U.S. air traffic has largely returned to normal following an unprecedented nationwide grounding of flights. Saturday deadline. This marks only the third time in history that U.S. flights have been entirely suspended.

U.S. Secretary of Transportation Sean Duffy explained that switches and routers were overwhelmed with data, leading to system crashes. He clarified that while communication and radar systems did not completely fail, they provided inconsistent data, characterizing the issue as a problem with an "outdated network." Duffy did not specify the exact cause of the data overload.

Secretary of Homeland Security Mark Weilin assured the public that passengers were never in danger and that efforts to resolve the issue were ongoing. While a cyberattack has not been entirely ruled out, officials stated there is currently no evidence to support this theory. Initial investigations, as reported by CNN, suggest the glitch is not cyber-related.

An estimated one million passengers were expected to travel during the disruption period. Despite the lifting of the grounding order, airlines anticipate continued delays as flight schedules recover. Secretary Duffy warned that tens of thousands of passengers might have to spend the night at airports and urged Congress to approve $50 billion in emergency funding to upgrade air traffic control systems.

This incident follows two previous nationwide flight suspensions: one after the September 11, 2001 attacks and another in January 2023 due to a NOTAM system failure.
