I have recently been reminded that at the time we went through the selection process at RAF Hornchurch in the mid '50's, we were selected as Pilot/Navigators. Some of us were questioned at some length as to how we would feel if we did not make it as pilots and became navigators given that we would be signing on for twelve years. Consequently at Ternhill several did drop out from pilot training and were transferred to Navigation but the details now escape me.
