回答: Even without missile air crash happen all the time 由 HunHunSheng 于 2005-1-26, 12:21:58:
1) probability of accidental crash vs. that of missile attack
2) controllability (preventability) of accidental vs. missile
3) consequence of a crash caused by accident vs. missile
Let's say the first two are difficult to quantify, but the third one definitely will have an answer - a missile attack has much far-reaching consequences (economical, psychological,national security, etc) than a plain accident.
