Safety investigators want more technology to prevent close calls on runways

An air traffic controller’s mistake led to a near collision between two jets on a foggy runway in Austin, Texas, last year, the National Transportation Safety Board said Thursday.

Investigators also called for critical safety technology and additional training, which they say might have prevented the incident, as federal regulators grapple with a growing number of close calls on runways across the country including one last week at Ronald Reagan Washington National Airport.
