Major disruption affects flights at both Heathrow and Gatwick, leaving some passengers facing delays and cancellations. Multiple outlets report that the incident triggers an urgent review of what caused the disruption and how it unfolded at Britain’s airports.
The National Air Traffic Services (NATS) is carrying out an investigation to identify what went wrong. Coverage focuses on the need to understand operational failures and the events leading to widespread impact on departures and arrivals. One outlet points to the investigation as the next step toward establishing causes, while another frames the issue as a passenger-facing “meltdown” without adding specific technical details.
At this stage, details of the underlying cause are not fully established in the provided material. Reported emphasis is therefore on the scale of disruption and the formal inquiry process rather than confirmed findings or specific root causes.
