Just before sunset on 11 May 1950, Evelyn Trent was walking back from feeding the rabbits on the family farm about 11 miles southwest of McMinnville, Oregon, when she looked up and saw a large, silvery, disc-shaped object gliding silently through the sky to the northeast. She called her husband Paul, who was inside the farmhouse. He came out, looked, ran back inside for the family camera, a Kodak Roamer loaded with film, and took two photographs from positions only a few feet apart before the object tilted and slid away to the west. The whole encounter lasted well under a minute. The photographs show a clearly disc-shaped object with a flat underside and what appears to be a raised centre section, or cupola, on its upper surface, hanging in the air above the farm. The Trents estimated it was roughly 30 feet in diameter and came within a quarter of a mile of their position.
The Trents were not seeking attention. They finished the roll of film over the following weeks, had it developed, and showed the prints only to neighbours and family. The prints ended up tacked on a wall in their bank, and only then did a local reporter coax the story out of them. The McMinnville Telephone-Register published the photographs on its front page on 8 June 1950, and Life magazine picked them up on 26 June, bringing them national attention. The two frames went into history, reprinted endlessly, and became some of the most famous UFO photographs ever taken. Paul and Evelyn Trent maintained their account for the rest of their lives, and they received no meaningful compensation despite the international publication of the images.
The government’s analyst
Seventeen years later, the photographs were subjected to the most detailed analysis any UFO photographs had ever received. In 1966, the U.S. Air Force commissioned the University of Colorado to conduct an independent scientific investigation of UFO reports, the project that became known as the Condon Committee, led by physicist Edward U. Condon. The committee’s final report, published in 1969, was broadly sceptical of UFOs as a phenomenon. But it contained a crucial anomaly, and the anomaly was the Trent photographs.
The analysis was performed by Dr. William K. Hartmann, an astronomer from the University of Arizona, who worked from the original negatives and set up a scaling system to determine the approximate distance of the object. Hartmann used objects in the near foreground whose distances were known, a house, a tree, a metal water tank, and a telephone pole, and compared them with the image of the UFO. He measured the relative brightness of various objects in the photographs and demonstrated that their distances could generally be calculated with an accuracy of about plus or minus 30 percent, and in the most extreme case he would be in error by a factor of four. His photometric measurements indicated that the UFO was intrinsically brighter than the metallic tank and the white painted surface of the house, consistent with the Trents’ description of a shiny object.
Hartmann’s conclusion was careful, and it has been quoted ever since. To the extent that the photometric analysis was reliable, he wrote, and the measurements appeared to be consistent, the photographs indicated an object with a bright, shiny surface at considerable distance and on the order of tens of meters in diameter. While it would be exaggerating to say that fabrication had been positively ruled out, it appeared significant that the simplest, most direct interpretation of the photographs confirmed precisely what the witnesses said they saw: an extraordinary flying object, silvery, metallic, disc-shaped, tens of meters in diameter, and evidently artificial, flying within sight of two witnesses. Project Blue Book, which had examined the photographs and interviewed the Trents, found no evidence of a hoax in either the witness interviews or the photographic analysis, and assigned the case the conclusion “unidentified.”
The sceptics’ case
Not everyone was satisfied. The sceptical case was advanced most forcefully by Philip J. Klass and Robert Sheaffer in the 1970s. Sheaffer argued, from the direction of shadows in the photographs, that they had been taken in the morning rather than the evening, which would contradict the Trents’ account of the time and suggest the photographs had been staged. The argument was technical, contested, and never conclusive, but it gave sceptics a foothold: if the time was wrong, the story might be wrong too.
The most serious challenge came much later. In 2013, the French organisation IPACO, the Image Processing and Analysis Company, published a comprehensive digital reconstruction of the McMinnville photographs using modern photogrammetric software and high-resolution scans of the original negatives, applying the same analytical methods used to authenticate forensic and satellite imagery. The IPACO team concluded that the object in the photographs was not consistent with a distant large craft, and that the images were consistent with a small model suspended from overhead wires. It was the opposite of Hartmann’s conclusion, reached with better tools, and it reopened the whole case.
Ufologists pushed back. Bruce Maccabee, the Navy optical physicist who had studied the photographs, argued they showed a genuine physical object, and pointed to the consistency of the Trents’ account over decades, the absence of any motive, and the fact that the photographs had been examined by multiple independent professional analysts whose conclusions were generally consistent with authenticity. The IPACO study, its critics said, depended on assumptions about the camera, the film, and the scene that could not be verified after sixty years.
Two photographs, two verdicts
The Trent photographs are the exception in the UFO record: a case with original negatives, preserved and studied, with no money sought, no publicity chased, and witnesses who never wavered. They are also the case that shows why the record stays unresolved. The same two frames, examined by a government astronomer in 1969 and by a French image-processing firm in 2013, produced opposite conclusions. Hartmann found a large, distant, shiny object. IPACO found a small model on a wire. Both used careful methods. Both cannot be right about what the object was, and there is no third test left to run: the negatives have been scanned, the shadows measured, the brightness compared, and the farm itself has changed beyond recognition.
The negatives themselves have a history worth noting. After the photographs were published, the original negatives passed through several hands, including the Condon Committee’s investigators, and they were eventually returned to the Trent family. Hartmann’s analysis depended on having those originals: the photometric measurements, the comparison of brightness between the UFO and the known objects in the scene, and the scaling calculations all required the unaltered negatives, not prints or copies. That is why later researchers have placed so much weight on the 2013 IPACO study, which also worked from high-resolution scans of the originals, and why the argument between the two analyses has never been resolved by appealing to better copies. Both sides had the best material available. They simply read it differently.
What the photographs prove, without doubt, is that Paul and Evelyn Trent saw something they believed was extraordinary, and that they photographed something in the sky above their farm on the evening of 11 May 1950. What they do not prove, and what no analysis has yet settled, is whether that something was tens of meters across and far away, or a few inches across and close to the lens. The Trents are gone now, and the photographs remain, two black-and-white frames of a silver disc over an Oregon farm, still among the best the field has, and still unexplained in the only sense that matters: nobody has shown, to everyone’s satisfaction, what was in them.
What is documented — and what is not
Documented: On the evening of 11 May 1950, Evelyn Trent saw a large, silvery, disc-shaped object over the family farm near McMinnville, Oregon, and her husband Paul photographed it twice with a Kodak Roamer camera from positions a few feet apart. The photographs were published in the McMinnville Telephone-Register on 8 June 1950 and in Life magazine on 26 June 1950. Project Blue Book examined the photographs, interviewed the Trents, found no evidence of a hoax, and concluded the case was unidentified. For the Condon Committee in 1969, astronomer William K. Hartmann analysed the original negatives and concluded that the simplest interpretation of the photometric evidence was a real, shiny, metallic disc, tens of meters across, at considerable distance, while noting that fabrication had not been positively ruled out. In 2013, the French group IPACO published a digital reconstruction concluding the object was consistent with a small model suspended from wires. The Trents maintained their account for the rest of their lives and received no meaningful payment for the photographs.
Unverified or unproven: That the object was a real craft of unknown origin; that it was a small model, since no model, wire, or staging evidence has ever been found; the exact size and distance of the object, which depends on which photometric analysis is accepted; that the photographs were taken in the morning rather than the evening, as the sceptical shadow argument claims.
