Abstract: When Aircraft using the airspace were few in number and airspeeds were relatively low, the "see and seen" method of collision avoidance served to keep what traffic there was adequately separated. Aircraft had virtually unhindered freedom to move in any of the four dimensions-up, down, left, or right. As the number of aircraft increased and the aircraft began to fly instruments, a need arose to safely separate them. This fact, coupled with the state of the art of navigational equipment available at the time, helped weld the airways structure passed down to this day. The subsonic jet transports have brought a realization that the air traffic system which the reciprocating transport aircraft lived with was not permitting the jet aircraft to operate most efficiently, i.e., cruise, climb, and deviate from the rigid air-route structure to circumvent or take advantage of of atmospheric conditions. The advent of the supersonic transport points to a return, full-cycle, to the days when aircraft could select the airspace they wanted to fly in. The question is one of how best this can be done.
