I just found this picture, too late to include with the previous supercharged Bentley post. Quite a snapshot, Sir Henry Birkin was driving the Bentley at Brooklands in a record attempt when it caught fire inside the cockpit. He is standing up to get away from the flames, and is about to jump out of the car at about 60 mph. He was not seriously injured.
In another record attempts with the car he recorded a 137 mph lap. The size of the car is even more apparent in this shot.
