FSX Scenery--Weston-on-the-Green UK for Microsoft Flight Simulator X and Horizon Gen-X VFR scenery Vol.2 only. Weston-on-the-Green in Oxfordshire is the home of the Royal Air Force Sport Parachute Association. Originally a military airfield with its origins in World War One, Weston has been the home of RAF parachuting for almost half a century. This scenery includes autogen trees for the local area, moving road traffic and an AI jump aircraft. Some additional freeware scenery object library downloads are required for the scenery to function fully. By Trevor Clark.
