I hate to read you are one :p

This is the first time I read the claimn that AA11 was supersonic. According to
Wikipedia, the aircraft was "traveling at about 404 knots (465 mph; 748 km/h)".
Speed of Sound at 20° is 1,236 km/h = 768 mph. That "is nearly independent of pressure or density for a given gas". So it would appear that you are quite wrong here.

I would think that after 9/11, New Yorkers would be much more alarmed by the sight of low-flying airliners that before 9/11. What do you think?

Can you cite where in the "official version" this claim is made - that ONLY a handful of firemen and a camera man spotted the first plane? I was so far under the apprehension that various media outlets already had callers on the phone and live on the program that described seeing the first plane even before the second plane hit. It seems that, again, you are very wrong here.
Obwon wrote:Which is pretty absurd. Notice that they appear to turn to look at where they supposedly hear the sound of the jet. But, depending on the height of the aircraft and it's speed (supposedly supersonic at that point), by the time they hear the sound, the air craft would be 3 seconds advanced from over their heads. That puts it behind the telephone building already. Unable to see what it is, no less it's trajectory, what is there to prompt the cameraman to quickly focus on the WTC? Surrounded by tall buildings everywhere, he can have no clue that there will be anything for him to see anywhere.
Hmmm. I call conjecture. We had a couple or three military air bases pretty close to where I live, and we spotted Phantoms, Harriers, even Starfighters, more or less daily. I can't say what speed maximum they were flying at when they passed low over my home town - slower than Mach1 certainly, but faster than 500 km/h no doubt.
I can tell you that we never had trouble finding the source of the noise in the sky.
True, would be trickier with tall buildings in the way like in Manhattan, but impossible? Hardly.
Obwon wrote:That brings us to the impact itself. Had the plane been completely and perfectly perpendicular to the building face, some sort of penetration, of the type shown, might have been possible. But that wasn't the case. The aircraft was not perpendicular to the building face, the nose of the craft was slightly below and to the west of the tail. Thus, when the nose met the resistance of the building face, the rest of the craft, supported and resisted only by air, should have rotated quite rapidly in the direction of the smaller angles.
Thus the aircraft should have "broadsided" the building, with the result of leaving a huge portion of debris outside the building to be taped raining down to the streets below. My guess is that someone able to work up the figures, will soon be releasing their data, showing how the aircraft should have behaved on impact.
It's been done before, using advanced dynamic simulation tools. Purdue University, if I remember correctly. Result was that plane would penetrate staright into wall as observed. I think your private, probably uneducated imagination here is shaped not by physical reality but by other influences.

I'd rather you go to actual sources of such information, I believe PFT is not in particularly high regard around here (meaning: Most of us are aware of several gross distortions of reality committed by the rank and file of that group).
