NASA plans to try to set a world speed record for jets on Monday with the flight of a pilotless vehicle that culminates a decades-long research program into hypersonic flight.The craft, the X-43A, is powered by a rocket booster dropped from a modified B-52 bomber. In a short dash above the Pacific, it is to use its experimental scramjet engine, which is expected to push the craft to almost 7,000 miles an hour, or 10 times the speed of sound.
Yes but this aircraft is only as big as a kayak.
