FAA has issued a nationwide ground stop halting all departing flights across the U.S. due to extraordinary circumstances and safety concerns

The disruption is caused by a telecommunications outage affecting multiple Air Route Traffic Control Centers, which has grounded takeoffs at major hubs including Chicago, New York, Los Angeles, and Boston.

Key details:

  • Cause: A communication issue impacting air traffic control frequencies and radar capabilities.
  • Status: All departing traffic is grounded until further notice; flights already in the air are permitted to land.
  • Impact: Thousands of flights are delayed or canceled, with no immediate timeline for resumption.
  • Security: Officials confirm there is no indication of a cyberattack or nefarious threat.
  • History: This is the first nationwide ground stop since January 2023 and the third since the September 11, 2001 attacks.
