There's a lot found that very likely belongs to the airplane. It's just not a particularly sexy story. Most likely it's pilot murder-suicide, they did find a highly suspicious looking path in the pilot/copilot's flight sim. Iirc, during the handover from Malaysia to Vietnam ATCs, the pilot depressurizes the cabin, turns off transponders, turns around to avoid civilian radar, and once out of radar reach heads south across the ocean until the fuel runs out. Perhaps to have time to himself or maybe deliberately to not be found, out of shame.
It explains why the two main mysteries – why the initial search was a failure, and the lack of radio and transponder data.
It's also easy to see why authorities and airline operators want to silence it, especially if they have plausible deniability to do so. There is simply less prestige lost in a failed international search-and-rescue than a national airline pilot killing innocent people for god knows what reason.
I don't think airplane hulls are designed for more than 1 Atm of pressure differential between cabin and the outside; according to the wikipedia article [0] on cabin pressurization normal values are between 540 and 690 hPa pressure differential are normal.
If the cabin has an overpressure event, the hull might pop like a balloon, leading to a decompression event.
These seem to talk mostly about diving, where you breathe from a regulated air supply. I assume that air supply is not at 30-100x atmospheric pressure?
Wow, thanks for that, that is a fantastic write-up, and a pretty compelling argument (at least to me) that the mystery of MH370 has been mostly "solved" (spoiler alert: all evidence points to a murder-suicide by pilot Zaharie Ahmad Shah).
