Thanks for the maintenance, Jim!
You could even make it one shorter - 'hit a fence' is part of "crashed on landing" IMHO.
The fences only represent all kinds of deadly traps on unknown ground - like holes -
which could not be simulated. Planes often summersaulted on landing - even on their
own airfields. So the fences just stand for a "trap" we didn't regard - and it was
even a visible one, which we COULD have seen.

Then it might also be nice, if we listed a chart with the ways the aviators died.
But only when we have many more fallen pilots, of course.
