Ce que vous savez pas, c'est que il y avait un autre avion, et d'autres images de l'attentat sur le pentagon qui ont été supprimées/confisquées. Et ce que je dis, c'est de source sûre, ce n'est pas du blabla de conspiration. Un autre avion suivait celui qui a explosé dans le pentagon. Même que un des témoins passait au début pour un fou, un de ces pauvres 'conspiracy theorist'. Jusqu'à ce que le pentagon confirme:

Signs of a Cover-up at the Pentagon
Frank Levi, 2002
How many times did we see the video clips of the planes hitting the World Trade Centre? It was repeated almost like a loop on every channel until the horror of the event was permanently burned into our memories.
Yet what can be said of the plane crash at the Pentagon – we heard about it soon enough, but very few images were forthcoming on the day, and the bulk of what we saw afterwards were still photos of the collapsed portion of the pentagon and a few pictures of fire-fighters attempting to extinguish the blaze. No sign of any video recordings, very few witness reports and definitely nothing to show us the event as it happened.
Have a look at the following two links – it appears the Pentagon’s security cameras failed to capture the crash on CCTV, yet a nearby hotel and a gas station had security cameras which DID manage to capture the whole event. Pretty poor security at the Pentagon – its just a wonder that no-one else is trying to attack the world’s only superpower if the security cameras on their military command centre can’t manage to film a plane crashing into the building. The FBI came and confiscated all the tapes without even having the common courtesy to give them to CNN so we could see them 56 times a day. Were they worried that we might see pieces of paper with state secrets on them flying out of the building? What exactly are they worried we might see?

Video of attack The electronic news media have broadcast repeatedly the attack on the World Trade Centre. They are perhaps the most dramatic news images since the explosion of the first atomic bomb over Hiroshima.
Now word has reached us that federal investigators may have video footage of the deadly terrorist attack on the Pentagon.
A security camera atop a hotel close to the Pentagon may have captured dramatic footage of the hijacked Boeing 757 airliner as it slammed into the western wall of the Pentagon. Hotel employees sat watching the film in shock and horror several times before the FBI confiscated the video as part of its investigation.
It may be the only available video of the attack. The Pentagon has told broadcast news reporters that its security cameras did not capture the crash.
The attack occurred close to the Pentagon's heliport, an area that normally would be under 24-hour security surveillance, including video monitoring.

NEX camera captures Pentagon crash
Security cameras at a NEXCOM-operated gas station recorded the Sept. 11 crash of a hijacked passenger airliner into the Pentagon, Navy sources have said.
The security tape, which sources said clearly shows the American Airlines jet ploughing into the building and exploding, was turned over to the FBI.
The gas station is located on a hill south of the Pentagon. Its security camera is aimed to record cars coming and going from the gas pumps. The angle of the camera gives a clear view of the side of the Pentagon where the 757 jet hit, sources said.
The tape’s existence has not been discussed publicly by military officials or federal investigators.
What exactly do they not want us to see?
Here are two abstracts of articles taken from the Daily Press:
'HORRIFIC' IMAGE STILL HAUNTS SURRY WOMAN DISASTER VIEWED FROM ARLINGTON Daily Press; Newport News; Sep 14, 2001; TERRY SCANLON Daily Press;
Abstract:
Her brother, [Keith Wheelhouse], of Virginia Beach, spotted the planes first. The second plane looked similar to a C- 130 transport plane, he said. He believes it flew directly above the American Airlines jet, as if to prevent two planes from appearing on radar while at the same time guiding the jet toward the Pentagon.
Wheelhouse's account of a second plane is unlike everything else that has been reported about the attack. Some initial reports on television said a second airliner might be headed for the Pentagon, but authorities later dismissed that. A Norfolk-based FBI agent interviewed Wheelhouse Wednesday evening.
A possible explanation for the second plane could be a plane landing at nearby Ronald Reagan National Airport. The Pentagon is between the cemetery and the airport. But Wheelhouse insists he was not confused by other air traffic.
HAMPTON ROADS WOMAN SAYS SHE, TOO, SAW PLANE FOLLOWING JET THAT HIT PENTAGON Daily Press; Newport News; Sep 15, 2001; TERRY SCANLON Daily Press;
Abstract:
Kelly Knowles, a First Colonial High School alumnus who now lives in an apartment a few miles from the Pentagon, said some sort of plane followed the doomed American Airlines jet toward the Pentagon, then veered away after the explosion.
At the same time, [Keith Wheelhouse] and his sister, Pam Young, who lives in Surry, were preparing to leave a funeral at Arlington National Cemetery, which is less than a mile from the Pentagon, when they watched the jet approach and slam into the Pentagon. Both of them, as well as at least one other person at the funeral, insist that there was another plane flying near the hijacked jet.
A follow up article to these two can be seen at this link. (From the Google cache)
Over a month later Pentagon officials finally decide to deliver a convenient story that the mystery plane WAS in fact a c-130 that flew out of Andrews Air force base and just happened to see flight 77 on its way to destruction. It followed the plane on a request from air traffic control. If this is true, surely you’d think that a fighter from the same base could have intercepted the plane instead of having to ask a c-130 that just happened to be in the area to have a look?
All of this certainly adds a lot of fuel to the popular theories that the planes were being flown by remote control, especially now we have evidence to suggest that an unknown plane or flying object has been sighted at the WTC, flight 93 and now at the Pentagon.
