Im afraid Im having a monstrous debate - unfortunately its in swedish. In short, its more or less one person, Heiwa, who claims AA77 didn't hit Pentagon and from what I can gather I think he gets most his material from Pilots for 911 truth.
Among his claims have been that the NTSB didn't investigate the crash - which he alleged was in violation of international laws, he claimed that no aircraft debris was found at the Pentagon - photos are either planted, altered or showing something else. This thread was induced by his latest claim "No witness saw AA77 hit the Pentagon - since the plane wasn't painted". I remembered that a lot of witnesses said they saw "American Airlines" painted on the body, so hence this post.
Its very educative for me, it has made me learn more than I could ever imagine about FDR's, the NTSB and its mandate, same with the FBI.
The thread is located
here, and I am using the same nym over there as here.
The guys homepage can be found
here (in english). He is deep into a Estonia-conspiracy as well, but thats more understandable given his background as Naval Architect and Marine Engineer.
