https://www.youtube.com/watch?v=3Z_m7onLw74 Vladimir Komarov was sure that he was not going to survive his journey into orbit. The space vehicle was shoddily constructed and untested, and Komarov knew it wasn't ready yet. However, he chose to go anyway, as his best friend Yuri Gagarin was the backup pilot, and would have had to go in his place. This audio recording is of Komarov cursing the Soviet Union officials, shortly before his death.
