 The death of a young fighter pilot, Valentin Bondarenko, in a fire during cosmonaut training in 1961 was also concealed by the USSR until 1986. At the other end of the scale, cosmonaut Grigory Grigoryevich Nelyubov was expelled from the program for brawling, and his image was subsequently airbrushed out of official photographs. There were also numerous reports of pre-Gagarin cosmonauts perishing in attempted manned spaceflights.
