A very practical concept to start appreciating the tower environment, a diorama with models and basic scenerio's was still being used prior to going into the old tower sim when I trained in 89. Actually is quite helpful.
Lets face it the Russian Air Force still use it for briefing sorties with models, chalk and sticks to run the profiles, Putin was involved in one when he went bombing recently.
Don't forget the KISS principal still works.
