Well, I'm glad.
There certainly have been a lot of fatalities related to ditching though. Cold water shock; wires everywhere; heavy boots etc... My instructor used to compete in the birdman competitions and his view was that the uninitiated would be lucky to make it out.
I can't find the statistics at present, but I do remember reading in a BHPA magazine that drowning was the largest single mode of death in fatal hang-gliding accidents.
