Heathrow Airport in London was expected to be closed all of Friday, shutting down one of the world’s busiest air hubs and causing worldwide travel disruptions, after it lost power because of a fire nearby. An average of more than 220,000 passengers a day traveled through the airport last year, on flights offered by dozens of airlines to more than 230 destinations around the globe. Here is what we know about Heathrow’s closure. Heathrow said early Friday that it had been hit by a power outage, caused by a fire at an electrical substation supplying the airport. The London Fire Brigade said that it had been called to the fire, in western London, around 11:20 p.m. on Thursday, and had deployed dozens of firefighters.
