During the attack on the target, the Pathfinder plane directing the raid is shot down, causing the remaining bombers to begin bombing inaccurately. Hearing and seeing this, Mason takes the Pathfinder's place on the radio, broadcasting corrections and accurate instructions, and the bombing becomes accurate again. Listening-in to the Pathfinder's broadcast back in Britain, Mason's commanding officer, Group Captain Logan (Ian Hunter) hears Mason's voice and realises that he's disobeyed orders and flown on the operation. However, Mason's intervention turns the raid from a probable failure to a success, so on Mason's return Logan greets him at his aircraft.
