From what I know gliding is considered as one of the safest aviation sports... There is almost nothing can go wrong - no engine, no fuel, etc. And indeed, at least according to Israeli statistics there was only one fatal incident in recent years and it according to Civil Aviation Authority (CAA) report (Israeli NTSB that performs investigation on aviation sport incidents as well) it was most likely suicide.
When I look onto CAA reports there almost no reports on incidents and these that are reported are mostly minor. On the other hand if I look on other sports like Paragliding, Ultralight or Powered parachute, there are many incidents and there are fatal ones time to time. Ultralight for example looks very dangerous as you mostly fly at ~500 feet above ground so you have very minimal reaction time.
However, without normalization to flight hours or other measurements it is almost impossible to claim that gliding is one of the safest sports...
Can somebody point to some official data that provides normalized safety records according to different types of aviation so I can compare it for example with general aviation and with different aviation sports as well?
Thanks!
