To be fair, I've had Brunel lads (both on work experience and with shiny new LWTR Section Ls) alongside me in the hangar and they were generally all right except for being a bit slow and underconfident to begin with. It's quite a jump from the classroom to the hangar floor and they need time to find their feet. Give them simple jobs initially and more challenging tasks as they progress. A good minder will keep an eye on them, handing out advice, insults and grudging compliments in equal measures. YOU could be the guy they remember fondly in twenty years time...
I've also met a couple of plonkers as well, with an 'I know it all' attitude but they usually get sorted out.
