I am not a conspirologist, but the official findings don't match up.
The plane crashed with separated part of left wing. That's the fact.
As I showed above, there is no direct proof for barell roll as claimed.
Have you ever seen videos showing the planes hitting the ground with 65-90 deg roll? In Smolensk, there were shallow impact traces on the ground, no fire-balls and thousands of debris.
What is your personal view on that matter?
