The Lubbock Lights
Partially explainedSummary
On the evening of 25 August 1951, three professors from Texas Technological College were sitting in a garden in Lubbock when a formation of twenty or thirty lights passed silently overhead in a shallow arc.
They were a geologist, a chemical engineer and a petroleum engineer. They were exactly the sort of witnesses the field always says it wants, and they saw it again on subsequent nights, and they never accepted the explanation they were given.
The explanation was birds.
The registry records that explanation, records that it remains the leading explanation, and records that the men who saw the lights went to their graves rejecting it, and that the head of the Air Force's own investigation wrote in 1956 that the lights were not birds, and did not say what they were.
What is documented
The witnesses. W. I. Robinson, professor of geology; A. G. Oberg, professor of chemical engineering; and W. L. Ducker, head of the petroleum engineering department, all at Texas Technological College.
The sighting. On the evening of 25 August 1951, sitting outdoors, they observed a group of lights, on the order of twenty to thirty, crossing the sky in a formation, silently, at speed.
They observed further formations on subsequent nights, and they attempted to make measurements.
The photographs. On 30 August, Carl Hart Jr., a freshman at the college, photographed formations of lights from his back garden. The photographs were published widely, including in Life.
The investigation. The case was examined by the United States Air Force under Project Blue Book, and by Edward Ruppelt, who ran it.
The first explanation. Birds. Specifically, plover, flying at night over the city, with the light of Lubbock's street lamps reflecting from their pale underparts.
The street lights matter. Lubbock had recently installed new mercury-vapour street lighting, which is bright and bluish-white and which had not been there before. A city that had just changed the colour and intensity of the light it throws upward is a city where things flying over it are going to look different.
Ruppelt's account, and his evasion. In his 1956 book, Ruppelt wrote that he had personally thought the lights were birds reflecting the mercury-vapour street lights, "but I was wrong. They weren't birds." He wrote that they had been positively identified as "a very commonplace and easily explainable natural phenomenon", that he had promised anonymity to the scientist who worked it out, and that he would therefore not say what it was.
He then did not say what it was.
The photographs are a separate problem. Hart's photographs show formations considerably more regular than what the professors described. The investigators were suspicious of them, could not replicate them, and the general assessment since has been that they are unreliable and possibly faked. They are not evidence for the professors' sighting, and the professors themselves did not think they matched what they had seen.
Leading explanations
Birds over new street lighting. Leading, not demonstrated.
Plover fly at night, in loose groups, and they have pale underparts. Under a city throwing new mercury-vapour light into the sky, a flock passing over will present as a set of pale luminous shapes in a rough formation, moving silently, at an unjudgeable distance and speed.
The silence fits. The formation fits. The unjudgeable altitude fits, because you cannot estimate the distance of an unfamiliar object against a black sky, and the professors could not, and they said so.
The witnesses rejected it, and their objection deserves to be stated. They maintained that the objects were too regular in their arrangement, moved too fast, and were too uniform to be birds. They were serious men and they were not persuaded.
The registry records the objection and notes that it is an argument from the appearance of the objects, made by observers who had no reference points and no way to establish range, which is exactly the circumstance in which such judgements are least reliable.
Ruppelt's silence. Unhelpful, and it has done more to keep this case alive than any of the evidence. A man in charge of an official investigation who announces that a case is solved and then declines to say how has, whatever his reasons, guaranteed that nobody will believe him.
What the popular version gets wrong
"Three professors saw it, so it cannot be misidentification." Three professors of geology, chemical engineering and petroleum engineering are three men with no particular expertise in identifying birds at night. Expertise is not transferable, and the assumption that it is has done a great deal of damage in this field.
"The photographs prove it." The photographs are of doubtful provenance, do not match the witnesses' own descriptions, and were regarded with suspicion by the investigators at the time. They are the weakest part of the case and they are the part most often reproduced.
"The Air Force said it was birds and everyone knew that was nonsense." The head of the Air Force investigation first thought it was birds. In his 1956 book he wrote that it was not birds but a natural phenomenon, and then refused to specify. That is a bad way to close a case, and a claim nobody can check is not the same as the bird explanation being wrong.
Current status
Partially explained. The leading account is birds illuminated by new city lighting. It fits the observations and has not been displaced, but it has not been demonstrated, and the Air Force's own investigator wrote in 1956 that the lights were not birds.
The registry keeps this record with an honest note attached, because this is not the archive's cleanest resolution.
The witnesses were credible and never accepted it. The photographs are probably worthless. And the official investigator declared the case solved while declining to say what the solution was, which is close to the worst thing a man in his position could have done.
It may well be birds. The registry files it as partially explained, and states plainly that the reason is partly the evidence and partly how the case was handled.
