FAA Outage: ground stop lifted but delays and cancellations continue | LiveNOW from FOX

The U.S. Federal Aviation Administration lifted its ground stop order on Jan. 11 after suffering a nationwide technical outage causing mass cancellations and delays. The travel chaos was caused by the failure of the FAA's Notice to Air Missions (NOTAM) system, which alerts pilots and other personnel about airborne issues and other delays at airports across the country. More than 1,000 flights were canceled in the U.S., and more than 6,700 more flights in the U.S. were delayed, as of 11:30 a.m. ET. FAA investigators are continuing to search for the cause of the outage. More LiveNOW from FOX streaming video
