Among the most important proofs that no Boeing 757 hit the Pentagon is that the official trajectory — barely skimming the ground at over 500 mph and taking out a series of lampposts — is both aerodynamically and physically impossible. I have argued in the past that it is aerodynamically impossible because ground effect would not allow a 757 flying at that speed to get closer than 60 or even 80 feet to the ground, where 80 feet is higher than the Pentagon at 71 feet is tall. And it is physically impossible because the effects of a plane flying over 500 mph hitting a series of stationary lampposts would be the same if the plane had been stationary and hit by lampposts flying at over 500 mph: they would have ripped the wings over, where the jet fuel stored in them would have burst into flames and the plane could have cartwheeled across the lawn. While I regarded my arguments as impeccable, I was faulted on the ground that “ground effect” would not make it impossible for a Boeing 757 to barely skim the ground, which led me to look further into the matter and discover that I had the right concept but the wrong name, where it is better described as “downwash”, as the technical study that follows explains in detail. That was a benefit from participating in the thread on Truth and Shadows, “Gage concedes his entry into 9/11 Pentagon quagmire has been divisive”. But some of those who were participating displayed scant familiarity with the evidence, which Dennis Cimino and I have recently surveyed in our study, “Relections on the Pentagon: A 9/11 Photographic Review“. It also became clear that some students of 9/11 do not know the basics of “No Plane Theory” (or NPT, as it is sometimes called), which maintains that none of the official 9/11 aircraft–for Flights 11, 77, 93 and 175–actually crashed on 9/11. It does not mean that no planes at all were involved on 9/11, where the trucker buddy of a friend of mine from JFK research had told him that he had been in front of the Pentagon and watched as a commercial carrier flew toward it and then swerved over it, as I have explained in many places.
