Smudge, though if your heart isn't in it . . .
By the mid-60s the V-force was shedding copilot who didn't cut it for captaincy. One came back while on his punishment tour, he was a FAC with a driver and comma man and ear to ear grin. Others went to flt Sims.
One, and I always thought he was shafted, was eased out. He was an artist with polystyrene and hot wire and was joed with making superb, large sized, unit crests. He was off so long he failed a check ride on the sqn, did a short refresher IIRC, but never got back flying.
But there have also been some who worked the oracle. Just good enough to pass but not good enough for a plum and finished up on trucks as they wanted - high risk strategy though.
