There are some situations where you try to reduce type II errors (false negative) even if you increase type I errors (false positive).

The hypothesis is "the captain was to blame". If this is true but you reject it (type I error) you will probably loose another ship. If this is false but you reject it (type II error) you need to find another qualified captain (which, depending on the field might or might not be a problem).

My guess is that there are more pilots/captains trained that planes/ships.
