The opinion is expressed that it is time to air and investigate many areas of safety concern. This report deals with the positive control concept which is fundamental to the design and operation of the air traffic control (ATC) system. This concept, as it developed, has spawned a greater and greater emphasis on the radar environment. The radar environment and the Federal Aviation Administration's (FAA) commitment to it for the present and future, ATC system have created an increasingly complex, less growth-and demand-responsive system. Near midair collisions are far more prevalent in positive control airspace than in generally admitted by the FAA. In many respects the system has become less able to see and respond to abnormal situations. A NASA report demonstrates that there are more potentially catastrophic situations under positive control than is generally known and that some honest disinterested evaluation and recommendation process must be undertaken in the interest of aviation safety.
