I don't have data on earlier accident and fatality rates but it would be great if someone smart who's inclined that way could analyze it (9B???).


Here's a link to some files summarizing Glider Fatal and Non-Fatal Accidents over a 20 year period between 1994 and 2013.

For the fatal accidents I went to the trouble to read the accident reports as categorize the accident by phase of flight (TO, LDG and FLT - in-flight) as well as probable cause (my categories) as follows - with percent of accidents:

Stall/Spin - 39%
Flight Into Terrain - 17%
Loss of Control - 14%
Midair - 8%
Incapacitation - 7%
Assembly/Config - 7%
Structural - 7%

I also extracted Stall/Spin Accidents as the the most likely way to kill yourself thermalling low and highlighted the three that were during a contest.. (Trigger warning - not fun to read this stuff when you know the people). I can't see that any were thermalling low to avoid an outlanding, except perhaps the Ventus 2 crash at Lea County airport at Hobbs in 1997 where it was reported the pilot made a low approach though no mention of circling and one could easily imagine the attraction of wanting to land on a runway.

If someone wants to sort through the 551 non-fatal accidents - 131 are on approach and 151 are during landing. Please have at it. I'm sure the accident report will mention if it was at a contest and at the home airport or a landout. Since they most likely interviewed the pilot there will probably be enough to read to get a sense of things - though accuracy of reporting may be questionable.
