In spring 1938 in the mountains in the north of Chile a fiery UFO, later named ‘Chilean Sphere’, fell down. The investigation of this episode, made by a film crew, has led to sensational discovery. It appeared that that before the Second World War (in the thirties) in the USSR a secret space program had been developed. The Soviet scientists and military authorities managed to launch the first spacecraft with a cosmonaut on board 23 years prior to Jury Gagarin’s flight.
