A spokesman for the 11th Naval District said a cylinder containing highly pressurized gas used in rocket testing exploded during a test of a missile. Killed instantly was Hubert J. Stanfill, 30, a Navy ordnance man normally stationed at China Lake, Calif. Injured were James Crowder, 36, a guard of Garden Grove, Calif.; Jess Moss, 38, a Navy technician from China Lake. The test station at the island, located about 60 miles off the San Diego County coast, conducts experimental missile firings programmed by Navy in Pasadena, Calif. The Navy declined to give additional details of the explosion. The cylinder involved reportedly was of a JATO type used in the so-called jet-assisted-takeoff of airplanes.
