March 21 (UPI) -- London's Heathrow Airport, one of the busiest in the world, reopened Friday night, 19 hours after flights were halted because of a "significant power outage," the airport said.

The airport was submerged in darkness due to a fire at an electrical substation that supplies the British transport hub. The substation fire, which is a mile and half from the airport, was reported to the authorities at 11:23 p.m. local time Thursday.
