The real mystery is what happened between last contact at IGARI and when satellite handshakes resumed. This is the period in most dispute. Evidence at the end of MH370’s flight supports hypoxia so the real question is what caused hypoxia?
We know from the final satellite handshake at 00;11 UTC and two Log on signals at 00:19 UTC that MH370 suffered a flame out and fell into a spiral dive characteristic of known hypoxic flights, so the real mystery is why?
In the final radio communications from MH370 the pilot Zaharie Amadshah (who preferred just to use Shah) gave confused & non procedural responses. His voice at the time was slurred according to his sisters.
12:50:06 ATC Lumpur Control ~ Malaysian Three Seven Zero climb flight level three five zero
12:50:09 MAS370 ~ [acknowledged] Flight level three five zero Malaysian Three Seven Zero
01:01:14 MAS370 ~ Malaysian Three Seven Zero... [No additional comment]
01:01:17 MAS370 ~ Malaysian Three Seven Zero, ah... maintaining three five zero
01:07:55 MAS370 ~ ah Seven... Three Seven Zero, ... maintaining level three five zero
At this point Lumpur Control evidently became confused why MH370 was repeating the same call made just six minutes earlier so they queried MH370:
01:08:00 ATC Lumpur Control ~ Malaysian Three Seven Zero? [NO RESPONSE by MH370]
01:19:24 ATC Lumpur Control ~ Malaysian Three Seven Zero contact Ho Chi Minh 120 decimal 9 Good Night...
01:19:29 MAS370 ~ Good Night Malaysian Three Seven Zero [MH370 failed to give standard protocol read back of ATC instructions]
This exchange of communications indicates MH370’s crew were already suffering hypoxia before they reached IGARI. The turn back had to be a deliberate action, but hypoxia does not infer immediate unconsciousness. It seems MH370 suffered a gradual pressure leak.
Most likely overheated electrical gear in the MEC compartment likely caused smoke triggering a valve to open which discreetly depressurised MH370.
