On May 11th, 1950, the Trent family of McMinnville, Oregon claimed to have seen a UFO flying above their farm, and captured a couple of impressive (and now famous) photos of the strange object. According to The UFO Iconoclast(s)(1), a "lost" photo (pictured) purportedly taken by the Trents of the same UFO has recently surfaced and is posted at their website(2).
