318. 148F (Busy Stepson), 17 Jan 67, Response Mode NA, Flight Phase 2.5: Flight was
     norm.al except that reentry vehicle failed to separate.
344. 81F (ABRES/AFSC), 27 Oct 67, Response Mode 4T, Flight Phase 1: Although
     various anomalous events occurred early in flight, the missile appeared to follow
     the intended trajectory till about 24 seconds. Diverging roll oscillations actually
     began about 21.4 seconds, and pitch and roll stability were lost by 24.8 seconds.
     By 27.9 seconds, the vehicle was tumbling about 6.5 degrees per second in pitch
     and yaw, and 12 degrees per second in roll. By 30 seconds, the vehicle lost all
     thrust and began to break up. Fuel cutoff and destruct were sent at 35 and 39
     seconds, respectively.        •

358. 95F (ABRES/AFSC), 3 May 68, Response Mode 5, Flight Phase 1: Immediately
     after liftoff the telemetered roll and yaw rates indicated that the missile was
     erratic. During the first 10 seconds of flight the missile yawed hard to the left. It
     then began a hard yaw to the right, crossed over the flight line and continued
     toward the right destruct line. Shortly thereafter the missile apparently pitched
     up violently and the IIP began moving back toward the beach. The missile was
     destructed at about 45 seconds when the altitude was about 14,000 feet and the
     downrange distance about 9 miles. Major pieces impacted less than a mile
     offshore, indicating uprange movement of the impact point during the last part of
     thrusting flight.
364. 5104C AC-17 (ATS-D), 10 Aug 68, Response Mode NA, Flight Phase 4: A normal
     parking orbit was achieved, but when Centaur restart was attempted, thrust could
     not be maintained because of inoperative boost pumps. Frozen H 20 2 line was the
     apparent root cause.
365. 7004 SLV-3/Burner II/Agena D (AFSC), 16 Aug 68: Response Mode 4, Flight
     Phase 3: Atlas performance was norm.al. The vehicle failed to achieve orbit
     because th~ protective shroud surrounding the second stage failed to separate.
368. 56F (ABRES/AFSC), 16 Nov 68, Response Mode 4T, Flight Phase 2.5: Flight was
     norm.al through SECO. The missile then lost attitude control, executing a hard
     yaw rate tum throughout and beyond the vernier solo phase.
372. 5403C AC-20 (Mariner 6 Mars), 24 Feb 69, Response Mode NA, Flight Phase 1:
     Early Atlas BECO due to staging accelerometer failure was compensated for by
     extended Atlas sustainer and Centaur burns. Mission was successful.
379. 98F (ABRES/AFSC), 10 Oct 69, Response Mode 4, Flight Phase 1: The missile
     appeared normal until about 66 seconds when the sustainer engine shut down
     prematurely. The booster engine apparently continued normally to BECO. At
     about 255 seconds the payload SPDS engine ignited. Destruct was sent at 272
     seconds.
