Although I do not have any data I suspect it is so low as to be
negligible. So, if you infrequently fly over water and mountains, why
worry. Not to say that it can't happen, but you could also be hit by a
meteor while flying yet we don't worry about that.

You are responding to a guy that had an engine self destruct over somewhere
in nowhere on his way home from OSH last year. It happens.
