assuming the pilot maintains cruise altitude above 25000ft, everyone onboard will lose conscious via hypoxia within 1 minute, and be brain dead within 15 minutes. No one (except the pilot) would be alive to see the…
It's more insidious. At high altitude the drop masks don't provide enough pressure to maintain consciousness for their full rated duration. It's expected that pilots will descend very quickly after a depressurization event to at least 14000 or below. If he stayed at high altitude the passengers probably went unconscious quickly.

Yes, for those interested in this scenario, check Helios Airways Flight 522. I think that's what happened with MH370, except that the depressurization was deliberate. Most likely a single pilot stayed alive and functioning in the cockpit, eventually repressurizing the aircraft.
Perhaps the pilot's goal was to hide all the evidence as well as possible, to create a perfect mystery. Then a controlled ditching would make sense, although it kind of failed considering the debris which eventually reached Africa.

#16In the popular press (1 day ago) "Perfect Hiding Place": Australian Scientist Claims He's Found Where Missing MH370 Plane Is The Malaysian Airlines flight, with 239 people on board, disappeared after leaving Kuala Lumpur Airport in southern Malaysia en route to Beijing, China, on March 8, 2014. Years after its disappearance, an Australian scientist has claimed that he has found the "perfect hiding place" for the miss…

When has that ever been the narrative? It deviated from course, somebody performed that manouver and is "to blame"...

Do you mean underwater? Apologies it's not clear if it's a joke?

Wasn't the conlusion they were finding data that match their conclusion, i.e. they said "it could be here in the ocean" and then they found signals to confirm their guess, but it could be any point in the ocean and they'd be able to find such signals.
In any case I googled the keywords, it's called WSPR, and also found a critique:

And the full critique has suffered from linkrot, but Wayback Machine has it: https://web.archive.org/web/20220221112332/https://dk8ok.org...

“Malaysia Airlines operations…were tracking the plane on the Flight Explorer website, which, as they would only realize hours later, simply continued to display an aircraft’s projected path if its transponder stopped broadcasting position information.”
What in the actual fuck.
“…the supposed signals from the black boxes must have been false. Only much later was it discovered that the signals had probably come from the scanning equipment pinging itself.”
Wat.
“ATSB chose to assume that the plane spiraled in close to the seventh arc because it had not received enough funding to extend the width of the search area to 100 nautical miles.”
WAT.
