The best of the bunch is, of course, an elaborate one: MH17 is actually MH370, that Malaysia Airlines flight that disappeared into the Indian Ocean. According to this theory, the plane didn’t disappear at all, “it was taken to an American military base, Diego-Garcia.”
Then it was taken to Holland. On the necessary day and hour, it flew out, bound for Malaysia, but inside were not live people, but corpses. The plane was flown not by real pilots; it was on autopilot. Or take-off (a complicated procedure) was executed by live pilots, who then ejected on parachutes. Then the plane flew automatically. In the necessary spot, it was blown up, without even using a surface-to-air missile. Instead the plane was packed with a bomb, just like the CIA did on 9/11.
The theory also notes that the passports of victims at the crash site all look brand new even though there was an explosion and a fire. “That is, the passports were tossed in [after the crash].” And, most damningly, all the victims’ Facebook pages were created in one day and the media is not showing any of the victims’ families, just the crash site.
