Avionics: The promise of air safety: Although air traffic has been increasing for years, installation of collision avoidance systems is only now being mandated

In 1974, according to the U.S. National Transportation Safety Board (NTSB), 467 deaths were attributable to commercial aviation accidents in the United States. This number more than doubled the fatality toll of 1973 and was the greatest for any year since 1960. Further, 1974 marked world aviation's worst disaster - the DC-10 Turkish Airlines crash near Paris, France, that claimed 346 lives.
