Think the username says it all.
The best bit is the cost per hour. Since the glider is paid for, and insurance is a fixed cost, I like to work on the basis of:
cost of launch / length of flight = cost per hour
So a 4 hour flight on Sunday, off a 1500' aerotow, worked out at £4.65 per hour.
Just remember: There's no place like cloudbase
P.S. Although if I include the insurance, since I've not done a lot of gliding this year, Sundays flying worked out more like £46.50 per hour.
