Sustainer engine shut down at 282 seconds.          Missile impacted 1300 miles
     downrange and 18 miles crossrange.
111. 114D (LV-3A)/Agena B (Ocean Way), 22 Dec 61, Response Mode NA, Flight
     Phase 2: Flight was considered successful although a failure in· the flight
     programmer prevented the SECO signal from cutting off the sustainer engine.
     Sustainer burned an additional 2.5 seconds to propellant depletion producing
     excess Atlas velocity.
114. 121 D (Ranger 3), 26 Jan 62, Response Mode NA, Flight Phase 2 and 5: Failure of
     pulse beacon in guidance system at 49 seconds caused sustainer to burn to LOX
     depletion, resulting in a 300 ft/sec overspeed. Due to malfunction of pulse
     beacon at 49 seconds, no guidance steering commands or discretes were given;
     Booster was cut off by backup signal from accelerometer, sustainer by fuel
     depletion. Due to excess speed, spacecraft passed 22,000 miles in front of moon,
     and primary mission objective was not met. All other Atlas and Agena systems
     performed as planned.
116. 1370 (Big John), 16 Feb 62, Response Mode NA, Flight Phase 1.5: Flight was
     considered successful, although RV did not separate properly.
118. 52D (Chain Smoke), 21 Feb 62, Response Mode 4, Flight Phase 1: A fire in the
     engine comparhnent resulted in shutdown of all engines at 60 seconds and vehicle
     explosion at 72 seconds.
119. 66E (Silver Spur), 28 Feb 62, Response Mode 4T, Flight Phase 1.5 and 2: Loss of
     helium-bottle pressure resulted in failure to jettison booster engines and
     premature vernier-engine cutoff at 131.5 seconds. Cutoff of verniers resulted in
     loss of roll control. Vehicle exploded at 295 seconds.
122. llF, 9 Apr 62, Response Mode 1, Flight Phase 1: An explosion in thrust section at
     0.9 seconds after about 6 feet of motion was followed by-a further explosion in the
     propellant tanks and total missile destruction at 1.2 seconds.
123. 110D (LV-3A)/ Agena B (Night Hunt), Midas, 9 Apr 62, Response Mode NA,
     Flight Phase 1: An autopilot malfunction prevented sufficient pitchover during
     booster and sustainer phase resulting in improper SECO conditions and an
     improper orbit.
128. 104D, 8 May 62, Response Mode 4, Flight Phase 1: Flight appeared normal until
     about 45 seconds when weather shield shifted~ Further shocks occurred at 50
     seconds with loss of weather shield. Booster-engine cutoff was initiated at 55
     seconds. Missile destroyed itself at 57 seconds due to breakup of Centaur upper
     stage. Recorded impact was 8500 feet downrange and 8200 feet crossrange.
