Not much gliding is taking place in this short clip: quite the opposite. A glider has been smashed and is being inspected by a group of gliding enthusiasts. The occasion is likely to be one of many Ulster Gliding and Aviation Club meetings over the summer of 1931.
This film is one of a series of clips from the Campbell Collection about gliding and aviation.
The film was probably shot by John Dermot Campbell and it is part of the Campbell Family Collection.
