It was fast huh? hard to imagine that kind of speed. I think that tv programe you watched must be old though because the X-43 did finaly get a record of mach 9.8.

By the way, the current Boeing scramjet test aircraft, X-51, first flown last year goes mach 6 but it can go for much longer burns, it has the record at 140 seconds compared to the X-41's 12 seconds on its record speed flight.

the old sr-71s speed is still classified. but a pilot at a seminar where i live said that if you shot a 30-.06 ( ammo from a M1 garand) in california at the same time a 71 flew by....the 71 would beat the bullet to washington DC by 5 minutes....the given is the 30-.06 round would not lose any energy. the muzzle velocity for that round is ( depending on the bullet) 3000 to 4000 feet per second. and that was from a plane made in the 50s.... i think they are not giving you the real upper end of this ac.... i would bet it is way higher.

Sorry? What for? The X-43 set the current unmanned aircraft speed record in 2004.

A test flight of the 'world's fastest plane' has ended in disaster after the vehicle crashed into the Pacific Ocean.
