Its a shame that the cash is not available for controllers to do PPL training as I believe they used to in the black and white days. It may give some a better idea of what a pilot is sometimes going through. When I did my IR I had a new ATC girl jump in the back and come along for the ride, she was horrified I wouldn't be able to look out of the window for the next two hours. It certainly showed her that there is more to it than moving the maggot around her radar screen.
