London’s Heathrow Airport, one of the busiest travel hubs in the world, has been forced to shut down following a major power outage caused by a large fire in the vicinity. The incident has brought operations to a complete standstill, severely affecting global air travel.

With Heathrow’s closure, more than 1,300 flights are grounded, potentially disrupting travel plans for tens of thousands of passengers. According to an airline analytics firm, as many as 145,000 travelers could be affected. The airport has issued warnings about significant disruptions that are likely to persist in the coming days.

Britain’s energy secretary confirmed that the fire also impacted Heathrow’s backup power system. However, he noted that it is too early to draw conclusions about the broader implications for Britain’s critical infrastructure.

The London Fire Brigade described the nearby blaze as a “prolonged incident,” with an increase in local disruptions expected. While the exact cause of the fire is still under investigation, the ongoing situation has left both residents and travelers facing uncertainty.

Experts in the aviation sector are predicting that the shutdown’s impact will ripple across the globe, potentially costing the airline industry hundreds of millions of pounds. The financial toll is expected to grow as the chaos could stretch over several days or even weeks.

An aviation analyst remarked that the aftermath of this shutdown will "undoubtedly cause chaos, not just over the weekend but well into next week," as airlines scramble to manage backlogged flights and stranded passengers.
