NEXTGEN: efficiently moving aircraft to the next runway where they can't land. Former Air Traffic Controller Don Brown writes about the NextGen [air traffic control system], arguing that the limiting factor of air traffic capacity in the US is the fact that the vast majority of America's passenger traffic must travel on 100 runways as the result of our hub-and-spoke air transportation system.

My suspicion is that NextGen will enable a return to the old 1970's model for point-to-point air transportation.
