A significant fire at a substation near Heathrow Airport on March 21 has led to the airport's closure, affecting over 1,300 flights and potentially impacting 200,000 travelers worldwide. The fire, which began late on March 20, prompted a major incident declaration and the evacuation of 150 people, while 67,000 homes experienced power outages. All operations at Heathrow will remain suspended until at least 11:59 p.m. GMT on March 21, with travelers advised to avoid the airport and check with airlines for updates.
