 The crew initiated a steep descent and manually programmed the auxiliary engine to run for 187 seconds, slowing down the spacecraft enough to place it in a landing corridor.Rukavishnikov, who had excellent command and experience of the Soyuz flight systems, switched off all automatic landing programmes.With the descent in progress, both Ivanov and Rukavishnikov felt that the damaged auxiliary engine had not provided enough impulse and decided to run it for another 25 seconds to further reduce the landing velocity.
