Heathrow will stay closed until midnight after a major fire hit a neighbouring electricity substation, and the record shows how fast one burning transformer can stop a global hub. The blaze broke out at around 11:23 PM on Thursday at the North Hyde substation in Hayes, West London. By Friday morning it had written off the day’s flying, with disruption likely to last days.
The shutdown caught aircraft mid-route. Planes normally resume at around 5am once the usual overnight lull ends, and roughly 120 inbound flights were already aloft when the day-long closure was announced; some turned back, the rest diverted across the UK and Europe. Friday’s closure was expected to touch more than 1,300 flights; Flightradar24 estimates 1,357. Amsterdam absorbed seven diversions, most of any field; Gatwick, Frankfurt and Shannon each took six.
Heathrow’s passenger count hit a record 83.9 million last year, one landing or taking off every 45 seconds; Civil Aviation Authority data puts 2024 traffic at 83,857,000. Analytics firm Cirium, speaking to the New York Times, believed up to 290,000 travellers could be hit on Friday, a headcount that would fill Wembley Stadium three times.
The London Fire Brigade committed ten fire engines and some 70 firefighters, with Assistant Commissioner Pat Goulbourne describing challenging conditions amid extensive flames and smoke. A 200-metre cordon went up; 29 people were brought out of nearby structures, more than 150 residents from surrounding properties. Scottish and Southern Electricity Networks fielded nearly 200 outage calls and said more than 16,300 homes across Hayes, Hounslow and nearby areas lost power, with no timeline for restoration. The cause is under investigation.
Driver Adeel Anwar called the fire “absolutely apocalyptic”, with “Billowing black smoke” over the airport and lights out along the roads around Hounslow and Southall. “The sky was darkening and it was just a scene that was chaotic. It looked like something out of a movie.” Passing the Hayes substation with his window open, he felt its heat.
Ed Miliband, the energy secretary, told Sky News “it was too early to know” what sparked the “catastrophic fire”, and counter-terror police are part of the multi-agency investigation. “We expect significant disruption over the coming days and passengers should not travel to the airport under any circumstances until the airport reopens,” Heathrow said, and all trains to the airport were suspended. Travel expert Simon Calder put passengers in “no man’s land”, though airlines are “absolutely responsible” for hotels, meals and re-routing on British or European carriers. British Airways was “working as quickly as possible”; Virgin Atlantic called the shutdown a “significant impact on our flying programme”; Ryanair mounted eight “rescue flights” across Friday and Saturday.
The salient fact for the file is the geometry: one substation, one fire, and a hub of 83.9 million yearly passengers went dark until midnight.
