A fire at an electrical substation near Heathrow Airport caused a significant power outage, leading to the cancellation of hundreds of flights and affecting travel plans for hundreds of thousands globally. The airport began reopening in the evening, starting a lengthy process to restore normal operations. The fire, which is still under investigation, disrupted both long-haul and short-haul flights, with some planes diverted to other European airports. About 4,000 tons of cargo were also stranded. The disruptions are expected to last several days as airlines work to reposition aircraft and accommodate affected passengers. U.K. Energy Secretary Ed Miliband emphasized the need for improved infrastructure resilience following this unprecedented event. — news from The Associated Press
