16 /PRNewswire/ -- NASA's X-43A research vehicle screamed into the record books today, demonstrating an air-breathing engine
can fly at nearly 10 times the speed of sound.
NASA budget documents also indicate the agency is very interested in continuing the X-43 test program, which is aimed at developing an air-breathing engine
capable of propelling an aircraft or spacecraft at speeds greater than 3,500 mph.
As part of its mission to open new frontiers in aerospace, The Boeing Company has teamed with Allied Aerospace to develop the X-43C, an experimental aircraft designed to use innovative air-breathing engine
technology to attain hypersonic speeds previously achieved only by rockets.

Although NASA's X-43A and other hypersonic airplanes uses air-breathing engines
and fly much like 747s, there is a big difference between ripping air at Mach 10 (around 7,000 mph) and cruising through it at 350 mph.
