Likewise some of these same individuals are stating that a massive explosion (some say bomb going off) best fits the known facts (no trace of aircraft)
I still contend it's not possible to somehow rule out terrorism simply as a result of it not being publicly proclaimed
Can’t be definitely ruled out, but makes it even more unlikely than the other explanations which have been proposed, each of which are so far being classified by experts as unlikely. Fact remains, though, that the plane is gone.
