I left in the mid eighties and in those days it was the norm that after commissioning from the ranks, you never went back to where you came from. This gave you the chance to establish yourself as an officer and to avoid any piss taking from your previous colleagues. Is this still the case in the present day, much smaller RAF?
In 22 years non commissioned service I knew of several ex colleagues who were commissioned but I only ever bumped into 3, 2 aircrew and 1 engineer.
