The blaze led to a major power outage that brought Britain’s busiest airport to a standstill
A fire, potentially caused by an electrical engineer's error, shut down Heathrow Airport, affecting thousands of travelers and grounding around 1,300 daily flights. The fire was brought under control by Friday morning, and flights resumed on Saturday. British Airways expects to run 85% of scheduled flights on Saturday as the airport returns to normal operations. An investigation into the power outage has been ordered.
