UK Air Traffic Failure Triggers Cascading Flight Cancellations

The breakdown revealed how deeply modern aviation depends on invisible infrastructure — and how swiftly its absence can strand thousands of lives mid-journey. From London's great hubs outward into the European network, the silence where guidance signals should have been became a reminder that the systems we trust most are also the ones we understand least until they stop.
