LONDON: Britain’s Heathrow Airport was shut on Friday (Mar 21) after a huge fire at a nearby substation knocked out its power, stranding passengers around the world and angering airlines who questioned how such crucial infrastructure could fail.

Huge orange flames and plumes of black smoke shot into the sky around 2300 GMT on Thursday as a blaze engulfed the substation, cutting the power supply and backup system for Europe’s busiest and the world’s fifth-busiest airport.
