David Weinberger blogs about the latest in denial theology: the Pentagon wasn't hit by an airplane because the author of the pages he points to (I refuse to point to these pages) is too stupid to understand how the Pentagon was hardened to withstand impact and how the plane practically vaporized. It's disgusting that anyone would try to establish a conspiracy theory given the number of deaths involved and the number of eyewitnesses. You can read accounts all over the Net by individuals who saw the plane in question, knew people on it, or heard the sound of the plane hitting the Pentagon. There is no question whatsoever what happened. Mr. Weinberger knows someone who saw it happen. Conspiracy theory is rarely amusing, but never has it so clearly demonstrated total ignorance of basic physics.
