Two of us - Navigators - going through UPT (1965) got in serious trouble with the "civilian" navigation instructor. On the E6B the instructor taught "wind up" in the wind triangle whereas Navs used "wind down." After class we taught our fellow students wind down. Come test time and the instructor walks around the class and sees everybody using wind down. He went ballistic. Two of us are given "counseling.

I apologize to the new generation who don't understand E6B and wind triangle let alone celestial navigation.
