Ruislip, Northwood and Pinner (UK Parliament constituency)

The 1948 Northwood mid-air collision took place on 4 July at 15:03 when a Douglas DC-6 of Scandinavian Airlines System (SAS) and an Avro York C.1 of the Royal Air Force (RAF) collided in mid-air over Northwood in London, UK (then in Middlesex). All thirty-nine people aboard both aircraft were killed. It was SAS's first fatal aviation accident and was at the time the deadliest civilian aviation accident in the UK. It is still the deadliest mid-air collision in British history. The DC-6, registration SE-BDA and named Agnar Viking, was on an international scheduled flight from Stockholm via Amsterdam to London's RAF Northolt. The Avro York of the 99 Squadron, with serial number MW248, was on a flight from RAF Luqa in Malta to RAF Northolt. The aircraft were two of four participating in a stacking at Northolt. At the time of the accident, the SAS aircraft was holding at 2,500 feet while the RAF aircraft was holding at 3,000 feet. However, due to an error in the setting of the atmospheric pressure compensation of the RAF aircraft, it may have been lower. At the time of the collision the DC-6 was ascending, as the pilots had minutes before decided to divert to Amsterdam and to leave the stacking.

Ruislip Lido ( RY-slip LY-doh) is a reservoir and artificial beach in Ruislip, within the London Borough of Hillingdon, England, situated between Ruislip Common, Ruislip Woods (a Site of Special Scientific Interest), and Poor's Field. Originally created as a feeder basin for the Grand Junction Canal in 1811, the reservoir was reopened in 1933 as a lido, with facilities for swimming and boating. During the Second World War, the lido was secretly used by the Royal Air Force to train aircrew based at RAF Northolt and RAF Uxbridge in water survival methods. A narrow gauge railway, the Ruislip Lido Railway was opened in 1945, and now runs about two thirds of the distance around the reservoir.Having fallen into a state of disrepair during the 1970s and 1980s, the lido has since undergone renewal works, and was the subject of an enhancement project unveiled by the London Borough of Hillingdon in January 2010. The project involved the return of boating and swimming in the reservoir, which had previously not been possible due to pollution and an artificially low water level.

The remaining woods were purchased from other owners and Ruislip Woods was formed.

Ruislip-Northwood was an urban district in west Middlesex, England, from 1904 to 1965. From its inception Ruislip-Northwood fell within the Metropolitan Police District and from 1933 it was part of the London Passenger Transport Area. The urban district council presided over a huge increase in population as the Metropolitan Railway gave rise to many new development opportunities. This created many challenges to improve public services and housing while preserving the area's heritage sites. In 1931 King's College, Cambridge sold their final plots of land to the council, having been owners of much of the land in the manor of Ruislip since the mid-15th century. The urban district was abolished in 1965 and its former area was incorporated into the newly established London Borough of Hillingdon, as part of Greater London.
