Two Italian brothers, incredibly, monitored the radio transmissions of the US and Soviet space race in the sixties. It’s a fascinating story of their ingenuity, the intrigue of the Cold War, and the possibility of a secret, behind-the-scenes Soviet space program.

They recorded a number of chilling transmissions which they claim are of lost cosmonauts from the black space program, hushed up and hidden by the USSR.

“It was a signal we recognised immediately as Morse code – SOS,” said Gian. But something about this signal was strange. It was moving slowly, as if the craft was not orbiting but was at a single point and slowly moving away from the Earth. The SOS faded into distant space.

Thanks, Guy, for the intriguing pointer.
