I've wondered that, too. What happened to the 4 planes? He tried to tell me the Trade Center was (at least partially) blown up. If terrorists or secret Israeli cabal were blowing them up, why fly airplanes into them? And if they didn't, why did people SEE PLANES HIT THEM?

Of course there's no arguing with crazy people. I'm a contrarian, and a Lefty, but I'm not a crazy person. :)
