Seems like glider piloting is a problem (it can't be the iron fairy)
or is there another cause?

Measuring accidents on the basis of flight hours does not necessarily give you
the whole picture. If you had ever spent much time at a glider training
operation, you would quickly see part of the difference between power training
and glider training, and how the statistics can get skewed when you only look at
flight hours. Glider primary training flights tend to be so short that students
traditionally count "flights" rather than "hours". With gliders or airplanes,
accidents happen overwhelmingly on takeoff or landing. As it turns out, glider
students spend a greater percentage of their flight time in those two
(statistically more dangerous) phases of flight.
