Lubbock Lights 1951: measured lights, unproven photos, an open file

From 25 August 1951, Texas Tech professors in Lubbock watched formations of faint lights cross the night sky, and on 30 August freshman Carl Hart Jr. photographed formations of 18 or 20 of them. Air Force investigators could neither prove his photographs fake nor identify what the professors saw.

Lights over a professor's back yard

In a briefing transcribed in March 1952, Captain Edward J. Ruppelt, who ran the Air Force's UFO investigation, told his audience about a case from Lubbock, Texas. Professors from Texas Tech were sitting in a back yard on 25 August 1951, discussing meteors, when a group of lights went over; about half an hour later, as they were wishing it would happen again, a second group passed ^[1].

In his 1956 book Ruppelt put the first sighting at 9:20 p.m. and named four observers: geologist W. I. Robinson, chemical engineer A. G. Oberg, petroleum engineer W. L. Ducker and physicist Dr. George. He described the lights as bluish-green, fifteen to thirty of them in a rough semicircle, moving north to south ^[10]. His two accounts differ on details: the briefing speaks of five professors, twelve formations over five or six nights and a second pass after half an hour, the book of four professors, twelve more observations over the following weeks and a second pass after about an hour ^[1][10].

the whole case is the most interesting one we've ever had.

Thirty degrees per second

According to the briefing, the professors at first assumed they were watching an Air Force missile and set up their own crude measurements: angles marked against the houses, a stopwatch, and a baseline at right angles to the path with two-way radios and homemade angle-measuring devices at each end, to get an altitude ^[1].

The altitude attempt failed. What they did obtain was the angular speed across the sky, 30 degrees per second ^[2]. In the book Ruppelt explained why that settled nothing: at an assumed 10,000 feet the lights would have been travelling about 3,600 miles per hour, but nobody knew whether they were higher or lower than that ^[10].

Now, that's the only measurement we've got on these things.

Carl Hart's photographs

The report of the Air Force Office of Special Investigations (OSI) records that a college freshman's pictures of the objects in formation appeared in the Morning Avalanche on 1 September 1951 ^[5]. On 20 September the OSI agent and Lt. John Farley of Reese Air Force Base interviewed him at home. He said that on the night of 30 August, about 11:30 p.m. CST, he was lying in bed watching the stars when a formation passed over the house. He took his 35 mm Kodak into the back yard, photographed a second formation at about 11:32 (two pictures) and a third at about 11:34 (three pictures). He could not find one of the negatives ^[5].

He estimated that each formation held 18 or 20 objects in a U or rough V, white, not twinkling, with a glow comparable to the moon ^[5]. The agent's photo data name the photographer as Hart and list Plus-X film exposed at f/3.5 for 1/10 of a second; Hart also said he saw two more formations on 1 September at about 11:20 p.m. but took no pictures ^[6]. The agent described him as an 18-year-old freshman at Texas Technological College ^[7]. The photo file kept with the case holds four prints under the date 30 August 1951 ^[9].

He seemed sincere in his efforts to relate all incidents to the best of his ability.

Real images, unproven origin

Ruppelt told the 1952 audience that he had talked to Hart twice and that OSI had questioned him about three times. On the last occasion agents offered to let him withdraw the photos quietly; he refused and signed a sworn statement. The professors, Ruppelt said, rejected the photographs, because what they had seen was too dim ever to be photographed ^[2].

The Air Force photo lab found that the negatives held actual images. The positions of the lights shifted slightly from frame to frame, and the density of the images was a little more than that of a bright planet ^[3]. In the book Ruppelt added that Hart could produce only four of his five negatives, that they were badly scratched, and that an attempt to repeat the shots with an identical camera produced only two badly blurred frames in four seconds. A physiologist and professional photographers told him this did not rule out Hart's account ^[10].

Ruppelt's own accounts date the photographs to 31 August, while the OSI interview and the photo file give 30 August ^[2][5][9]. They also disagree with each other: in 1952 he quoted Hart as waiting two days before developing the film, in 1956 as developing it the next morning ^[3][10].

The photos were never proven to be a hoax but neither were they proven to be genuine.

Matador and the wider series

The OSI investigation was opened on 17 September 1951 at the request of Reese Air Force Base, after a teletype from Air Materiel Command, and also covered a daytime report. A woman from Matador said that at 12:45 p.m. on 31 August a pear-shaped object flew about 200 feet in front of her car, five miles north of the town, then rose rapidly and moved away to the east in a circular pattern, with no exhaust or noise ^[4].

The Project Blue Book record card for Matador gives an estimated size of 40 feet long and 16 feet in diameter, notes that the duration was too short for a balloon, and lists the case as unidentified ^[8]. Ruppelt filed it under the Lubbock Lights together with a Sandia Corporation employee's report of a silent flying wing over Albuquerque on the evening of 25 August, and a radar target in Washington State that ATIC's electronics specialists put down to weather ^[10].

Birds, and an answer never shown

In 1952 Ruppelt said there had been a duck flight over Lubbock at the time, but attempts to photograph ducks at night by city light had failed, so if the photographs were not fakes they were not ducks; the professors rejected the duck idea outright ^[3]. His book describes a plover lead from an old man in Lamesa, a game warden's doubt that plovers fly in large flocks, and his own idea of birds reflecting mercury-vapour street lights, which could not explain reports from far away from those streets ^[10].

Popular accounts say the Air Force closed the case as birds reflecting city lights over Ruppelt's objection; his book says the reverse on both counts. Officially all the sightings except the radar target were unknowns, while Ruppelt personally accepted an unnamed scientist's identification of the professors' lights as a commonplace natural phenomenon, an explanation he never described ^[10].

No document in this file identifies what the professors or Hart saw. The OSI report of October 1951 ends with the case continuing in pending status, awaiting a lead from the OSI district in Lawton, Oklahoma ^[7].

They weren't birds, they weren't refracted light, but they weren't spaceships.
