Frank Whittle’s fascination with aeroplanes started as a nine-year-old boy when he was nearly decapitated by one that was taking off from a local common in Coventry where he grew up. From that moment he set his sights on becoming a pilot, and joined the RAF in 1923. A few years later, aged just 21, he came up with an idea for powering aircraft so that they could fly much further and faster than the existing propeller planes. Despite a dearth of support from the Air Ministry, he doggedly pursued his vision of a turbojet engine and the RAF’s first fighter jet entered service towards the end of the Second World War, in 1944. His invention not only revolutionised air combat, but also international travel.

The inventor and entrepreneur James Dyson finds his story so inspiring that he has collected some of Whittle’s inventions, including an original working jet engine from 1943. He finds it amazing that Whittle got it right first time, which inventors almost never do. James Dyson is joined in the studio by Frank Whittle’s son, Ian Whittle, who is also a pilot.
