It's probably been done before but.........What branch were you in the RN and what are you doing now? This is nothing but sheer idle curiosity. I was an LREM when I left and since then was a 'Wireless mechanic' with the Edinburgh Police. A 'Laser Optical Calibration Specialist' (what that means was I tested the bloody things as they came off an assembly line) :?: with the old Ferranti in Edinburgh and an now a Comms Tech on an Oil Platform in the middle of the N Sea. With only 978 days until I retire and get the Hell out of it. Crap money, crap living conditions, crap job, but the time off is magnificent!
