Puh-leeze. It fails just about every basic logical test. Especially the leetle detail about how such a massive conspiracy could be kept leak-free for five years after it happened.
Believing that those buildings came down due to fire, when there are pictures of people standing in the gaping maw left by one of the planes shortly after the fire died down, is insanity.
Like I said - you no longer can tell apart sanity from conspiracy.
I don't think they held open job interviews to do the deed. If you've never seen a true believer who can suspend judgment for a cause, go look in the mirror.
