EX. INDEX was the name of the Strike Force Dispersal exercise we used to do in the late '70s.
Unfortunately our INDEX aerodrome was RAF Finningley - in those days a Learning Command base full of baby navigators and trainee rear crew. We usually had the night off before the 'fly off'. Supposedly to get some rest, it invariably meant invading the OM bar and returning much later. The next day one often felt distinctly shabby!
The bus was due to return us from the bus on one occasion, but the driver was nowhere to be seen. So OC35 decided to drive us back to Charlie dispersal himself, much to the consternation of the MTO. Fortunately he did so safely!
