The secret services of the USSR deceived American intelligence officers who were trying to get hold of the secret of Soviet pills, which supposedly helped astronauts to increase their endurance and stay in orbit for a long time. Nikolay Rybkin, the first head of the Star City, told about this funny fact.
According to Rybkin, Soviet cosmonauts carried out long flights in low-earth orbit, but the Americans did not succeed. It is not clear why, but the American intelligence officers decided that we had some kind of "miraculous" pills that make astronauts hardy and maintain their working capacity for a long time.
The Americans did everything to find out more about this drug, although this simply did not exist. And then our counterintelligence officers decided to slightly intrigue the Americans during joint flights. When the Soviet cosmonaut sat down to dinner, he defiantly took a pill from his pocket, drank it and gave it to his colleague, the flight engineer. The pill was ordinary - soda.
This event only further spurred the American intelligence services into their assumptions. When they tried to find out the origin of these pills, our counterintelligence officers specifically named another city, just to take them away from Moscow.
The Americans quickly began their own development of the "miracle pill", spent a lot of money, built a powerful laboratory, but they did not manage to find out the composition of the Soviet "magic pill". Yes, this is understandable, because it simply did not exist.
