     S/ A-1 shut down at 213 sec due to failure of its turbopump assembly. The vehicle
     continued flight till 221 seconds when erratic attitude rates were noted. At 229
     seconds, the impact point stopped. At 257 seconds, the pressure dropped to zero
     in the stage-1 thrust-chamber assembly 2. At the same time, stages 1 and 2
     separated as stage 2 ignited. After this time, stage-2 attitude rates were erratic.
     Destruct was sent by the RSO at 273 seconds.
307. 34D (AFSC), 18 Apr 86, Response Mode 4, Flight Phase 0: At about 8.8 seconds
     after liftoff, the insulation and case of SRM No. 2 debonded resulting in case
     rupture immediately thereafter. The core vehicle was destroyed by fragments
     from the ruptured motor. Auto-destruct was activated on SRM-1 at 9.0 seconds.
311. 34D-3/Transtage, 2 Sep 88, Response Mode NA, Flight Phase 5: Transtage
     pressurization system failed due to damage to the upper portion of the transtage
     fuel tank and pressurization lines. A_ leak of 1,340 pounds occurred during park
     orbit, and a large helium-tank gas leak occurred during transtage first burn. Not
     enough helium was left in system to allow start of second bum. The payload was
     left in a geostationary transfer orbit.
315. Titan IV-1/IUS, 14 June 89, Response Mode NA, Flight Phase 1: Late in Stage-1
     burn, one of the engines failed and shut down. The other engine was able to
     gimbal sufficiently to maintain control until propellant depletion. Trajectory
     inaccuracies were compensated for during Stage-2 burn, and the mission was a
     success.
319. Commercial Titan, 14 Mar 90, Response Mode NA, Flight Phase 2.5 and 5: Boost
     phase was satisfactory. The payload separation system was designed for two
     satellites and had two discrete outputs from the missile guidance computer
     (MGC), but for this mission it carried only a single satellite. The wiring team
     miswired the harness, which connected the MGC payload-separation discretes to
     the payload separation device, so the satellite never received the separation signal.
     PKM and satellite did not separate from Stage II resulting in low-earth elliptical
     orbit. Ground controllers were able to separate satellite hours later but PKM
     remained attached to Stage II.
328. IV, 2 Aug 93, Response Mode 4, Flight Phase 0: A leak occurred in SRM#l at 99.9
     seconds that rapidly enveloped the vehicle in propellant gases. Approximately
     1.6 seconds later the vehicle blew up and disintegrated, apparently due to
     activation of the inadvertent-separation destruct system. . Destruct was
     transmitted at 104.5 seconds.
329. II/SLV (Landsat 6), 5 Oct 93, Response Mode 4, Flight Phase 2: Following a
     successful Titan-II second-stage burn and after payload separation, the apogee-
     kick motor failed to ignite and circularize the highly-elliptical orbit. The Landsat
     payload and Titan II followed a ballistic trajectory back into the atmosphere
     where bumup occurred.
