I was aware of the plane crash into the Empire State Building; that is a solid brick and mortar building totally unlike the WTC towers, but that is another topic of discussion. I will speak with the co-workers to have them tell me what they saw. What about the thousands of people who were standing on the ground, a block or two from the WTC towers, when the 2nd plane hit? I suppose that the speed of a jet wouldn't allow definitive i.d. of it, and TV video of it later on could cause their memory to be altered. I watched the camera feed from the Empire State Building that morning and saw what looked like a relatively slow moving aircraft moving from west to east, then the explosion, and I thought at the time, "Wow, some small plane loaded with explosives just hit the tower!", but it was the jet moving from SSW to NNE, at a high speed, that gave that illusion. I will check out the other aspects you have reported. The pilots saying it wouldn't be possible to fly the plane the way it supposedly was has me the most curious.
