I hope this kind of conspiracy theory raving will not make it onto the HN frontpage too often.
As to the crash, it was a CFIT (controlled flight into terrain). There are cockpit recordings right until the moment the plane hit the tree and then the ground. No explosions.
Yep, it's very off topic. Conspiracy theory debates are about the last thing you want on a site like this.
EDIT: I should clarify that "accident" is a specific class of event in aircraft accident investigation, together with "incident". It's literally "aviation terminology" stuff.
A proof of an explosion (which this is not) would be proof of an assasination.
Pity the facts, right?
"But the tree impact that supposedly precipitated the crash wouldn't have caused enough wing damage to down the plane, said Binienda ... It's absolutely impossible that the wing sheared and then it crashed the way [government investigators] described" - that's all they have, an opinion of a conspiracy nut. I don't buy this for a second, and here's why:

EDIT:
Oh, and the explosion would be heard by both people on the ground (some random guy was right next to the crash scene, he even put a video on youtube), and on the black box recording (transcript available).
The wreck was left on open air for several months: http://en.rian.ru/world/20110112/162110789.html

I'm saying there's no good evidence of it. So far there are natural explanations of what happened, plus the douchebaggery of the Russian politicians.
accident:
[1] An unfortunate incident that happens unexpectedly and unintentionally, typically resulting in damage or injury.
[2] A crash involving road or other vehicles, typically one that causes serious damage or injury.
Alternative research done by the independent experts from US and Australia (like http://goo.gl/YREux by www.simulate-events.com) is being ignored and / or silenced.
