Sir Henry Ralph Stanley Birkin, 3rd Baronet, known as Tim Birkin, was a British racing driver, one of the "Bentley Boys" of the 1920s.

Brooklands was a 2.767-mile (4.453 km) motor racing circuit and aerodrome built near Weybridge in Surrey, England, United Kingdom. It opened in 1907 and was the world's first purpose-built 'banked' motor racing circuit as well as one of Britain's first airfields, which also became Britain's largest aircraft manufacturing centre by 1918, producing military aircraft such as the Wellington and civil airliners like the Viscount and VC-10.
