Re: of course it was U2s
Probably a lot less of the reports were for the never shot down SR-71
Now that I'm well past the age of caring.... a radar operator at a USAF radar station outside Charleston, SC, detected something flying high and fast in 1967. The Pentagon sent down a major to investigate the "UFO" (the "Purpose of Visit" entry in the orderly room sign-in book said "UFO investigation"). The major advised the operator he hadn't seen anything. I wonder if even that major was cleared to know about the SR-71, which probably is what was detected. The radar operator was a well-grounded, believably serious young man, so until I heard about the Blackbird I often wondered what it was he'd seen.
