I would be interested in someone with Russian language skills translating what is being said between 2:07 and 2:14 in this video. Looking at the pockmarks/scrapes - I assume 95% chance these occurred on ground strike before rolling 180 but just to be sure... There are also rear seats later in the video which have been mentioned previously, one of which seems to show some entry or exit holes - again, may be related to events during disintegration, but maybe not.
