Air travel nightmares returned to the UK on Monday after a “technical failure” caused a temporary nationwide halt to departures and arrivals at major airports during the peak summer holiday period.
The National Air Traffic Services (Nats) issued a widespread alert late afternoon following reports of aircraft stranded on runways, unable to receive departure clearance, and passengers trapped at major hubs including London’s Gatwick and Heathrow, Manchester, Liverpool, Edinburgh, and Birmingham. The scale of the disruption quickly became apparent, with leading airlines like British Airways announcing significant flight involvement, warning of delays and cancellations. BA emphasized the issue was “entirely outside our control” but apologized to customers, pledging efforts to restore normal operations “as quickly as possible”.
EasyJet issued similar advisories, urging passengers to check flight statuses. Although Nats announced the technical glitch was resolved within an hour, widespread repercussions were inevitable, expected to last for hours. Aviation expert Simon Calder described it as an “incredible collapse of the air traffic control system,” affecting “hundreds of thousands of people.” The chaos rapidly extended to incoming UK flights, causing delays at Irish airports like Dublin and Belfast, with ripple effects felt globally.
Passengers faced lengthy waits and frustration. Journalist Tom Joyner, aboard a plane at Gatwick, described the uncertainty and discomfort, noting the captain joked controllers were likely “rebooting computers.” Social media filled with images of stranded tourists and angry comments about recurring UK air travel woes. While the precise nature of the initial problem wasn’t disclosed, evidence pointed strongly towards a computer system failure.
Transport Minister Heidi Alexander confirmed she was briefed on the temporary shutdown, reiterating the “technical fault” explanation and stating she remained in contact with aviation authorities. However, the air traffic control system faced immediate scrutiny. Ryanair executive Neal McMahon demanded the resignation of Nats CEO Martin Rolfe, calling it “outrageous that passengers are once again suffering delays and disruption due to this continued poor management.”
This incident follows a history of similar disruptions. In March, a fire at an electrical substation caused an 18-hour blackout paralysing Heathrow, stranding hundreds of thousands. It was later revealed Heathrow’s CEO couldn’t be contacted during the emergency as he was asleep and couldn’t be woken. Another technical failure in the UK’s air traffic control computer system occurred in late August 2023, also during the holiday season, similarly restricting operations for hours.
