Soviets secretly selected first cosmonauts 60 years ago today

From the space history time capsule, Soviets secretly selected their first cosmonauts 60 years ago.

The Soviet Union fielded 154 candidates from the Soviet Air Force, narrowing down the pool to 29 candidates after medical tests at the Central Military Scientific Aviation Hospital in Moscow, and selecting the top 20 candidates as cosmonauts.
