I had a look at the main points and once again wondered at the stupity of people who believe in conspiracy theories like this.
First off the Pentagon attack. This has been done to death. There was a plane, it hit the Pentagon. Anyone who doesn't believe me. Do a google for Pentagon images. There are plenty of aircraft parts in various pictures available. When an aircraft hits hard there isn't much left. Aircraft are not ships. They are lightly built and quite fragile.
Secondly the WTC, secondary explosions? Why? When you just flew two jetliners into the towers. Their main platform is that firemen heard 'explosions' inside the buildings as they were collapsing. I could be wrong but I imagine a collapsing building might make a lot of sounds like explosions. In any case there are several intelligent suggestions as to why they fell from professional architects and engineers unconnected with the CIA or Mossad. Again google is your friend.
Need I go on...............
Finally flight 93. It landed at Cleveland apparently. Of course it did.

Again the lack of wreckage fuels this nonsense. When a plane hits the grounds at 580 mph vertically down. It goes a long way down and not much is left of it or the passengers.
Another conspiracy theory says it was shot down.
The video is BS from start to finish.
