TTN There were many Flt Lts at BZN in my time with a big gap between the two stripes. I seem to remember that a posting to the OCU was not popular as you lost the little thin one in the middle. A certain Flt Lt PA (now AVM) had a Gp Capt in the jump seat when there was a flt deck visit. He was asked if he was going to take over for the landing. 'Good Lord', he said, 'no, I am a doctor'.
