That is a good question. I think the people who were near the fuselage were probably burned up. But the one that were closer to the front of the plane or at the very back of the plane did not burn at all.
So far....
1. Unverified reports of advance missile fire on a commercial airplane
2. Many sides blaming Russia without proof
3. FAA's report warned people not to fly over Ukraine 3months ago

4. The bodies look attached and recognizable, so there is no way they were shot down 33,000 feet and parts are not chard-broiled or extremely all over the place, hundreds of yards from the site.
5. All of the shot down capability the eastern Ukraine fighters have been using gla man-portable air defense missiles which are known that they can't reach 33,000 feet.
Because they weren't using MANPADS dumbass.
