I have to wonder exactly what sort of 're-training ' can be necessary here... other than a simple statement to the effect of "do that again and you're in the mangle.
The skipper of a bloody great aeroplane full of people tells atc that he has a fuel problem and needs to land on the nearest runway... M word or not , it doesn't leave much room for any response other than to get the thing on the ground bloody fast... the why's, wherefores and maybe's can all be sorted out later at leisure but whatever terminology has been used you don't send the poor b*gger off on a cross country to suck up another 5 tons of fuel.
