Pretty cool - would be interesting to split the fatal from non-fatal - and maybe other attributes.

If you go over to the "Map of Latitude" tab, you can set up filters on any of the fields... Click the blue "Filter" box, then "Injury Severity", and you can just select for fatal-vs.-nonfatal. Or you could filter on a range of Longitudes to see the East/West split. I'm a maps geek, so I always like my data to have a visual component .

Yep. And it can get interesting when you add additional layers of data.

If you're in the mood and someone comes forward with the data set, it would be interesting to add the "annual number of aerotows per location". There is bound to be some interesting anomalies (places with lots of tows and no accidents).

There was a discussion last year of the aerotow count survey on RAS, but I could not find it by searching. It would be interesting even if the data set were only available for a year or two if that caveat were prominently noted.

About a decade ago I searched through the NTSB database looking for all accidents that said "contest" "race" or "meet" to get a sense of what the problems with contest soaring are. The results are here

I've been too lazy to update it, but if anyone is playing with the data a similar search would be useful. As others have mentioned, not all accidents get reported.

A few years ago, I did a search to find the most dangerous common activities. Underground coal mining was the worst. Flying gliders is even worse.



The most amazing thing for me to try to understand is who we are. Well to do, educated, the movers and shakers.


Even more revealing would be to show the number of fatalities for CFIG, club presidents, etc. Many are high hour, experienced pilots.
THAT is what scares me! I don't get it.
