Historical Aspects of Organizing and Conducting Training of Cos-monauts for Space Flight on Soyuz-T Transport Vehicle. (Memoirs of Crew Trainer V.I. Vasilyev).

The 5th of June 2021 will mark 41 years since the launch of the first manned spacecraft of the Soyuz T series. The difficulty of training to fly on the Soyuz T spacecraft was that the entire training base, all descriptions and guides necessary to study the ship and prepare the crews in a regular way, lagged behind the pro-cess of vehicle designing. In the course of the first trainings and flights, the forms, methods and training programs were worked out. The problem of re-training cosmonauts who performed flights on the Soyuz spacecraft was particu-larly critical.
