Highly informative hour-long documentary about the Corona Project, which gave us America's first photo-reconnaissance (spy) satellites. Produced by the CIA in 1972, it premiered publicly at the "Piercing the Curtain" conference about Corona in May 1995 but has not been widely seen.
The streaming version has been posted as one file, but the two non-streaming versions (at medium and high resolutions) have been broken into two parts each.
