DE: The Soviets seem to have difficulty implementing modern technology.
Would you comment on that?
Belenko: Well, let's talk about aircraft engine lifetime. When I flew the
MiG-25, its engines had a total lifetime of 250 hours.
DE: Is that mean-time-between-failure?
Belenko: No, the engine is finished; it is scrapped.
DE: You mean they pull it out and throw it away, not even overhauling it?
Belenko: That is correct. Overhaul is too expensive.
DE: That is absurdly low by free world standards.
Belenko: I know.
