As a gliding instructor I found that teaching CCF cadets, usually during Easter or Summer courses, was very different from the usual run of the mill weekend students. In my experience, CCF cadets were either very nice, good students, or bl**dy awful. You could almost guarantee that at least one CCF student per course was hopeless and would blame the instructors for their shortcomings.
On one course we had the son of the then Chief of the Air Staff and he was an extremely pleasant young man. During his course, as usual, we were suffering impossible weekday restrictions from nearby Boscombe Down and the other students were trying to get this lad to get his father to intervene on our behalf.
