Ascent by balloon and gliding were the most common forms of flight when Alan Cobham was born in late Victorian London. By the time he died supersonic travel was an everyday event and man had walked on the moon.

Cobham was destined to become a highly influential figure in British aviation, participating in what could be termed one of the most pivotal periods of technology development in history.

Serving in the First World War, Cobham saw the potential for aviation as a mode of transport and transferred to the Royal Flying Corps, finishing the war as an instructor.

After the war he gained international recognition and a knighthood with a series of trail-blazing long-distance flights and the creation of his 'Flying Circus'.
