Thierry Meyssan - French Conspiracy Theorist Claims No Plane Hit Pentagon
This was posted to a government site in June, so it is a bit old, but I thought it was worth mentioning for those interested. It comments on Pentagon and WTC 'conspiracy theories'.

In conclusion, Mr. Meyssan's book ignores obvious facts, makes sweeping, totally unfounded allegations, and employs spurious logic to try to explain away facts that he apparently finds inconvenient. As the French newspaper Liberation said, the book is "a tissue of wild and irresponsible allegations, entirely without foundation."
Finally, The 9/11 Commission Report states that on September 11, air traffic controllers at Washington's Reagan National Airport instructed a C-130H cargo plane that had just taken off from the airport to try to follow the plane that had been spotted on radar as heading toward Washington. According to the report, "The C-130H pilot spotted it, identified it as a Boeing 757, attempted to follow its path, and at 9:39, seconds after impact, reported to the control tower: ‘looks like that aircraft crashed into the Pentagon, sir.'"

In sum, hundreds of people on nearby roads or in nearby buildings saw a large passenger plane hit the Pentagon and, as the above eyewitness testimonies demonstrate, numerous people specifically identified it as an American Airlines plane.
