US grounds all departing flights due to ‘extraordinary circumstance, safety reasons’

The U.S. has halted all outbound flights due to an unspecified "extraordinary circumstance" that raises safety concerns, prompting a temporary suspension of departures while in-flight flights are allowed to land. This unprecedented move underscores the seriousness of the situation, likely involving a significant threat or system failure. The grounding reflects the government's commitment to passenger and crew safety, even if it causes widespread travel disruptions. This action could have broader implications for global aviation operations and highlights the delicate balance between safety and logistical flow.
