Air traffic across the UK was disrupted on Wednesday afternoon after a major radar system failure impacted the London Control Area. Flights departing from Heathrow, Gatwick, Manchester, Stansted, East Midlands, and other major airports were temporarily suspended as engineers worked to resolve the issue, British media “BristolLive” reported.

According to the National Air Traffic Services (NATS), the technical failure occurred at the Swanwick air traffic control center. To ensure safety, NATS limited the number of aircraft allowed to fly in London’s airspace, which led to widespread delays, diversions, and cancellations.

By 5:00 p.m. local time, NATS confirmed that the affected systems had been restored and operations were resuming, although disruptions were expected to continue throughout the evening.

Passengers reported being stuck on planes or in airport lounges. Inbound flights were allowed to land, but many incoming planes had to circle or divert while departures were halted. The disruption also extended to Irish airports due to airspace overlap.

Aviation analysts and travelers on social media described the issue as one of the most significant disruptions to UK air traffic in recent years. Authorities have not yet detailed the cause of the radar failure, and investigations are ongoing.
