A glitch in the FAA’s computer system led to grounded flights across the country Wednesday, including at the Manhattan Regional Airport.

The Federal Aviation Administration suspended all flights after its Notice to Air Missions system, which sends hazard alerts to pilots, airports and airlines broke down Tuesday evening and sparked numerous delays and cancellations nationwide.

Flights at Manhattan Regional Airport, which has five daily flights to both Chicago and Dallas weren’t affected Tuesday, but on Wednesday, the airport noted the grounding delayed its morning flight to Dallas and cancelled its Chicago flight. The FAA lifted the order to ground flights by 8 a.m. Wednesday morning.

The White House said there was no evidence of a cyberattack leading to the outage, but an investigation was ordered by President Joe Biden.

U.S. Senator Jerry Moran, who co-chairs the Senate Travel and Tourism Caucus and serves as a member of the Senate Commerce Committee with jurisdiction over the FAA, promised to ensure the root cause of the failure is identified, noting the “nation’s traveling public deserves safety and continuity of service.”
