The McMinneville photo taken over the Trent Farm around 1950.
The website for Dr. Bruce Maccabee (PhD in optics) is http://brumac.8k.com, go to http://brumac.8k.com/trent1_2.html for the analysis of these series of photos.
What is interesting is that a few freepers have seen a similar craft over the years, last sighting was in the late 80's as I recall from earlier postings about such objects.
I think Maccabee’s analysis is quite sound.
Alas, I think you and I both know . . .
A percentage of folks . . . especially the louder ones hereon . . . will not be convinced until
. . . A UFO LANDS IN THEIR LAP
and gives them a video taped anal probe simulcast on CNN.
By then, their chagrin might be terminal.
