The way I heard it is this:
Soviets designed and built rockets to go to the moon. They tested them and the rockets did not perform. So Soviets kept working on it. Then US landed on the moon and the point became moot. Soviets stopped working on the rockets and put them away. Here is the important thing! They never figured out what is wrong with the rockets.
Fast forward 50 years later. Some organization needed rockets, but did not have money to buy new. So they bought used. They rebuilt/refurbished them and launched it. Problem. The original design did not work and never got fixed in the first place. So rebuilding/refurbishing the rocket did not really matter. Predictably when it was launched, it failed.
End file.
