A fire near Heathrow Airport has sparked travel chaos, with more than 1,300 flights affected.
More than 200,000 air passengers have had their flights to or from Heathrow cancelled because the airport is closed on Friday following a fire at a nearby electrical substation.
Thousands of homes have been left without power and more than 100 people were evacuated after a transformer within the North Hyde electrical substation caught fire in west London.
The airport, which is supplied by the substation, said it was among those impacted by the power outage.
Passengers are being warned to expect disruption for several days, and many planes and flight crews are in the wrong location.

A Heathrow spokesperson said: "Heathrow is experiencing a significant power outage across the airport due to a large fire at a nearby electrical substation. Whilst fire crews are responding to the incident, we do not have clarity on when power may be reliably restored.
"To maintain the safety of our passengers and colleagues, we have no choice but to close Heathrow until 23h59 on 21 March 2025. We expect significant disruption over the coming days and passengers should not travel to the airport under any circumstances until the airport reopens.
"We will provide an update when more information on the resumption of operations is available. We know this will be disappointing for passengers and we want to reassure that we are working as hard as possible to resolve the situation."
