NASA will attempt to set the world speed record for an air-intake engine tomorrow.

The X-43A Hyper-X is a supersonic ramjet that may lead to more efficient launch vehicles and missiles in the future.

"We are about to fly at Mach 10 - 7,000 mph - a small aircraft inflight with a supersonic ramjet which has never flown at these speeds before; it will be another world record," said project manager Vince Rauch.

Mach 1 is the speed of sound, and anything above Mach 5 is considered hypersonic flight. A previous X-43A flight on March 27 reached Mach 6.83, and set the speed record for an ...
