Heathrow shutdown: how fire sparked a day of global travel chaos
A fire at a substation near Heathrow Airport caused major flight disruptions, affecting over 270,000 passengers.
The airport was shut down for 16 hours despite power being restored to the terminals within hours of the fire.
The cause of the fire remains unknown, but authorities have ruled out suspicious activity.
Heathrow Airport expects the final report to address key questions regarding the incident and improve energy grid resilience.
The final report, due in June, will cover infrastructure resilience, restoration processes, and the impact of energy-related issues on critical national infrastructure.
