The RAF ceased operations at Lasham in 1948, but a military aircraft company, General Aircraft Ltd, continued to fly from the airfield. From 1951 the main activity at Lasham airfield became recreational gliding.The airfield is now owned by the largest British gliding club, also one of the world's largest, Lasham Gliding Society (LGS). It is also the location for 2Excel Engineering Ltd., a company that maintains large jet aircraft.Pilots of powered aircraft visiting the airfield require prior permission and a briefing on its hazards: in particular dense concentrations of thermalling gliders (up to 100 gliders can be in the vicinity at once), winch cables up to 3000ft above the ground, and occasional movements of large jet airliners. Over-flying aircraft are requested to not fly below 3618ft QNH. The airfield frequency is 131.025 MHz.Military historyThe airfield was constructed in 1942.
