Aleksey Leonov, the first human to conduct a spacewalk (1965), revealed that another pilot was involved with the death of Yuri Gagarin, the first human in space.
According to a declassified report, there is a human factor behind the tragic incident - an unauthorized SU-15 fighter jet was flying dangerously close to Gagarin’s aircraft.
“In this case, the pilot didn’t follow the book, descending to an altitude of 450 meters. I know this because I was there; I heard the sound and talked to witnesses. While afterburning the aircraft reduced its echelon at a distance of 10-15 meters in the clouds, passing close to Gagarin, turning his plane and thus sending it into a tailspin – a deep spiral, to be precise – at a speed of 750 kilometers per hour,” Leonov tells.
However, the ailing 80-year-old-pilot's name is still not being released.
At least we have an example of some state secrets being released ... without the need for a whistleblower to risk life and limb.
