Thanks BEags for reminding me of the wonders of Collyweston and those rivetting all lectures and films.
Another snippet from the 2-man concept - crew arrives at duly quarantined ac and shhhhh - show pass to dog and plod - enter area, start inspection/checks or whatever. After about two minutes up comes plod, asks us to 'look after things mate - dog's out of duty time!'. Now I know we (aircrew) get hassle about CDT, but..... It was a long time ago tho' (and what's this got to do with standards anyway?)
