2. Marvin Bush, related to the president, was head of security at the WTC just prior to 9/11
3. No steel framed skyscraper has ever come down solely due to fire prior to 9/11.
4. People exiting the WTCs on 9/11 heard explosions, so there must have been explosives planted in the buildings.
5. the collapses alone cannot by themselves explain the pulverization of all the concrete in the WTCs

7. The fires in the WTCs were small and spread out.
9. There was molten STEEL in the remains at GZ, proving the use of THERMITE.
Topic=WTC 7

2. Larry Silverstein told the Fire Captain to "Pull" the building, meaning to have it brought down by Demolition.
3. Larry Silverstein made hundreds of millions off the collapse of this building and the twin towers

Topic = Pentagon Attack
1. American Airlines Flight 77 never hit the Pentagon.
2. The downed light poles were planted, like the plane parts, by the USG who were behind the attacks.
