Heathrow Airport has been forced to close all day after a huge inferno left at least 1,351 flights cancelled.
The UK's largest airport was reduced to chaos in the early hours of Friday morning after a blaze at a nearby electrical substation caused a mass power outage overnight.
More than 16,300 homes have also been facing blackouts due to the fire raging from the electrical substation in Hayes.
Around 70 firefighters and 10 fire engines are battling the blaze on Nestle Avenue, London Fire Brigade has revealed.
