Soyuz TM-18-1 Abort

AKA: Ural (Urals). Launched: 1975-04-05. Returned: 1975-04-05. Number crew: 2 . Duration: 0.0149 days.

Carried Oleg Makarov, Vasili Lazarev for rendezvous with Salyut 4; but during second-third stage separation third stage failed to separate from second stage but still ignited. The crew demanded that the abort procedures be implemented but ground control could not see the launch vehicle gyrations in their telemetry. Soyuz finally was separated from by ground control command at 192 km, and following a 20.6+ G reentry, the capsule landed in the Altai mountains, tumbled down a mountainside, and snagged in some bushes just short of a precipice. The crew was worried that they may have landed in China and would face internment, but after an hour sitting in the cold next to the capsule, they were discovered by locals speaking Russian. Total flight duration was 1574 km and flight time 21 minutes 27 seconds. Lazarev suffered internal injuries from the high-G reentry and tumble down the mountain side and never flew again. Both cosmonauts were denied their 3000 ruble spaceflight bonus pay and had to appeal all the way to Brezhnev before being paid.
