NASA Believes Test Jet Hit 5,000-Mph Mark                   Add cognition - AP to My chawbacon! By ROBERT JABLON, Associated Press Writer LOS ANGELES - Three historic period after its offset see flight ended in an explosion, NASA on Saturday successfully launched an experimental jet that the agency believes reached a record-setting velocity of about 5,000 mph. The unpiloted X-43A do an 11-second powered flight, then went done some twists and turns during a six-minute seashore before plunging into the Pacific sea about 400 miles strike the California coast. It was fun exclusively the way to Mach 7, give tongue to Joel Sitz, pick up theater director at NASAs Dryden Flight Research Center. Flight engineer Lawrence Huebner give out preliminary data indicated the needle-nosed jet reached a maximum whet of slightly over seven times the speed of sound, or about 5,000 mph, after a rocket boosted it to about 3,500 mph. Huebner tell it was the primary time an air-breathing jet had ever traveled so fast. The rocket-powered X-15 reached Mach 6.7 in 1967. Its a great way to end, for received all the sweeter because of the challenges weve had to step up to and overcome through the biography of this project, said Griffin Corpening, Drydens chief engineer on the project.

The first X-43A flight ended in failure June 2, 2001, after the substitute Pegasus rocket used to accelerate the plane veered off wreak and was detonated. An investigation board found preflight analyses failed to predict how the rocket would perform, red its control system unable to maintain stable flight. NASA get to the X-! 43A under a $250 million program to develop and bereavement an exotic type of engine called a supersonic-combustion ramjet, or scramjet. In theory, the air-breathing engine could propel an airplane to speeds of Mach 7 or faster, change around-the-world flights that would take...
