Can I make a wider point about something that nags at the back of my head occasionally. There appears, to me at least, to be amongst some flyers a bias towards whatever it is they fly, be it powered, gliders, microlights, paragliders or whatever. The truth is, if you hit someone while flying, it doesn't matter whether you are in the right or in the wrong. What matters is that you are most probably permanently dead. We all need to recognise the strengths and weaknesses of each others aircraft and the strengths and weaknesses of the pilots thereof and stop trying to score points.
Whilst I agree 100% with the sentiment, there seems to be a better than 50% survival rate amongst glider pilots following collisions - mainly because they usually wear parachutes. The fact that most incidents are glider on glider with lower energy than many powered aircraft probably contributes to the high percentage of successful bail outs.
