A power outage at Birmingham Airport has led to widespread disruption, with numerous flights delayed or diverted. The issue stems from a failure in the NATS radar system, which is crucial for coordinating air traffic. As a result, air traffic controllers are struggling to manage incoming and outgoing flights, causing significant delays of up to four hours. Passengers are advised to check the status of their flights before traveling to the airport. Emergency teams are working to resolve the problem and restore normal operations as swiftly as possible.
