Heathrow Airport in London, one of the world’s busiest air hubs, resumed full operations Saturday. But after a fire at an electrical substation halted operations for most of Friday, global travel remained disrupted.
Police were still investigating what had caused the fire at the substation in western London that cut power to tens of thousands of nearby homes as well as to Heathrow. The Metropolitan Police said there was no immediate indication of foul play.
A Heathrow representative said Saturday that the airport had hundreds of additional employees on duty and added flights to the day’s schedule to accommodate 10,000 extra passengers. An average of 229,000 people a day traveled through the airport last year.
