My son and I visited the Air and Space Museum of the Smithsonian two years ago and they had an exhibit on Corona (an early satellite reconaissance project). Unbelievable. Actual satellite FILM from the bird. Blew me away.
never heard of this... did the film come back to earth in a pod some how? How did it get back?
Try and visit the NSA museum at Ft. Meade. It's kinda small, but it has a lot of information on our history of spying. I really enjoyed the little bit they had on the Pueblo incident.
AND it has a gift shop...
(Right after 9/11, it was closed due to its proximity to Ft. Meade. I think it has since been reopened.)
