Description : (La description de cette image n'existe qu'en anglais)

NASA's HIDEC (Highly Integrated Digital Electronic Control) F-15 aircraft nears the runway after a flight out of NASA's Dryden Flight Research Center, Edwards, California. The last project it was used for at Dryden was development of a computer-assisted engine control system that lets a plane land safely with only engine power if its normal control surfaces such as elevators, rudders or ailerons are disabled. The flight control system helps the pilot control the engines to turn the aircraft, climb, descend and eventually land safely by varying the speed of the engines one at a time or together. The HIDEC F-15A, built as the number eight prototype (Serial #71-0287), has now been retired.
