"A shortage of airports runways and gates along outmoded air traffic control systems have made U.S. air travel the most congested in the world."

I belong to a group of men who fly alone. There is only one seat in the cockpit of a fighter airplane. There is no space alotted for another pilot to tune the radios in the weather or make the calls to air traffic control centers or to help with the emergency procedures or to call off the airspeed down final approach. There is no one else to break the solitude of a long cross-country flight. There is no one else to make decisions.
