Penshurst Airfield was an airfield in operation between 1916-36 and 1940-46. Initially a military airfield, after the First World War it was used as an alternate destination to Croydon Airport, with some civil flying taking place. The airfield closed following the crash of a Flying Flea at an air display in 1936, and was converted to a polo ground.

It re-opened during the Second World War
