Missile Atlas 52D Test code named Chain Smoke ready for launch by the Strategic Air Command (SAC) from pad 576 B-3 at Vandenberg Air Force Base, California The missile takes off and begins its flight upward. At TC:01:49 some white smoke emanates from the missile and it is seen to be burning. A moment later it explodes in a huge fireball with pieces ejected trailing white smoke. The camera tracks the largest piece as it falls and crashes behind a ridge at the shoreline (likely into the water). Various vehicles are seen along fence line at secure area set back from the shoreline. (Note: The booster gas generator experienced a leak which resulted in high thrust section temperatures and eventual propulsion system failure. The sustainer and verniers shut down 49 seconds into launch, followed by the booster engines at 68 seconds. The missile destroyed itself at 72 seconds.)
