Description: Anatoly Zak recounts the July 1976 Soviet launch of the Salyut 5 mission, a secret military reconnaissance project camouflaged as civilian research. The mission, dubbed the "Keystone Cosmonauts," was plagued by accidents, including a truck blocking a fuel train and a failed automated docking system. Onboard, the crew faced extreme stress, power failures, and a mysterious illness that incapacitated one cosmonaut. These failures forced an emergency landing and a premature end to the expedition.
