What makes more sense is that the invaders, Russia, wanted something to look like a false flag. Another possibility is that it was an accident. Fighter pilots probably couldn't see what type of plane it was, and a bunch of small-time think tanks/NWO conspiracy knobs are trying to use the mayhem to recruit suckers into their cults.
"Another possibility is that it was an accident." it's almost obvious it was an error on rebel side. there is no way any side would have wanted their hands dirty with murdering hundreds of europeans - that's just ludicrous.
rebels were regularly downing ukrainian airplanes and just minutes after downing MH17 Strelkov reported and russian media retranslated that rebels have shot down another ukrainian AN26. except that was not AN26. pretty fucking huge clue, isn't it?
