Grandpa kind of became a football between Army Air Forces and Army Ground Force when he was drafted, different old sports injuries made him undesirable to each. His flat feet made him unsuitable for Infantry and a shoulder injury meant he couldn't fly, so when they saw that he was a GE-trained Master Machinist, Tool & Diemaker they stuck him wrenching on planes to get 'em ready for the WASPs to ferry and come up with last-minute "trick plays" correcting manufacturing defects to nudge whatever he could into "fit to fight".
