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.
