In 1942, Pease is in charge of very important aircraft research during the Second World War. He needs to take a trip on a bomber to gain first-hand knowledge of the environment under which his special equipment is to be used. However, no one must know who he is. He goes as Lieutenant Farrow, a Royal Navy public relations officer. The bomber is hit over Germany and, ignoring a crewman's warning, Pease is sucked out through a hole in the side of the aeroplane, but parachutes safely to the ground.
