A technical malfunction at the UK's National Air Traffic Services (NATS) on Tuesday afternoon caused severe disruption across Britain's aviation network, affecting at least 15 airports including major hubs Heathrow, Gatwick, Manchester, and Birmingham. Although the fault was resolved within roughly three hours of being identified near 2pm, the cascading impact of the outage persisted well into Wednesday and extended beyond UK airspace, affecting airports throughout Europe.

The incident left thousands of passengers stranded, with some enduring delays exceeding 16 hours. The disruption has highlighted a significant gap between passenger impact and compensation entitlements, as most affected travellers are unlikely to recover financial losses under existing aviation regulations. The outage underscores the critical vulnerability of centralised air traffic infrastructure and renewed questions around passenger protections during systemic failures.
