I may be turning into a conspiracy nut. I keep most of that stuff on dale alvin gribble so that it doesn't overwhelm this blog.
I'll tell you some of the problems I have with 9-11 but don't have room here, I'll revise this post.

7:40 PM
Military exercises on that day that removed air defences from the area.
The way the buildings fell, including bld 7 that wasn't hit with a plane. Fire fighters said on the radio, two lines would put out the fire in bld 7. Billionaire owner stated "There had been enough death that day so it was decided to PULL bld 7." PULL is a demolition term meaning blow it up, in a controlled manor. It takes days or weeks to place the explosives for a PULL. Therefore bld 7 had been pre-wired with explosive starting at least several days before, probably more. Some firefighters noticed that the towers were blown floor by floor. Billionaire dude had the insurance policy changed to include acts of terror shortly before 9-11.

[It has also been suggested that Larry Silverstein, the owner of the World Trade Center, may have benefited from the insurance payouts. Silverstein purchased a 99-year lease on the complex in July 2001. Following the attacks, he sought a $7.1billion payout, claiming that the two plane impacts were two separate attacks.[143][144] The World Trade Center also contained a large amount of asbestos that was required to be removed; some claim that the cost of carrying out this task would have been in excess of $1 billion. It has also been claimed that the office space within the building was unprofitable and the area was in need of urban renewal.]

The "Man on the street interview" .
The tiny hole in the pentagon, the same thing that brought down three or two huge buildings didn't even destroy books, chairs, computers right next to it. the lack of video tapes at the highly secured pentagon. No wreckage, well the only wreckage was carried out under a tarp by some guys.
The flight in Pennsylvania that just left a little tiny round hole in the ground, again no real wreckage.
That's just what I can remember off of the top of my head.
