58.   SOD (Mercury), 29 July 60, Response Mode 4, Flight Phase 1: Flight appeared
      normal till 57.6 seconds when missile broke up apparently due to a rupture of the
      forward section of the LO2 tank.

61.   470 (Golden Journey), 12 Sep 60, Response Mode 4, Flight Phase 2: Flight was
      apparently normal until about 222 seconds, when missile acceleration began to
      decay. A LOX regulator failure caused. low sustainer performance and
      insufficient velocity to reach target. Impact was about 535 miles short.

64.   BOD (Able V/Pioneer), 25 Sep 60, Response Mode 4T, Flight Phase 2.5 and 3: Atlas
      performed normally except for failure of vernier engines to cut off. Flight was not
      successful since the Agena chamber pressure stabilized at 70% of normal shortly
      after ignition. Stage then apparently tumbled before cutting off 30 seconds early.
      Third-stage spun up and stabilized in a nose-down attitude.

65.   33D (High Arrow), 29 Sep 60, Response Mode 4, Flight Phase 1: The booster
      engines cut off prematurely and failed to separate from sustainer. The missile
      remained intact, but failed to achieve the desired range because of the added
      booster weight.

66.   3E, 11 Oct 60, Response Mode 5, Flight Phase 2: Sustainer hydraulic pressure
      began to decay at 41 seconds and dropped to zero at 62 seconds. Sustainer began
      tumbling at booster staging when control was essentially lost. Thrust continued
      for about 18 seconds moving the impact point some 270 miles farther downrange
      and 27 miles crossrange. The missile exploded at 155 seconds.
67.   570 (LV-3A)/ Agena A (Gibson Girl), 11 Oct 60, Response Mode NA, Flight Phase
      3 and 5: Atlas performance was satisfactory. An umbilical failed to release
      properly from the Agena at liftoff, resulting in loss of pneumatic supply to the
      Agena attitude control system. A satisfactory orbit was not achieved. Guidance
      beacon failed at 106 seconds resulting in autopilot flight.
68.   81D (Diamond Jubilee), 12 Oct 60, Response Mode 4, Flight Phase 1:
      Overpressurization of the LOX tank resulted in tank rupture and vehicle breakup
      at 71.6 seconds.

72.   4E, 29 Nov 60, Response Mode 5, Flight Phase 2: Sustainer hydraulic pressure lost
      at 41 seconds. Missile tumbled shortly after booster staging. Sustainer thrust
      terminated at about 150 seconds, some 22 seconds after BECO. During the
      sustainer solo phase, the impact point moved about 120 miles downrange and 44
      miles crossrange.
73.   91D, 15 Dec 60, Response Mode 4, Flight Phase 1: Vehicle performed normally till
      about 66.7 seconds, when a blast-band failure apparently resulted in rupture of
      the forward section of the LOX tank. The upper stages separated at this time, but
      the Atlas engines continued thrusting until 71 seconds. Control was lost between
