Further north is the site of Hendon Aerodrome in an area of Hendon now known as Colindale. It was famous for the first airmail delivery; the first parachute descent from a powered aircraft; the first night flights; and, from RAF Hendon during World War II the RAF provided the first aerial defence of a city. It is believed that the first casualty in the Battle of Britain was an RAF Hurricane pilot from Hendon. It closed to flying in 1968 and is now the site of the RAF Museum, as well as the housing developments at Grahame Park and Beaufort Park.
