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.
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.
Hmmm. . . .must not have had a J-4 copper jacket. Thinking about it, most rifle cartridges struggle to break the Mach 3 barrier, and they're saying this classified flying thingy was going almost seven times that fast! And that's only what DARPA will publically admit to! Fantastic. Now, how do we get this technology to Hornady? I think it would be great to not have to dial in elevation on my scope to blast a doe at 3,698 yards.
