AT A GLANCE

The McMinnville photographs of May 1950 taken by Oregon farmer Paul Trent are among the most extensively analyzed UAP photographs in history. The two Kodak photographs show a metallic disc-shaped object with a clear superstructure hovering over the Trent farm. Analysis by University of Colorado scientist William Hartmann concluded the photographs were genuine and represented an 'unknown object.' Photo forensics by the Condon Committee, ground shadow analysis, and photogrammetry all failed to identify conventional explanations.

DECLASSIFIED DETAILS

On the evening of May 11, 1950, Evelyn Trent was feeding rabbits at her family farm outside McMinnville, Oregon, when she noticed a metallic disc-shaped craft hovering over the property. She called to her husband Paul, who retrieved his Argus C3 camera and took two photographs before the object moved away and disappeared to the northwest. The photographs were developed, shared with neighbors, and eventually reached Life magazine, which published them in June 1950. The photographs show a clearly structured metallic disc with an underside flange and what appears to be a superstructure or tower on top. The objects appears large and is casting a shadow consistent with the ambient lighting. When the Condon Committee analyzed the photographs in the late 1960s, Dr. William Hartmann concluded that no definitive evidence of a hoax could be found and described the object as an 'unknown object in the air.' Subsequent analyses by Ground Saucer Watch, the University of Arizona, and other photogrammetry specialists repeatedly failed to identify the object as any manufactured model or known aircraft. The shadow and perspective geometry were consistent throughout both frames. The McMinnville photographs remain, after more than 75 years, one of the most credible and most-analyzed still photographs of an unidentified craft in UAP history.

KEY CHARACTERISTICS
  • Among the most extensively analyzed UAP photographs in history — 75+ years of scrutiny
  • Condon Committee's Hartmann concluded: 'unknown object' — no hoax evidence found
  • Photogrammetry and shadow analysis consistent across both frames
  • Metallic disc with superstructure visible — structural complexity inconsistent with simple model
  • Life magazine publication in 1950 made these the first globally distributed UAP photos
  • Multiple independent photo analysis teams over decades found no definitive explanation

O'Hare International Airport — Disc Over Gate C17

O'Hare International Airport, Chicago, Illinois, USA

A metallic disc-shaped object was observed hovering silently over Gate C17 at O'Hare International Airport by over a dozen United Airlines employees and flight crew. The FAA initially denied radar contact; a Freedom of Information Act release revealed internal FAA discussion of the event. The object punched a clear circular hole through the overcast cloud layer upon departure.
