50% reduction of sustainer thrust for remainder of Stage II operation. Impact was
        2888 miles short of target.
. 63.   I (Yellow Jacket), 5 Dec 62, Response Mode 4T, Flight Phase 2: Missile was
        command destructed at 250 seconds. No other data available.

  64.   N-11, 6 Dec 62, Response Mode 4, Flight Phase 1: Stage I shut down 11.4 seconds
        early. As a result, no inertial velocity-dependent discretes were issued and Stage
        II shut down prematurely, apparently due to an oxidizer bootstrap-line failure.
  66.   N-15, 10 Jan 63, Response Mode 4, Flight Phase 2: Stage II flight was terminated
        by backup SECO approximately 34 seconds after ignition because low thrust
        caused velocity to fall below performance criteria. Cause of low thrust was
        reduced oxidizer flow through the gas-generator injector. Impact only 556 miles
        downrange.
  68.   N-16, 6 Feb 63, Response Mode 4, Flight Phase 2: Oxidizer depletion prior to
        normal SECO resulted in impact 71 miles short of target.
  69.   N-7 (Awful Tired), 16 Feb 63, Response Mode 4T, Flight Phase 1: Missile self-
        destructed at .56 seconds at an altitude of 18,000 feet due to loss of roll control.
        Failure was caused by improper umbilical release at launch and subsequent loss
        of vehicle electrical control.
  70.   N-18, 21 Mar 63, Response Mode 4T, Flight Phase 2.5: Although vernier ignition
        was normal, vernier #2 received no commands, and gimbaled erratically 2.8
        seconds later. R/V attitude was incorrect at separation so that impact was 4 to 5
        miles short of target.
  74.   N-21, 19 Apr 63, Response Mode 4, Flight Phase 2: Stage II engine shut down
        prematurely due to oxidizer bootstrap-line failure.
  76.   Titan I (Mares Tail), 1 May 63, Response Mode 2, Flight Phase 1: The missile was
        erratic from liftoff as one engine either failed at liftoff or shutdown immediately
        thereafter. The missile rose about 50 feet, then fell uprange from the launch pad
        about 7.5 seconds after liftoff.
  77.   N-14, 9 May 63, Response Mode 4, Flight Phase 2: Oxidizer depletion due to a leak
        resulted in premature Stage II shutdown and impact short of target.

  80.   N-20, 29 May 63, Response Mode 4, Flight Phase 1: A fuel leak in Stage I engine
        compartment at ignition caused a fire that spread through the engine
        compartment. Stage I destroyed itself at 52 seconds. Stage II was destroyed by
        RSO.
