New technology that scans airport runways for debris received U.S. approval as part of an effort to save the aviation industry billions of dollars a year in aircraft damage.

The system monitors a 7,000-foot runway at Boston Logan International with radars and high-definition video to ensure it is free of metal shards, rocks and other items that could damage a speeding plane, the U.S. Federal Aviation Administration announced today. If an object as small as a bolt lands on the runway, an alarm sounds in the control tower.
