Planes start to land again after 1,351 flights cancelled or forced to land elsewhere
A fire at a London electricity substation caused widespread flight cancellations and delays at Heathrow Airport, impacting over 200,000 passengers. While the airport is "open and fully operational," significant disruption is expected for days. British Airways cancelled almost 80 flights on Saturday, adding to the 1,300 grounded on Friday. Airlines are working to reposition aircraft and crew, and some long-haul flights were diverted to various European airports. The fire is not being treated as suspicious.
