NASA Believes Test Jet Hit 5,000-Mph Mark                   Add lore - AP to My chawbacon! By ROBERT JABLON, Associated Press Writer LOS ANGELES - Three long time 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 by means of some twists and turns during a six-minute seashore before plunging into the Pacific naval about 400 miles strike the California coast. It was fun all(prenominal) the way to Mach 7, give tongue to Joel Sitz, pick up conductor at NASAs Dryden Flight Research Center. Flight engineer Lawrence Huebner babble out preliminary data indicated the needle-nosed jet reached a maximum festinate 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 state it was the foremost 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 true all the sweeter because of the challenges weve had to step up to and overcome through the tone 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 measure up Pegasus rocket used to accelerate the plane veered off rule and was detonated. An investigation board found preflight analyses failed to predict how the rocket would perform, blemish its control system unable to main tain stable flight. NASA attain the X-43A ! under a $250 million program to develop and trouble 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...
