Wellcome to the real world. After all that time you would think that a farewell from the RAF would be better. My departure was much the same, the only thanks I got was from the current Sengo of the day. the rest was just a walk round the station with a blue chit, exept for stores and I handed my uniform over.
Since the day I left my only contact has been my monthly pension, no contact to see if everything was ok or if I needed assistance or guidence. I am afraid that after that first step as a civvie you are on your own, the RAF has no interest in you at all.
