Description of Driving Event:

The SRB platform testing began by loading the platform with 32,000 lbs. of sand. The load was lifted off the ground with a four winch slow speed lift. After clearing the ground, a high speed lift was initiated. An observer reported that a second wrap was beginning on the drums. A slow up mode was initiated and after approximately 12 inches of travel the observer reported the drums were coming apart at the end ring welds. The platforms' "C" corner dropped then the "A" corner dropped. The platform then flipped over, broke the cables and fell to the ground.
