At T+44.4 seconds the vehicle started a turn to the south and pitched down. The ISDS destruct system commanded the destruct packages at T+46.202 seconds. The ISDS failed to operate on two Castor 4 stage 1 motors but operated on the other four. At T+47.67 sec the ISDS destroyed a non-burning Castor 4B motor. The third stage Castor 4B and fourth stage Star 48 were not destroyed and impacted in the ocean. Cause of the failure was identified as the flight control system attempting to respond to noise being received on a data line, resulting in early depletion of hydraulic control steering fluid on stage 1 motor 6.
