Heathrow Airport is back in business after a fire at a London electricity substation
A fire at a west London substation caused a 15-hour shutdown of Heathrow Airport, disrupting travel for up to 300,000 passengers and cancelling over 1,300 flights. An urgent probe has been ordered by the energy secretary and Heathrow itself, with criticism arising that the incident was a "national embarrassment" and a "planning failure." The fire, involving transformer oil, knocked out the substation and its backup, leaving Heathrow with limited power.
