Heathrow is back to being "fully operational" following a major fire at a nearby electricity substation, which led to the airport's shutdown and caused chaos in global air travel, leaving 250,000 passengers stranded.
By Saturday morning, the airport had regained power, and the terminals were lively, with flights taking off and landing. Heathrow, Europe's busiest airport, resumed operations more quickly than expected following the abrupt shutdown on Friday.
