Dual test of TKS-VA manned capsule. Shutdown of the launch vehicle on the pad triggered the launch escape system, which pulled the top capsule away from the booster. The parachute system failed and the capsule crashed to the ground. The lower capsule remained in the rocket. The top capsule was to have been manned, but the inability to demonstrate two consecutive failure free launches of the Proton/TKS-VA combination made that impossible.

Dual test of TKS-VA manned capsule. One vehicle reentered and landed after two orbits, the other after one orbit. The top capsule was to have been manned, but the inability to demonstrate two consecutive failure free launches of the Proton/TKS-VA combination made that impossible. This launch successfully demonstrated the reusability of the TKS-VA capusle; the same pair had flown as Cosmos 997/998 on 30 March 1978. References: 1 , 2 , 5 , 6 , 67 , 274 , 439 .
