I think a bad airport has excess capacity, that it's not using well.

我认为糟糕的机场容量过剩，而且没有得到很好的利用。

So that when crises occur they can be well contained and that there’s excess capacity so there aren’t as many secondary effects from the crises occurring.

因此，当危机发生时， 它们可以得到很好的控制， 并且产能过剩， 因此危机的发生不会产生那么多的二次影响。
