When maggie on the election campaign, as DaveB points out we had armed coppers inside the hangar. Their boss decided to give them a security test one morning, being the slack alice hangar foreman at the time I was told about it. I wandered upstairs to talk to Derek Cook for some reason - lo and behold he was was looking out across the hangar.He calls me over and say " ere - who's that idiot?" Looking out there was a guy wearing white overalls(we all wore blue or red)with a flat cap on walking round the aircraft. Cookie then says " he must be a flipping copper, only a copper would dress like an idiot and think he looked normal" All this time the copper in mufti is wandering round whilst his men are sitting around picking their noses and scratching their a*ses totally ignoring him. For days afterwards Cookie was heard wandering the halls of Redhill chuckling to himself and muttering "why are coppers such Flipping idiots "
It was funny at the time - no offense to any law that may read this
We had many lectures from the mufti copper about security - yawn!
