I had no qualifications when I did my two years NS in 1959.
Wound up as a J/T Ground Wireless [Mainly ILS Systems] at RAF Benson/Sylt
Plenty of interesting events and time erases the oft encountered guard duty/bullshine that came with being on camp where Queen's Flight were based.......
Watching the QF techs polishing that Dakota for weeks before it staged out to Nepal?? was fun...... it is now hanging up on wires at RAF Cosford........not as shiny as when it left Benson in 1961
