May 28–29, 1952 — Albuquerque, NM
During a night refueling mission at 8:10 p.m., the crews of five USAF B-29 bombers see green spherical objects. The primary sighting takes place near Albuquerque, New Mexico, and involves three B-29s flying at 15,000 feet. Another sighting takes place around 11:30 p.m. about 10 miles southwest of Tulsa, Oklahoma. That crew is flying at 25,000 feet. Three hours later the final sighting takes place near Enid, Oklahoma, also with a B-29 at 25,000 feet. The aircrews making these reports do not think the objects are meteorites. [Eberhart]
