A while ago, National Geographic Channel, (re)aired a documentary called 'Near Miss'. I think this also should have been aired by something called 'The Learning Channel' or so (I don't know this TV channel, since I live in Belgium, Europe). It reported about the air traffic in the New-York Area, and about the life of the controllers over there. I can only tell you that I was amazed by the amount of traffic handled each day by JFK, Newark and LaGuardia.
