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.
well, from that what i understood due to avilable data the aircraft started to climb at last second and even after seperation of the wing it reached an altitude of roughly 20 meters again and than fell with a bank of more than 90 deg to the ground an at impact fully inverted. hitting the ground "ballistically" with roughly 300 kmh from 20 meters may result in such a destructive damage i would say. but noboy knows for sure.
i speak it out : do you think that the russians shot it down at final? and some people even survived but were "eliminated"?
