1979-029A
Soyuz spacecraft 7K-T No. 49 was launched on 1979 Apr 10 and named Soyuz-33. Crew were civilian Energiya astronaut Nikolai Rukavishnikov and Bulgarian astronaut Maj. Georgiy Kakalov (although he was called Georgiy Ivanov in Russian sources.) On final approach to DOS 5 (Salyut-6), at a range of 3 km, an engine burn was aborted due to a malfunction. The rendezvous was abandoned and the crew prepared to return to Earth firing the backup engine. After the planned 3 min 8 sec burn, the engine failed to shut down on schedule, and had to be shut off manually 25s later. The result was a high-g ballistic reentry. The astronauts landed safely 320 km SE of Dzezhkazgan.
