GD leaving ain't the problem, nobody is 4ever, it's the loooooooooooooooooooooooooooooong list of nasty's & bitter tasts left in employees mouths he's going to leave behind ! Maybe the 'oil pump' repair job wasn't that good, he'd ask the engineers for help, if he had any that cared !
Funny how the guys at 'ground' level know such things, without you lot the world stops turning !
