On July 30, 2025, a technical failure in the UK's air traffic control system, specifically a radar malfunction, caused the grounding of all departing flights from major UK airports including London Heathrow, Gatwick, Manchester, and Edinburgh. The disruption led to the temporary shutdown of London's airspace and widespread flight delays and cancellations, affecting over 150 flights and thousands of passengers. National Air Traffic Services confirmed the issue was resolved later that afternoon, allowing flights to gradually resume, but delays persisted into the following days. On July 31, cancellations continued with at least 16 flights from Heathrow and nearly two dozen flights across UK airports canceled as a result of the ongoing impact from the previous day's technical problems. Airlines such as EasyJet have demanded explanations following repeated failures. The incident marked a significant disruption to UK air travel infrastructure and operations.
