Green’s fascination with aircraft first sparked his interest in speed.
“I’ve been very lucky to have [had] the world’s best day job, flying jet fighters for the Royal Air Force and doing something that I’m very proud of, which is defending the country as part of our armed forces,” he said.
Green served in Iraq, Afghanistan, Bosnia and the Falklands, flying RAF aircraft such as the Phantom, Tornado F3 and Harrier.
But he said travelling at hundreds of miles per hour in a car was very different from piloting a supersonic jet, due to the need to remain in contact with the ground and constraints relating to drag and acceleration and braking distances.
