[Illegible], [ILLEGIBLE] - Incident Number: [Illegible]Date unknown

In early December 1948, the Air Force Office of Special Investigations looked into reports of green fireballs over New Mexico. On December 5, 1948, around 2105 (9:05 p.m.), an Air Force pilot saw an unidentified object like a green flare west of Las Vegas, New Mexico. He saw a similar object again at 2127 (9:27 p.m.) near the Sandia Mountains by Albuquerque. A commercial pilot reported a like object at 2135 (9:35 p.m.).

Agents interviewed police, forest officers, pilots, and airline staff across the area. Most had no reports to offer. On December 8, 1948, two agents themselves saw an intense green light near Las Vegas at about 13,500 feet. They could not identify it or judge its size.

A colonel reported seeing a bright white object, like a small sun and larger than a basketball, on three nights near Vaughn, New Mexico, in late 1948. Dr. Lincoln La Paz, a meteor expert at the University of New Mexico, said the lights could not be explained and did not seem to be meteors. The file does not give a final Air Force conclusion.
