Soviet space programme; now 30% bleaker

From an article on the development of the Soviet Energia rocket:

In the 1960's Glushko had favored use of toxic but storable chemical propellants in launch vehicles and had fought bitterly against Korolev over the issue. It is surprising that he now accepted use of Lox/Kerosene. But Korolev was dead, and the N1 a failure. Glushko's position had been vindicated, perhaps he now had to agree objectively that use of the expensive and toxic propellants in a launch vehicle of this size was not rational.

So remember, when your rival dies and then his project fails due to you being awkward and refusing to design appropriate engines, that's vindication.
