Just a few minutes ago, Anderson Cooper stated that TWA 800 was SHOT DOWN! Yep he said it. Perhaps a little slip of the tongue? We know that plane was shot down just like this Malaysian plane was.
Surface to air missiles leave thermal signature and American spy satellites would spot it right away if SAM was fired in this high tension region. Seems it was not. Unlike TWA 008.
What else might happen:
it was shot by air to air missile - either from Ukrainian or from Russian airspace.
Remote controlled to crash - a role originally assigned to MH370 but never played out.
Towelheads lost control of hijacked plane due to passengers pulling Todd Beamer on them (United 93)
