Ah Yes, 50+Ray. Converting from Co to Capt. I remember a certain doofus who was so nervous on his first left seat ride he hit the wrong start button. Number 4 instead of number 1 or whatever it used to be. Since the crew-chief was standing under the starter exhaust for the engine that was not supposed to be started things got a bit tense. We tested the limits of what an NCO can say to an Officer without getting court-martialed. The extremely humble and embarressed new-hire in the left seat had to make suitable aologies and amends at the end of the sortie. I never did that again.
