Albert M. Chop (died 15 January 2006) was the U.S. Air Force's civilian press officer for UFO matters in 1952–1953. He handled the media during the July 1952 Washington, D.C., sightings and later said the Air Force had planned to release an analysis of the 1952 Tremonton, Utah, UFO film before the CIA-sponsored Robertson Panel intervened.[1][2]
Career

A former newspaper reporter in Dayton, Ohio, Chop joined the press section of the Air Materiel Command at Wright-Patterson Air Force Base after the Second World War and became its chief. In 1952, at the request of Air Force intelligence chiefs, he was transferred to the Pentagon press section to handle UFO inquiries. He began as a skeptic but said his view changed after talking to senior officials who believed many sightings involved real craft of unknown origin. On the night of 26 July 1952 he was in the radar room at Washington National Airport as unknown targets were tracked over the capital and jets were scrambled. He later worked in public affairs at NASA's Manned Spacecraft Center in Houston.[1]
Chop and Keyhoe

Chop dealt regularly with Donald Keyhoe, who he said would often be waiting in his office with new questions. He cleared 51 sighting reports for publication in Keyhoe's 1953 book Flying Saucers from Outer Space, including the Tremonton case, and wrote a blurb calling Keyhoe a responsible, accurate reporter.[2][3]
The Tremonton film

On 2 July 1952 Navy photographer Delbert Newhouse filmed a group of bright objects near Tremonton, Utah. After about two months of frame-by-frame study, the Navy's photo laboratory at Anacostia concluded that the objects were not aircraft or birds and appeared to be intelligently controlled; an Air Force laboratory said they were not airplanes or balloons and probably not birds. In January 1953 the Robertson Panel suggested they might be seagulls. Blue Book chief Edward Ruppelt then wrote a press release, approved by the head of the Air Technical Intelligence Center, but the Pentagon rejected it.[4]
The CIA claim
Chop's account that the CIA blocked the release and ordered a debunking campaign comes chiefly from Keyhoe's books. The CIA's reading room includes a 1953 internal review of Keyhoe's book, showing that the agency followed what he wrote.[3][5]
Later years
Chop later joined NICAP and became a critic of official UFO policy. He was the central figure of the 1956 documentary-drama Unidentified Flying Objects: The True Story of Flying Saucers, in which he was played by Tom Towers.[1][6]
