Someone should have spotted the alarming number of near misses in the skies over the nation's capital before the fatal midair collision that killed 67 people in January, and reviewing the data now could prevent future crashes, according to the head of the agency investigating the crash.
National Transportation Safety Board Chairwoman Jennifer Homendy emphasized to Congress Wednesday that the Federal Aviation Administration had data going back to 2011 showing that collision alarms were sounding inside cockpits at least once a month because of how close the planes were getting to helicopters. But the FAA didn't act, she said.
