McMinnville UFO photographs
The McMinnville UFO photographs were taken on a farm near McMinnville, Oregon, in 1950. The photos were reprinted in Life magazine and in newspapers across the nation, and are often considered to be among the most famous ever taken of a UFO. The photos remain controversial, with many ufologists claiming they show a genuine, unidentified object in the sky, while many UFO skeptics claim that the photos are a hoax.
At 7:30 p.m. on May 11, 1950, Evelyn Trent was walking back to her farmhouse after feeding rabbits on her farm. Mrs. Trent and her husband Paul lived on a farm approximately nine miles from McMinnville (actually closer to Sheridan, Oregon). Before reaching the house she claimed to see a "slow-moving, metallic disk-shaped object heading in her direction from the northeast." She yelled for her husband, who was inside the house; upon leaving the house he claimed he also saw the object. After a short time he went back inside their home to obtain a camera; he managed to take two photos of the object before it sped away to the west. Paul Trent's father claimed he briefly viewed the object before it flew away.
Publicity and investigation
It took some time for Paul Trent to have the film developed, and he apparently sought no publicity immediately following the incident. When he mentioned the incident to his banker, Frank Wortmann, the banker was intrigued enough to display the photos from his bank window in McMinnville. Shortly afterwards Bill Powell, a local reporter, convinced Mr. Trent to loan him the negatives. Powell examined the negatives and found no evidence that they were tampered with or faked. On June 8, 1950, Powell's story of the incident—accompanied by the two photos—was published as a front-page story in the local McMinnville newspaper, the Telephone-Register. The headline read: "At Long Last—Authentic Photographs Of Flying Saucer[?]" The story and photos were subsequently picked up by the International News Service (INS) and sent to other newspapers around the nation, thus giving them wide publicity. Life magazine published cropped versions of the photos on June 26, 1950, along with a photo of Trent and his camera. The Trents had been promised that the negatives would be returned to them; however, they were not returned—Life magazine told the Trents that it had misplaced the negatives.
In 1967 the negatives were found in the files of the United Press International (UPI), a news service which had merged with INS years earlier. The negatives were then loaned to Dr. William K. Hartmann, an astronomer who was working as an investigator for the Condon Committee, a government-funded UFO research project based at the University of Colorado Boulder. The Trents were not immediately informed that their "lost" negatives had been found. Hartmann interviewed the Trents and was impressed by their sincerity; the Trents never received any money for their photos, and he could find no evidence that they had sought any fame or fortune from them. In Hartmann's analysis, he wrote to the Condon Committee that "This is one of the few UFO reports in which all factors investigated, geometric, psychological, and physical, appear to be consistent with the assertion that an extraordinary flying object, silvery, metallic, disk-shaped, tens of meters in diameter, and evidently artificial, flew within sight of two witnesses."
After Hartmann concluded his investigation he returned the negatives to UPI, which then informed the Trents about them. In 1970 the Trents asked Philip Bladine, the editor of the News-Register (the successor of the Telephone-Register), for the negatives; the Trents noted that they had never been paid for the negatives and thus wanted them back. Bladine asked UPI to return the negatives, which it did. However, for some reason Bladine never told the Trents that the negatives had been returned. In 1975 the negatives were found in the files of the News-Register by Dr. Bruce Maccabee, an optical physicist for the U.S. Navy and a ufologist. Maccabee did his own extensive analysis of the negatives and concluded that they were not hoaxed and showed a "real, physical object" in the sky above the Trent's farm. He then ensured that the negatives were finally returned to the Trents.
In the 1980s two UFO skeptics, Philip J. Klass and Robert Sheaffer, argued that the photos were faked, and that the entire event was a hoax. Their primary argument was that shadows on a garage in the left-hand side of the photos proved that the photos were taken in the morning rather than in the early evening, as the Trents had claimed. Klass and Sheaffer argued that since the Trents had apparently lied about the time the photos were taken, their entire story was thus suspect. Klass and Sheaffer also argued that the Trents had shown an interest in UFOs prior to their sighting, and their analysis of the photos indicated that the object photographed was small and likely a model hanging from power lines visible at the top of the photos. They also believed the object may have been the detached rear-view mirror of a vehicle. When Sheaffer sent his studies on the case to William Hartmann, Hartmann withdrew the positive assessment of the case he had sent to the Condon Committee. However, Maccabee offered a rebuttal to the Klass-Sheaffer theory by arguing that cloud conditions in the McMinnville area on the evening of the sighting could have caused the shadows, and that a close analysis of the UFO indicated that it was not suspended from the power lines and was in fact located some distance above the Trent's farm; thus, in his opinion, the Klass-Sheaffer explanation was flawed.
In April 2013, three researchers with IPACO posted two studies to their website entitled "Back to McMinnville pictures" and "Evidence of a suspension thread." They used proprietary computer software designed to analyze UFO photos by François Louange, who previously has done image analysis for NASA, the European Space Agency, and GEIPAN. They concluded the geometry of the photographs is most consistent with a small model with a hollow bottom hanging from a wire, though no thread was detected. Further investigation, however, detected the presence of a thread, and the study concluded: "the clear result of this study was that the McMinnville UFO was a model hanging from a thread."
In August 2013, UFO researcher Brad Sparks posted a rebuttal regarding the IPACO McMinnville UFO studies in which he stated that the studies contained multiple foundation measurement inconsistencies. An example of this was IPACO applying and working with a 5 inch diameter for the UFO [in the McMinnville photos] in some instances, and also applying and working with a 6 inch diameter for it in others. Sparks argued that certain measurements within the studies were manipulated whenever they proved unable to support the "UFO-model-hanging-by-a-string" hoax hypothesis.

Today, the McMinnville UFO photographs remain among the best-publicized in UFO history; and are among the most-discussed and debated. To many ufologists, the two photos rate as being among the most reliable and persuasive in arguing for the existence of UFOs as a "real," physical phenomenon. To many skeptics, however, the photos are likely hoaxes and/or fakes. Evelyn Trent died in 1997 and Paul Trent in 1998; they both insisted to their deaths that their sighting, and the photos, were genuine. The interest surrounding the Trent UFO photos led to an annual "UFO Festival" being established in McMinnville; it is now the largest such gathering in the Pacific Northwest, and is the second-largest UFO festival in the nation after the one held in Roswell, New Mexico.
