 מצורף קובץAn unpiloted NASA (news - web sites) X-43A jet attached to the nose of a Pegasus rocket booster takes off under the wing of an Air Force B-52 at Edwards Air Force Base, Calif., Saturday, March 27, 2004. Once aloft, NASA then launched the experimental jet, capable of reaching speeds approaching 5,000 mph. The X-43A made a 10-second powered flight and then went through some twists and turns during a six-minute glide before it was allowed to plunge into the ocean.
