US Flights Grounded Nationwide

An unprecedented nationwide ground stop was enacted across the United States on Friday, impacting air travel significantly. The Federal Aviation Administration (FAA) issued this critical advisory around 4 p.m. EST, citing "extraordinary circumstances and for reasons of safety" as the cause for the widespread disruption.

Inbound international flights were subject to case-by-case management during this period. While the FAA did not immediately specify the exact cause, a source indicated that an upgrade to new software was a potential trigger for the extraordinary measure. This event marks a rare instance of such a comprehensive halt to air operations in the US.
