I've read this very question over and over from you. At some point, I
said to myself why doesn't this guy just look up the answer?

BTW: According to the BFU Bulletin, in January 2006 it was 75% of the
reported accidents/incidents/whatever in Germany (counting only the
light SEPs).

Oh, and BTW(2): I had one incident when the tug lost its power just
after being airborne while I was in the glider behind. Believe me or
not, at that moment, I wasn't interested the least bit in statistics. I
survived and so did the glider I flew, but it was, well, a moment to
remember.
