From the mid 80's to the early 90's the National SAFECONs were dominated by the University of North Dakota. Since the 92 or so, it's usually a toss up between UND or one of the ERAU's, with an occational smaller school once in a while.
I competed in the '93 & '94 National SAFECON's. My hat is off to all the competitors. With the advent of GPS and glass cockpits in GA aircraft, let's hope good old fashion pilot skills never become a lost art! I still put the skills/techniques I learned years ago from my time on the team, to use every day.
