February 1974. Andrew Hill who was only  10 years old at the time,  flew  a McBroom Arion at Wittenham Clumps.  The   glider was a 50% scaled down model made from a set of Geoff' Mcbrooms plans with no kingpost.  It had a 10ft   leading edge and a very small 'A' frame. Andrew was the son of Roy Hill, who went on to become president of the BHGA for a few years.
