Our wonderings from Ockham Common, we crossed over to explore the disused Wisley Airfield. Originally a grass wartime airstrip, the runway was converted to tarmac in 1952 and used to test aircraft built at Weybridge by Vickers. Flying ceased in 1973 because the runway was too short for large aircraft and was too close to Heathrow. All the structures on the site were removed, except for the runway, and the land was sold back to its principal former owner in 1980 for agricultural use.
