Inquiry into glider death.
It is believed the man was taking part in a ten-day gliding contest in Nympsfield, Gloucester, when the accident happened.
He was removed from the plane by firefighters and taken to Gloucester Royal Hospital where he was pronounced dead on arrival.
A spokesman for Gloucestershire Police said the glider flipped over onto trees at the perimeter of the Bristol and Gloucester Gliding Club just after 2pm on Saturday.
Gloucestershire Police confirmed they would be liaising with the British Gliding Association and they will investigate. No one was available for comment from the Bristol and Gloucestershire Gliding Club.
