A corrupted computer file led to the breakdown of an air-safety system that prompted flights to be grounded across the US, according to people familiar with the preliminary findings.
The glitch that affected the Notice to Air Missions, or Notam, system on Wednesday also caused a failure in a related backup system, said the people, who asked not to be identified discussing the ongoing investigation. They cautioned that the information was not final.
