In a comment at Rich Reynolds' UFO Iconoclasts blog, my friend Lance Moody sums up the "Roswell slides" story perfectly, by way of an imagined conversation in 1947.
"Sir, we have a dead body from the flying saucer!"
"Very well, place the little green man in a container and be sure to put a placard on it so we don't forget where it came from! I will see if we can get a civilian Oil Geologist to come in with his wife to photograph the little guy."
"Very good, sir! "
Anyone who took any of this "slides" idiocy seriously (I'm looking at you, Roswell "Dream Team") is either completely detached from reality or a willing participant in a fraudulent exercise designed solely to cash in at the expense of the rubes (something of which "Dream Teamer" Don Schmitt in particular has a long and sordid history). Either way, it's one of the most laughable escapades in UFO "research" since the Alien Autopsy hoax.
