The pilots of the Delta flight aborted their takeoff run following a frantic call from the air traffic controller in the tower. The two planes came within 1,400 feet of colliding, NTSB data released earlier this year found. It also follows two recent runway incursions at Ronald Reagan Washington National Airport, including one being investigated by the NTSB. Known as ASDE-X, the NTSB says the system helped stop the impending collision at JFK, but it is deployed at only 35 major airports in the United States. Such a recording would have provided key details about what happened, the NTSB said.
