I argue speed because speed is dependent on altitude - higher altitude equals faster speeds, and wikipedia uses the speeds you quoted as "cruising speed." Point being that high altitude cruising speed is higly unlikely to equal similar speed close to the ground.
Bear in mind that max speeds are always quoted as being in level flight, not at the terminal points of dives.
At sea level, at a temperature of 15 °C (59 °F) and under normal atmospheric conditions, the speed of sound is 344 m/s (1225 km/h or 761 mph).
[source]
So, you are trying to tell me these jets were doing close to the speed of sound when they hit the towers - blatantly false because any video evidence (of the 2nd jet for instance, obviously is travelling nowhere near the speed of sound, and yes, I've been to some of the world's top airshows and am fully aware of what the speed of sound looks like at low level.) The lumbering jet that hit the second tower was doing nowhere near the speed of sound, I would think it was doing the usual speed in a low altitude configuration, ie, about 230 knots or less, and we also should know, these jets have low landing speeds, under 200 knots.
Please re-read what I wrote. I said nothing about "close to the speed of sound", I said that the max quoted estimated speed (950kph) was only Mach 0.77.
Why would it be doing a low speed? Because the hijackers were worried about damaging the plane? I'm sure you're aware that distance and size can alter our perceptions of speed considerably. While it's entirely possible that it wasn't doing 950kph, I seriously doubt the plane was moving slowly.
I notice boeing doesn't post a "maximum speed," it is irrelevant in terms of airlines (load, thrust, range, cruise, etc, being more important.)
But I do find this:
Boeing 767 Maximum Speed: 583 mph [source]
Whoever wrote that obviously took Boeing's max cruise speed and interpreted it as maximum speed.
So your max quoted above of 800-950kph is plainly impossible as this would be maximum speed at altitude, ie, the only place where true maximum speed would be attained.
You keep saying that, but you *still* have not provided any evidence of this; let's not forget the issue of a dive either...
(Incidentally, there are a number of reports of World War 2 fighters going transonic in dives, yet their maximum speeds were only in the region of 650kph.)
Where? The NIST faq is shown to be not worth the paper it is written on (explain concrete pulverizing to dust, even explain mushrooming.) Explain the woman alive in the impact hole (which you still haven't managed to do.) Explain the firefighters reports of being on the impact floor. All directly in contrast to the NIST faq, the ULTIMATE authority on these events.
Again, ask the experts. I still don't see the point about the woman. I have seen pics of the second tower with a great hole in it, and no fires.
Incidentally, this file makes fascinating reading - it's got a great deal on the impact and the ability of the buildings:
Engineering
So you are not disagreeing that on impact the jets were in level flight. I speak the 2nd jet because I saw this with my own eyes (tv). It made a slow turn. A turn at the speeds you describe, once again, is something an experienced pilot would have a problem executing in an airliner but this is a cessna pilot, obviously a natural ace in your estimation.
What makes you think the pilot was a Cessna pilot? There's evidence that he tried to rent a Cessna, but in fact he was a licenced commercial pilot with instrument ratings. How many hours do you need for a commercial licence?
On the hit to the pentagon and astroturf: I did find info on this and I don't feel like searching for it again; simply, rules of ground effect and plain pilot overload at that speed at low altitude make this a difficult maneuver for even the most experienced pilot.
You mean, when a pilot intends to survive...
What does ground effect have to do with it? Read this - it's very enlightening: http://www.aerospaceweb.org/question/conspiracy/q0274.shtml
So, the building mysteriously vapourised due to the impact of the jet and floors collapsing. Do you really think it would be so neat and leave such a neat pile x 2 buildings?
Neat? Eh? Where'd you get that one from? Loose Change? The collapse was anything but neat!
Do you really have any clue what you're talking about. This is not a sprung elastic band; it is a 110 story building, the height of engineering. But no, pulverised to dust. Thousands of tons of steel and concrete a smoking hole in the ground. Fairy dust never had it so good.
Potential energy. Gravity. Read up on it.
Nope, it was identified as a Rolls-Royce RB211.
Please point to one link where this was verified.
Here's a very nice, thorough link: http://www.aerospaceweb.org/question/conspiracy/q0265.shtml
And another, debunking Loose Change: http://www.ccdominoes.com/lc/lcg2.html
Chicago's Museum of Science and Industry displays the Pratt & Whitney JT8D. These photos show that JT8D matches the Pentagon engine photographed at the crash site.

Unfortunately, they state that these engines were used in the A-3 Skywarrior. That's completely incorrect. Can't they even get that simple fact right?

And here you are posting speeds again, speeds that are plainly impossible at low altitude especially insofar as my max speed quoted above.
Proof! Evidence!
Also, I'm still waiting for that theory. Or would you like me to draw one up?
