No chance at all that it wasn't a plane. All the crap that flash showed is easily explainable. The funniest part was him comparing that still frame from the camera near the pentagon where you can see the leading edge of something just before impact, and him comparing it to a photo of a plane sitting on a runway. News flash: Shit looks way different at 350-550mph (depending on what account you believe) to a still camera than something sitting still. I tried taking pics of some of indy type cars at the Long Beach Grand Prix one year from behind the concrete barriers of the straightaway. At less than 200 mph, it was near impossible for me to even get one in a frame, and when I did, it didn't even look like a car. What do you think a jumbo jet would look like at twice or more that to an immoveable camera not using high speed film?
You can make anything look fishy if you pick and choose what to report, especially something so widely reported and photographed. People just love conspiracies, and they'll cling to shit like this because they are retarded and easily led around by the nose. Oh yeah, crop circles are real too. Dopes!
