Engineer
The engineer perhaps knew more about the B-24 than any other member of the crew, including the airplane commander. In emergencies, the airplane commander turned to the engineer. The duties of the flight engineer were to assist the pilot and copilot in monitoring the performance of the engines and to keep track of fuel burn. The engineer was usually also the top turret gunner, a position that allowed him to monitor the four engines.
