例如，高速公路立交桥必须足够高，以便让运载军用导弹的拖车通过。

For instance, highway overpasses had to be high enough to allow trailers carrying military missiles to pass under them.

事实上，任何一枚卫星被摧毁都会随机性地产生数千个高速飞行的导弹；随之而来的任何一次撞击又会导致更高速运动的碎片。

Each destruction of a satellite creates, in effect, thousands of missiles zipping round randomly; each subsequent impact provides yet more high-speed debris.

但是到了六十年代末，洲际导弹已经成了核弹头的主流运载工具。大家都认识到超高速截击机(和超音速轰炸机)已经没有意义。

But by the '60s the ICBM had become routinized as the delivery vehicle for nuclear warheads and everyone realized that super-fast interceptors (and supersonic bombers) were kind of pointless.
