I've read this thread with some interest. I left the service some 27 years ago and I have to confess that I haven't got a clue WTF people are talking about. NCA - non commissioned aircrew?? AAITC - not a Scooby, likewise NCAITC (unless it's non- commissioned AAITC), PSO course - used to be Personal Staff Officer. AAITC DI FS - is that something to do with Flight Sergeant Drill Instructors?
Come on guys - give us oldies a chance to keep up!!
