==BUK is not rocket shell () shell be heard for many miles () BUK is a big rocket. but no one heard it, did not see. Why is it not mentioned in the article?== 
 This may be true,http://lenta.ru/articles/2014/07/18/buk/ but doubtshttp://www.youtube.com/watch?v=Nx7KQmSzQfU that there is no published evidence (flame rocket motor during the flight, the rocket launch sound, sound rocket flight, the trail in the sky from the missiles warhead explosion noiseand the effects at aircraft wreckage left behind by from the the warhead (many hundreds of fragments = punctures)). Any of effects for the rocket start, noticeable at 10 or even 100 times smaller missiles (MANPADS for example start from the ground can really be seen Pilot-target). The explosion of the warhead missiles Buk is very noticeable. Quote (translated) - Why no pictures or insurgent rocket contrail after an impressive start? Why no journalists BBC, nor staff TheTelegraph, who conducted extensive research in the snow and in areas south of it, could not find any local eyewitness alleged missile launch?.http://oko-planet.su/politik/politikukr/252982-podrobnyy-ekspertnyy-analiz-krusheniya-boinga.htmlhttp://via-midgard.info/news/in_midgard/reportazh-rassledovanie-bbc-vnezapno-propal-s.htm
