Did you link the correct flight? Because your link says something entirely different.

Yep, it says entirely different because Russians are exceptionally good liars. But if you read court documents, then you will see that no hexogen is found at plane crash site, which is impossible for missile warhead made with 60% of hexogen. Moreover, military training was recorded on video, and this record was shown right after incident. 3 missiles was launched, 2 of them hit their targets, one missed. Third rocket blown up in the air by command from ground. Moment of blow up is visible on video.

I had small battle in Wikipedia and won. Now page says correct information.
