Mach 10 ScramJet

One more step towards the day when we spend more time at the airport than actually in the air.

They call it a "scramjet," an engine so blindingly fast that it could carry an airplane from San Francisco to Washington, D.C., in about 20 minutes -- or even quicker. So fast it could put satellites in space. So fast it could drop a cruise missile on an enemy target, almost like shooting a rifle.

Mach numbers signify how many times faster than sound you're going. This flight of the X34 is expected to reach some 7,200 miles per hour, which is nearly ten times the speed of sound.

The speed of sound isn't an absolute number because it varies somewhat with temperature, humidity and other factors. Seven hundred and fifty miles per hour is a fair enough estimate.

Go read it. Cool stuff. Thanks to Kyle the Nog-Warden and Carl (who has deep nog-secrets) for pointing this one out.
