Air traffic was severely impacted when a massive blaze erupted at the North Hyde substation in Hayes, West London, cutting off power to Heathrow Airport, one of the world's busiest air travel hubs. The fire, described by Britain's energy secretary as “catastrophic,” has halted all airport operations, causing significant disruptions for travelers globally.

Heathrow was expected to remain closed for the entirety of Friday, and officials warned that the flight cancellations could extend for several days. The airport, which typically handles around 1,300 flights daily, serves as a major transit point for millions of passengers heading to various international destinations.

Approximately 290,000 passengers are estimated to have been affected by the closure. Many flights that were already in the air upon the airport's announcement had to be diverted to surrounding cities and other European airports. Airlines, including British Airways and Virgin Atlantic, are in scramble mode, redirecting flights, cancelling schedules, and urging travelers not to come to the airport.

As recovery efforts continue, officials have confirmed that the fire is under control, but the cause remains under investigation. “There’s no suggestion of foul play,” said Ed Miliband. Hundreds of passengers now grapple with disrupted travel plans, with airlines working to rebook flights amidst the chaos. Meanwhile, significant losses expected for the aviation industry as airline shares waver in the wake of the incident.
