Cobham Limited is a British aerospace manufacturing company based in Bournemouth, England. Cobham was originally founded by Sir Alan Cobham as Flight Refuelling Limited (FRL) in 1934. During 1939, British airline Imperial Airways performed several non-stop crossings of the Atlantic using equipment provided by FRL. During the late 1940s, the company's aerial refuelling equipment broke new ground, including a round-the-world flight by specially-equipped Boeing B-50 Superfortresses in 1948 and the demonstration of the now-widely used 'probe and drogue' method of air-to-air refuelling for the first time in 1949. A wide range of aircraft have since been equipped with Cobham's refuelling equipment.
