If you’ve ever wondered what Mach 20 looks like, check out this video of last week’s test of the Hypersonic Test Vehicle, HTV-2.

And while I think this is all kinds of cool, in the current environment it’s probably not the best use of public money.

Not that any considerations like that ever matter, of course.

UPDATE: It’s not paranoia if they really are out to get you! Here it is, proof of the massive Earth-destroying asteroid cover-up conspiracy thingy. Or not.
