"I'm not sure you understand the implications of this phrase."

I understand very well the implications of what I wrote; the data could well suggest an explosion in front of the aircraft that brought it down. The last data stream was inconvenient data so it was ignored and presented as data from an earlier flight when it was not possible for it to be any normal data stream from any flight.

It would be very easy to run a test and see what a small overpressurization would do to the airspeed, altimeter reading, and AOA sensor readings and proceed, or not, from there according to the findings.

I have worked with the NTSB as an industry representative on general aviation accidents for a number of years and often reviewed their reports at their request before final submission so I know they are capable of errors and mistakes like anyone else. I don't think they are intentionally covering up anything; I think they were pretty much browbeat into not really investigating the accident, deferring to the FBI. Several of the NTSB investigators felt they had to retire before requesting a reopening of the case to avoid reprisals. That does not reflect well on the current organizational culture of the Board.
