Even if it was not really an inside job, it's something they allowed to happen.

How on Earth did two 9/11 hijackers passports' survive Flight 11's plane crash on September 11?

Google it. Al Suqami's passport was found by an anonymous person who handed it into the police, the same day despite a 6-month clear up. Also, on the SAME day, Atta's passport was found. We're told that the plane crash instantly vaporized all on board hence none of the hijacker's bodies, the "undestroyable" black box, yet two paper documents survived.

There is just too much evidence now that suggests an inside job: the fact that most of the 'hijackers' are still alive, the fact that no jets were scrambled in time; that no significant plane debris was found at the pentagon site (planes do not vaporize!); that the buildings seem to be demolished, especially building 7; that jet fuel cannot melt steel, even though molten steel was seen; that the first responders heard explosions within the buildings before they collapsed etc...

How did the BBC know in advance that Building Seven would collapse? The fact that it was announced in advance is strong support that the flow of information on this tragedy was being controlled.

Were the people at the BBC the only people privy to this information? Probably not. Larry Silverstein was the leaseholder of Building Seven. In a 2002 PBS documentary he talked about how he discussed the Building Seven situation with the fire department and how the decision was made by that department to "pull" it. Well, there is one problem with his testimony that you may want to consider. It takes about a week to rig a building with explosives before you pull it. So are buildings constructed with built-in explosives just in case they need to be blown up in a hurry? Building Seven went down that same day. Whoops! Watch Larry's testimony from the PBS documentary here in this short clip.

-WTC leaseholder Larry Silverstein admitted that building 7 was pulled down by a controlled demolition:

He changed his story the next day.

-Official version claims the towers collapsed due to 'pancake effect', meaning the floors came detached from steel girders and fell on top of each other, collapsing the tower. If that's the case, why weren't any of the (core column) steel girders left standing?

-Pictures show smoke coming from the basement seconds before the plane hits. People (including firefighters and employees) also heard explosions from below the towers, moments before the plane hit. PEOPLE WERE KILLED AND SOME SERIOUSLY INJURED IN THE BASEMENT.

-Pictures show steel girders with diagonal cuts in the them. This is exactly how controlled demolitions bring down buildings.

-Designers of the WTC say they were built to withstand MULTIPLE impacts from such an aircraft.

-Official version states the plane that hit the pentagon 'vaporised' which is why very little traces can be found. Yet they managed to find DNA to identify all of the victims on board. Furthermore the building didn't 'vaporise' in any way. What type of plane vaporises, leaving the building and human DNA relatively undamaged.

-The passport of one of the hijackers in the aircraft was supposedly found in the rubble at the WTC. It's clearly impossible for any personal effects to survive the impact and explosion, therefore it must have been planted.

-All CCTV from around the pentagon has been removed and never released. Why do that if there is nothing to hide? 86 CCTV cameras no airplane???
