I created something a while ago which might be of interest to this thread:

I got the data from the NTSB (searching on aircraft type glider). There are a few errors in the data, e.g. accidents in the middle of the Atlantic because the NTSB has the wrong latitude/longitude.

If there is enough interest, I could update the map with a different time range, and add tweaks like links to the full reports on the NTSB site. This was literally a 15 minute effort (I work for a Google competitor in the mapping industry, so I wanted to see how Google's APIs worked :-)).

Hope it helps the discussion!

Cheers,
