Jean-Pierre Desmoulins worked for 15 years as an electrical engineer, systems and industrial computing fields. He is now a professor, and in 1996 founded a multimedia department at the university he works for in France. He also holds a private pilot's license. After the 911 attacks in the U.S.A., Jean-Pierre became convinced there was more to the picture than told through official versions. Thus, he began his own research, focusing specifically on the alleged crash of American Airlines Flight 77 into the Pentagon.

Jean-Pierre’s approach is rational. He examined facts and tried to imagine all possible scenarios, and used critical analysis to weigh arguments for and against each possibility. He first published his thoughts on a Web site in September 2002. This Web site, and successive versions available online, follow the path of his research from the beginning. Jean-Pierre says that, like many researchers who studied this crash, he was pushed to consider seemily-odd theories because he took pictures of the crash scene for evidence, and realized later that the facts infered from those pictures violated laws of physics, capacities of planes, or that they implied a vast conspiracy. After much study, Jean-Pierre has demonstrated, ab absurdo, that some of the most popular images on this crash, such as the "cctv camera frames" or the "red letter debris pictures" are frauds.

After examining the evidence, the scenario Jean-Pierre now proposes as the most probable is that American Airlines Flight 77, a Boeing 757 with around 60 people onboard, crashed into the west aisle of the pentagon on 911. Jean-Pierre believes that the plane was either piloted by hijacker, Hani Hanjour, or it was remotely piloted with a technology like “Global Hawk,” but has no facts to prove either hypotheses. He speculates that some precise eye witnesses accounts, damage reports or pictures inside the pentagon, along with the fact that pictures of this crash have been hidden or faked, makes it highly probable that this plane had been loaded with a warhead, like an anti-bunker hollow charge, a depleted uranium "penetrator,” or a "broach" technology bomb, which is the combination of both.
