I was involved in some testing on the sled track at Holloman about 10 years
ago that approached 8000 FPS. That was very impressive at the time with
multiple sonic booms. I was looking at the video and stills of it the other
night. It's amazing what a bird will do to the sled at or near that speed!
The track at Hollomon (White Sands Missile Range)is about 10 miles long. For
this particular test the sled traveled about three miles, 11,000 feet of it
through a 184-inch in diameter helium tube, at about 9400 FPS. Helium was
used to decrease air friction and simulate upper atmospheric flight
condition. It certainly puts everything into perspective.

So like where do you think we could find the zero mass driver to pilot this
thing.. Just imagine the g forces.. This is Mach 8.5 at the 3.. It has to
make a
top fuel car be like a Yugo going uphill from a standing start. I would have
loved to have seen it just from the engineering standpoint alone. I would
not
discount this feat to quickly.. At 20 million it is a bargain, some day what
comes out of this will save our sorry asses during the next global
'disagreement'..
