(TNS)
Mar. 21—Heathrow Airport in Britain's London was closed all day on Friday, March 21, after a major fire at a nearby electrical substation knocked out its power, disrupting hundreds of flights at Europe's busiest travel hub.
According to flight tracking service FlightRadar 24, at least 1,350 flights to and from Heathrow were affected, and the impact was likely to last several days as passengers try to reschedule their travel.
Around 120 flights were airborne when the closure was announced, forcing some to turn back, while others were rerouted to alternative airports, including Gatwick near London, Charles de Gaulle in Paris, and Shannon in Ireland, as per flight tracking data.
What happened?
Britain's Heathrow airport shut down early on Friday after a major fire at an electricity substation cut power to the sprawling hub.
London Fire Brigade was called to the "significant" blaze at Hayes in west London at 11:23pm ( 2323 GMT). It said 10 fire engines and dozens of firefighters were sent to the scene, while around 150 people had been evacuated from nearby properties.
London Fire Brigade assistant commissioner Pat Goulbourne said firefighters had worked "tirelessly in challenging conditions" and that around 8am the fire had been brought "under control".
The government would be "doing everything we can" to restore power to Heathrow, Energy Secretary Ed Miliband said.
The outage left 100,000 homes without power overnight, he said, but that power had been restored to all but around 4,000.
It was "speculative" to suggest at the moment that arson might have caused the fire, the chairwoman of a parliamentary transport committee, Ruth Cadbury, said.
"There are obviously questions about it," she told Times Radio.
