NASA Testing Supersonic X-51A Jet Tomorrow
First time accepted submitter littlesparkvt writes "The NASA and the Pentagon's experimental aircraft could go from NY to London in about an hour. With a cost of 140 million dollars USD. During the test the X51-A will reach speeds of 1700 meters a second and climb to an altitude of 70,000 feet."
Still costs less than a F22 Raptor http://en.wikipedia.org/wiki/Lockheed_Martin_F-22_Raptor
m is metre moron
It's an American missile. Why would they be talking in weird foreign measurements? I mean, "metre"?! R before E? Who spells like that? Sounds like some kind of cheese-eatin' surrender-monkey socialist kind of measurement. Certainly not the kind of measurement that freedom lovin' people from the Good ol' USA would use.
So there you have it. 1700 miles per second. That'll put the fear of God into those godless commies.
(I was going to mark my original post as sarcasm but I thought, "Nah. People will get it.")
Above Mach 5 or so you have to start considering different physics about the air flow.
