Hypersonic scramjet goes 3000+
Anybody else sentimental for the time when news like this was a big deal?
I know it's just a weapon, now, not a stepping stone to a better future, but it rekindled a spark in me - a reminder of when the future was all rockets and moon launches and the latest and greatest spaceships in the world and the trickle down to a fantastic way of life. 3,000 mph at 60,000 feet: Experimental Air Force aircraft goes hypersonic - Washington Times "LOS ANGELES — An experimental, unmanned aircraft developed for the U.S. Air Force went hypersonic during a test off the Southern California coast, traveling at more than 3,000 mph, the Air Force said Friday. The X-51A WaveRider flew for more than three minutes under power from its exotic scramjet engine and hit a speed of Mach 5.1, or more than five times the speed of sound."

I'd consider that a "missle" instead of an "aircraft"...
If it intended for military bombing or satelite attack, back in WW2 there was a concept project for a plane which would skip upon the density of the upper statosphere. Amerika Bomber - Wikipedia, the free encyclopedia

Meh. A well prepped 944 can do that.

3,000 mph?
 Is this news because it was unmanned?

Speed of sound varies, but is usually taken at 330m/s
1m/s= 2.237mph 330m/s= 738.21mph(mach1) so mach 5 = 5*738.21 mach 5= 3691.05mph

The speed of sound varies with altitude.
File:Comparison US standard atmosphere 1962.svg - Wikipedia, the free encyclopedia Seriously - Way cool. A breakthrough for this technology. They getting close to X-15 speeds. Very impressive for an air-breathing engine. But then, I'm a serious aerospace technology geek (and former rocket scientist - guidance system division). |

Unmanned?
What's the fun in that?
