Robert Sheaffer provides (at Kevin Randle's blog) the Joel Carpenter analysis of the Trent/McMinnville photos
Robert Sheaffer checked in and provided, magnanimously, a link to a "lost" exegesis of the Trent photos by (the now deceased?) Joel Carpenter in 2004.
The analysis by Mr. Carpenter is a prime example of how a UFO sighting/event should be evaluated and here is the link that Mr. Sheaffer provided....and we thank him for making it available again:
(I normally wouldn't intrude upon Mr. Randle's effort but this Trent analysis is so good that I think it should be seen by as many ufological hobbyists as possible.)
