Question/Instruction: Can you describe the McMinneville sightings and the photos taken by the farmer and his wife?

Given material: While many of these incidents were uneventful, a few cases involved nuclear missiles suddenly and simultaneously malfunctioning -- evidence, the military men say, that the aliens were curious about our weapons. And Leslie Kean, author of the book “UFOs: Generals, Pilots and Government Officials Go On the Record,” finds the argument compelling.
“The evidence is irrefutable for some kind of physical phenomenon,” Kean, a self-proclaimed UFO skeptic, told Fox News. “It’s well documented in the book through multiple witnesses, radar, ground traces that are left by things that land, and airline pilots.” Some of these incidents are as recent as 2006, such as the sightings at Chicago’s O’Hare Airport.
Hosted by Captain Robert Salas, a former U.S. Air Force nuclear launch officer along with researcher Robert Hastings -- the author of “UFOs and Nukes: Extraordinary Encounters at Nuclear Weapons Sites” -- the two plan to urge the government to publicly confirm the incidents on Monday, stating that they were ordered never to discuss the events.
Kean discussed several similar events with Clayton Morris, host of the Fox & Friends TV show.
“There was a disc that was hovering right over the United Airlines Terminal -- a round metallic-looking disc that lots of people saw. It’s hovering there for maybe five minutes minimum and suddenly shot straight up through the clouds above it,” Kean said.
Despite the amount of witnesses, none would go on record. “They’re worried about being ridiculed unfortunately,” explains Kean.
The Phoenix Lights was another incident this time witnessed by thousands of people in 1997, the most notable of which was then Arizona Governor Fife Symington.
Perhaps the most infamous sightings happened in McMinneville, Oregon over fifty years ago taken by a farmer and his wife pictured above.
“[They] are just out on the farm in the middle of nowhere when they saw this disc hovering overhead. They ran in, got their camera, and took two very very incredible photographs that have been well documented by laboratories for decades.
