DARPA, the Defense Advanced Research Project Agency, has made public its best guess about what might have caused its unmanned arrowhead-shaped Hypersonic Technology Vehicle (HTV-2) to suddenly lose contact and crash in the Pacific just a few minutes after slicing through the sky at Mach 20 last August: it was going so fast its skin peeled off.
Sounds like it would have been a fun ride, until the skin peeled off the aircraft. I didn't even know this could happen. This aircraft peeled like a banana at mach 20.
It turns out that tearing through the atmosphere at 20 times the speed of sound is bad for the skin, even if you're a super high-tech aircraft developed by the government's best engineers at its far-out research agency.

I'm just curious as to what Mach 20, 1000MPH per Mach right?
I hope I can get tickets on the next flight, seems fun.
Okay got it, 21,000MPH, 20X the speed of sound, crazyedit on 23-4-2012 by AK907ICECOLD because: (no reason given)edit on 23-4-2012 by AK907ICECOLD because: Added mach info per google
Its 761mph...the speed of sound
mach 20 = 15 224.141 mph
google. Works wonders.
