Summary

Five Texas Tech professors saw a group of lights pass over a Lubbock backyard on the evening of August 25, 1951, according to Captain Edward J. Ruppelt's March 1952 briefing. Ruppelt said they were discussing meteors when the lights appeared, that the lights returned about half an hour later, and that they counted 12 over five or six nights. The professors first assumed the objects were Air Force missiles and set up a baseline with two-way radios and homemade angle-measuring devices. They failed to get an altitude but measured an angular rate of 30 degrees per second, which Ruppelt called the only measurement the Air Force had.

Ruppelt said the Air Force heard of the lights about a month later. He interviewed the witnesses and first suspected a hoax. A college freshman photographed formations on August 31, using a Kodak 35 at 1/10 second on Plus-X film. Ruppelt spoke to him twice, and the Office of Special Investigations spoke to him about three times. He signed a sworn statement. The professors called the pictures faked. The Air Force photo lab found actual images and no proof of faking, and the negative density was slightly greater than that of a bright planet.

Ruppelt gave one mundane explanation: a duck flight was known to be in the area, and the lights could have been ducks reflecting city lights. Ruppelt said 75 to 80 feet altitude would be needed to fit the angular rate. Residents who tried to photograph ducks by city light failed, and the professors rejected the idea. Ruppelt said the Air Force was up against a blank wall. He also described a Sandia guard and his wife who saw a dark winged shape the same night, about two hours before the photographs.

A magazine article reproduced in an FBI file, credited to Dr. Menzel, gave a different explanation. It said temperature inversions could make distant city lights appear to float and fly in formation, and called this the Lubbock Light phenomenon. The article said he reproduced such effects in his laboratory. It gave the photographs' date as August 30, 1951, by Carl Hart, Jr., aged 18.
