A regional equipment failure at the Federal Aviation Administration’s Minneapolis Air Route Traffic Control Center (ARTCC) on August 6, 2026, led to a ground stop at Minneapolis-St. Paul International Airport (MSP) and disrupted flight operations across several Midwest airports.
Flight Operations Halted and Midwest Routes Disrupted
The equipment outage, which affected radar and air traffic control systems covering over 333,000 square miles, forced MSP to halt all departing flights starting around 2:30 p.m. local time. Arrivals were also limited, with some flights diverted or held in holding patterns. The disruption impacted flights arriving from or destined to several Midwestern states including Iowa, Michigan, Kansas, Missouri, North Dakota,
South Dakota and Wisconsin.
Omaha’s Eppley Airfield also reported flight delays and ground stops tied to the Minneapolis ARTCC outage, with airport officials advising travelers to confirm flight status before traveling to the airport. Some flights were diverted to other airports such as Pittsburgh during the outage period.
Outage Timeline and Delays after System Restoration
The ground stop at MSP was lifted around 4 p.m. local time after the FAA restored the affected systems. Despite lifting the ground stop, the MSP website reported 87 delayed departures as of 4:45 p.m. The FAA communicated that flights resumed normally once full restoration was completed, but residual delays extended into
the evening for impacted flights.
Official Statements on Causes and Recovery
An MSP spokesperson confirmed the ground stop was due to a “regional FAA air traffic center equipment outage.” An FAA spokesperson attributed the outage to telecommunication failures affecting the Minneapolis ARTCC’s air traffic control and radar systems. These services have since been “fully restored and flights returned to normal,” the FAA stated. The agency is investigating the cause as it continues a comprehensive overhaul of its air traffic control infrastructure.
Passenger Impact and Expert Commentary
Passengers experienced extended delays and diversions during the outage. Sierra Maatta, traveling on a flight from Dublin, said her plane was delayed almost an hour
and rerouted to Pittsburgh before returning to MSP. She described passengers coping by watching movies while waiting in the air.
Retired airline pilot Paul Jackson commented that the FAA’s air traffic control equipment is “very, very old and very, very out of date in many cases.” He noted the timing of the outage coincides with the FAA’s ongoing efforts to rebuild air traffic control systems “from soup to nuts” and stated, “what this points to is that it’s overdue. It’s well overdue.”
