Talking to some of the ATC guys at STN the other day.
Their reasoning behind rotary phobia was that the college uses helicopters as 'problems' if they want to upset a student's flow. After a bit this becomes understandably deep-rooted and the knee jerk reaction is rather negative.
We took most of an ATC watch for a trip the other week to keep the education going - you should have seen the expressions when I showed them the London Heliroutes map.
