Thanks for posting this. These miserable people drive me crazy, a d unfortunately their numbers include some prominent people.
That kind of science and engineering is above my pay grade, but I am an Occam’s razor type. Think, for a moment, of all the stuff you have to believe to believe in this conspiracy( same with the moon landing conspiracy) What about United 93? What about the Pentagon? Who were these 19 hijackers if they weren’t the hi jackers? You have to believe that everybody from Bush and Cheney to Rudy Guiliani and the 911 widows were in on a conspiracy theory together. Human nature just isn’t that way.
Physics is big on Occam's razor, too. But hey, if you don't "do" physics, then by all means, don't consider it.
