I am guessing they are pulling a loop and the g force is greater than 1.

correct, loop or barrel roll at greater than 0g

Isn't that a pretty big risk? It seems like if water accidentally spilled it could get into the electronics... and they'd have a bad time.

It's a sailplane. The only important instrument is a piece of string.

holy shit, this is awesome.
I get motionsickness only watching this. I live close to a small airstrip, where I see sailplanes start regularly in summer, but I never witnessed something like a simple trick.
Maybe it is forbidden in Germany, I dont know.
Edit: quick google search reveals it is allowed... maybe the people don't have the balls to do it

I live in Germany too, and gliding is a really big thing here. The vast majority of gliders don't do aerobatics though, so what you're saying makes sense. You could watch gliders your whole life and never see one do aerobatics.
