For pilots, this means relying on programs like WSI Pilotbrief and SkyPath to plan out flight routes.

对于飞行员来说，这意味着依靠像 WSI PilotSimple 和 SkyPath 这样的程序来规划飞行路线。

Even the peacetime intercepts that the Mig31 carried out on the SR71 were only ever truly possible because the SR71’s flight route was well known to the Soviets.

即使是和平时期米格 31 对 SR71 进行的拦截也只是因为 SR71 的飞行路线为苏联人所熟知。
