Multiple major US airlines, including Delta, United, and American Airlines, have grounded all flights due to a communication issue reported by the Federal Aviation Administration. The ground stop affects all flights from these airlines, with no clear timeline for when operations will resume. The issue is linked to a widespread problem causing computers running various CrowdStrike sensor versions to experience a “blue screen of death” error. CrowdStrike is investigating the cause, and Microsoft has reported service disruptions for some customers in the central United States. Further updates are expected from the FAA.
