Did a Locking Craft app 68-70 as a Radar fitter. Most of my energy was devoted to surviving the experience rather than learning my trade. I learnt more in the first 6 months at my first unit (Bawdsey) than in my 2 years training. Not knocking it, just remembering how utterly unprepared I was as a J/T (God I was Crap) and had to be led by the nose by a 35 year old SAC. Bless him!!
