Heathrow Airport will be closed all day on Friday, March 21, 2025, due to a major power outage caused by a fire at a nearby electrical substation in Hayes. The blaze, which broke out at 8pm on Thursday, led to the evacuation of roughly 150 people and affected power in around 16,000 West London households. Over 70 firefighters tackled the fire, and authorities have advised residents to keep windows and doors closed due to heavy smoke. Flights scheduled to land at Heathrow are being diverted, with no timeline confirmed for when power will be restored. While no injuries have been reported, officials warn of ongoing disruption and have urged travelers to avoid the area until the airport reopens. Continue here.
