The first Soyuz test flight was a catastrophic failure.   Due to negligence, the attitude control system malfunctioned and used all of its fuel before a rendezvous could be attempted or even the second Soyuz rocket could be launched.  When the Soviets attempted to return the first Soyuz to earth, the vehicle’s self-destruct system activated because it was unable to make a landing in the Soviet Union.  OKB-1 was disgraced.
