Are you asking if planes slow down in a dive because the air gets denser?
No they don't slow down, that is why we used to use dive bombing against enemy ships in WWII. The inertia of the diving aircraft was passed to the bomb allowing it to penetrate structure that it would otherwise be unable too.
1) How do the building fall at free fall speed???
2) What happened to Building 7 that was not hit by the planes.
3) What caused the 3 weeks of unbelievable temperatures in the base of the 2 buildings?
4) The nano thermite residue that was found, where did it come from?
5) Why do the areas hit correspond exactly with the floors that had special maintenance in the months before?
A friend was wondering how fast the RNZAF 757 is going during its high-speed pass at airshows (as per this YouTube video):
He was wondering about 250kts but I thought it was more like 300-350kts. Does anyone here know what speed the guys are doing?
Aside from videos on the 'net, I've seen the display at a few Avalon Airshows and it always looks & sounds fantastic!
A compatriot was the guy that helped develop the display, and I seem to remember him saying they did it at Vmo, which I understand is around 340kts.
"I was the captain of that particular shot, filmed during a Squadron open-day a couple of years ago. It's part of a routine that has been performed over thirty times at various airshows and practices around the world including RIAT Fairford 2003, Kemble 2006, RAF Waddington 2006, Warbirds Over Wanaka 2004, Avalon 2005.
The low pass is flown into wind at 350 knots (indicated) and 100 feet above the runway. It's a 2g pull up to between 45 and 55 degrees nose up pitch (although there has been higher) and the zoom climb ends at an altitude between 8000 and 10000 feet depending on the type of pull up used. The sequence does not end with a loop as some of the readers speculate, but in fact with a 60 degree wingover at around 220 knots. It is easily possible to enhance this maneouver with a steeper climb and bank but there is no need - it is spectacular already, and safe."

DON'T HOLD YOU BREATH.
There IS none. I'm sure there is a speed where an aircraft (767) will break apart but i doubt that 510 knots it it. Probably close to 800-900. But then, you'll probably see the motor's come off first, not the fuselage break up. There is a certain amount of safety thats build in to allow the aircraft to exceed the "normal' limits of the frame. Like a submarine. It's built for a "MAX" depth but can go deeper. It just has a greater risk of implosion past a certain depth.
There is a report of the PSA 737 breaking up when it crashed in San Lois(sp) Obispo (the PSA flight that was brought down by a disgruntled employee as it broke the sound barrier on the way down (720+).
I'm sure that a 767, full throttle, could go 510+ without breaking up, at street level.
The "9/11'ers" will never be satisfied that a bunch of religious fanatics caused the crashes. Did the the US know it was coming? Well, they for sure had info that Al Qaida wanted to use airplanes as weapons. Did they do anything about it? NO.
Just like the Brits new Japan was going to attack the Hawaiian islands but they didn't tell the US? NO! Cause they NEEDED us in the war or they were going to be over run by the Nazi's.
Was it missiles? NO. It was airplanes. With people on board who were ALL killed (I knew one of them). No, they are not held in some "camp". They are all dead and the parts they could find are buried.
We have more pressing things to worry about like how quickly TPAB are taking away our civil liberties.

The 9/11 truthers pretty much lost me when they got caught with their hands in their pants early on showing misleading pictures and presenting falsified data to prove their theories. The pics of the pentagon taken from behind a rise (very small knoll?) that conveniently excluded wreckage of the plane and claimed: Where is the wreckage?
So .... some anonymous person on the Youtubes named "roderm" claims the low-speed pass was at 500 knots and you automatically believe it?
I wrote the owner of this video. (757 low pass) A aeronautical video company in new zealand, we discussed it, and we both came up with 450 + in level flight as a minimum.
