A friend does a lot of filming with Go-Pro`s in his ASW-20 glider, a lot of cliff soaring etc, he got to the cliffs the one day and the wind was not where he thought it was coming from, ended up ditching in the sea, unfortunately the cameras went with the glider or we`d have some interesting footage to see, glider sank and was smashed up against the rocks, a right off.
Some footage of the sort of films he does, very good.!!!!
