"1950 - May 8 - This is one of the most famous UFO pictures ever taken. Photographed by Paul Trent, and first witnessed by his wife.
They were published in a local newspaper in McMinnville, Oregon, shortly thereafter. Soon, the Trent photos were published in Life magazine edition of June 26, 1950. The rest is history. These photos have been deemed authentic for over 50 years. One of the best early photographs of a UFO."
