MFSC reported that the first Space Shuttle engine tested for flight acceptance had "passed with flying colors" a 520-second endurance test May 12 that simulated launch conditions. Scheduled for use on Columbia, this engine would undergo electrical and mechanical checkout before formal acceptance. The tests began April 25 with 1.5-second ignition-test firing, followed by a 100-second calibration-test firing May 2. After formal acceptance, the engine would go by truck to KSC for installation. The other two of the cluster of three Rockwell-built engines to be used on Columbia were at Space Technology Laboratories for the same series of tests. (MSFC Release 79-45; NASA Release 79-68)
