Robert and Philip: A favorite source of mine indicates that KH-8 No. 52 is the same as OPS 2849. The KH-8's were the last of the film recon sats. They apparently carried a couple of film canisters, and were launched with at least two other payloads, usually designated SRV-1 and SRV-2. Also, the info shows the launch occured January 21, 1982 instead of January 1, 1982. Mike -- 41.087N 80.722W 330 meters Mike DiMuzio mdimuzio@cisnet.com
