Huge fire closes UK’s Heathrow Airport all day Friday after massive power outage — global flight schedules disrupted

"London’s Heathrow Airport, one of the busiest in the world, shut down operations all of Friday — disrupting hundreds of flights across the globe — after a massive fire at a nearby electrical substation cut off power to the airport.

Flyers are being advised to avoid the airport for the entire day as planes had already begun being diverted away from the British travel hub in the early morning hours.
“Due to a fire at an electrical substation supplying the airport, Heathrow is experiencing a significant power outage,” Heathrow said in a statement posted to X. “To maintain the safety of our passengers and colleagues, Heathrow will be closed until 23h59 on 21 March.” More than 1,300 flights are affected by the emergency closure, with potentially over 100,000 people having their travel plans altered."
