The way NATCO was set up on the ground side was that there were staff instructors, most of whom were not on the seniority list. A handful were from the military, a handful of college graduates with an aviation background from ERAU, Purdue, UND etc. and the others were retired NWA pilots. Each person would specialize in a particular system. Ground school was a class act all the way. Many were angling for an interview and a number made it onto the list. I think it was, teach for 3 years and you could be put up for an interview.
