At 0600 CST on 12 February 1953, ten crew members of the 52nd Bombardment Squadron observed a delta-shaped bluish-white object approximately 15 feet in diameter during the preflight of a B-29 aircraft at Lake Charles AFB, Louisiana. The object showed white pulses behind it in pulse-jet fashion (each pulse smaller than the object) extending four times the object's length, resembling a flaming rag. Brightness exceeded that of Sirius with steady brilliance. Object approached from 130 degrees in straight and level flight at an estimated 5,000 feet altitude and 1,500 mph speed, then suddenly disappeared approximately 20 miles from observers. Duration 12 seconds. Weather CAVU. No traffic in area, no interception action feasible. Observers considered reliable.
