I've always wanted to be an ATC. I didn't want to fly the planes, I wanted to be the ones to order them around.
Problem is my eyesight isn't the best. My dad, who has flown before, said that even with all the radars and equipment that they have at their disposal, ATCs still need to have good eyesight to search for the planes visually. (i.e. in case the equipment malfunctions)
I've seen that some colleges have degrees in Air Traffic Management and such. I think one school in New England has its own airport, so the students there get hands-on training in several aspects of air travel.
