RAF Northolt Airport
RAF Northolt Airport is a Royal Air Force airbase in South Ruislip, 2 mi (3.2km) from Uxbridge in the London Borough of Hillingdon, West London. Approximately 6 mi (10km) north of London Heathrow airport, the airbase has a 5,500 ft (1.7 km) runway that can accommodate all jet sizes. It is open to private aviation, but requires a landing permit in advance as the airport is used primarily for military and royal family transportation. But be careful, the airport closes at night.
