Project 10073 Record Card and Air Intelligence Information Report — Sacramento, California, 9 November 1957

This document consists of a Project 10073 record card and an Air Intelligence Information Report detailing a UFO sighting that occurred in Sacramento, California, on November 9, 1957. The witness, a civilian, reported driving his car near the intersection of Madison Avenue and Auburn Boulevard at 0015 hours when his vehicle's engine stopped and the headlights failed. He observed an elongated, egg-shaped object with delta-shaped wings, estimated to be 150 to 200 feet long and 40 to 50 feet in diameter. The object, which exhibited a bright bluish hue and left a fluorescent bluish trail from its tail, hovered for two to three minutes at an altitude of approximately 1,000 feet before departing at a high rate of speed in a south-southeasterly direction. The report notes that the object's wings appeared to be welded to the fuselage. The witness further stated that the object departed when another vehicle approached from the opposite direction. The official military assessment, signed by Major James H. Kelly of the Base Provost Marshal's office at McClellan Air Force Base, dismisses the event as a product of mass suggestion linked to the concurrent 'Levelland, Texas excitement,' combined with the observation of a conventional aircraft.
