I stumbled upon this link where someone has gone to the trouble (and I thank them for it!) of mapping the crash locations of the Belgian Air Force after 1945, complete with extra information.
I can't immediately find who created this map or how accurate it is, but it is certainly an excellent initiative with a great, useful overview. It would be nice if there was a way to contribute and supplement the information, but I don't immediately see that as an option.
