My unpublished 1969 paper on this "classic" case (often referred to but never before available) caused the Condon report's chief investigator of that case to reconsider his conclusion.
"Serious" UFOlogists, led by physicist Bruce Maccabee, have decided to take a "firm stand" defending the authenticity of these photos. However, it should be noted that Maccabee's photographic analysis has also unambiguously "validated" the ludicrous Gulf Breeze UFO photos of Ed Walters, which are widely rejected as a hoax even by many UFO believers. If we assume that Maccabee's photographic analyses are reliable, we reach an obviously untenable conclusion: that Ed Walters has taken close-up photos of dozens of "genuine" ET craft. Maccabee was also recently taken in by a very simple photographic hoax, the Lawton Triangle UFO Hoax. Maccabee's credibility as a photo analyst having self-destructed, there is no reason to accept the McMinnville "UFO photos" as authentic, based on anything he says.
Recent painstaking work by researcher Joel Carpenter has stirred up a great deal of controversy. It strongly suggests that Trent's "UFO" may be a mirror from an old truck. However, Carpenter has removed all of his research from the Web, without explanation. Some of the text (only) remains here.
In another paper never previously available, Philip J. Klass, the dean of UFO skeptics, points out what Bruce Maccabee doesn't tell you about the Trent Photos.
UFOlogists claim that the illumination in the Trent photos (normal for the morning, but a physical impossibility for an evening shot, as the witnesses claim) was caused by very bright clouds reflecting the sun. Unfortunately for them, the U.S. Weather Bureau reported that there were no clouds at all in McMinnville that evening!
