The radio operator's position was in the upper fuselage aft of the cockpit and the top turret. Cpl. Springer sat for hours on end listening to the static crackling in his ears and giving position reports every 30 minutes, assisting the navigator in taking fixes and informing headquarters of targets attacked and results. When needed, the radio operator manned the second waist gun.     Cpl. Springer kept a precise log of his tour. His daughter was kind enough to provide me with a copy and it was a great help in placing dates with events.
