Air Traffic Controllers are highly skilled professionals, although at least 3 mid-air collisions [0][1][2] involving airliners have been a direct result of limitations in the radar technology. Newer technology like SSR gives the controllers better tools to use their skills. Practically every pilot has heard of the Tenerife disaster, and is commonly discussed in flight schools. A lot of safety changes in aviation can be tied back to previous mishaps. In Naval Aviation, the flight standards program is known as NATOPS [3] (Naval Air Training and Operating Procedures Standardization), and the phrase "The NATOPS has been written in blood" is largely because it dramatically reduced the mishap rate, and changes are often as a direct result of previous mishaps.
