Aerobat77, you could be right (partly at least). However, there are some other things that require further investigation.
Recovered data from RA, TAWS, FMS, etc. indicate that there was a deep roll but not the barrel roll as 2 official reports stated. Another thing that has puzzled scientists specializing in mechanical engineering was a crash site. There were literally thousands of plane debris scattered at the crash scene. With no barrel roll, low altitude (few meters off the ground), low speed, no deep impact traces the plane could not desintegrated the way it was officialy stated.
