Flights began taking off on Friday evening following hours of closure after a blaze at an electricity substation in Hayes cut power to the west London airport.
Following a fire at a Heathrow power substation that caused widespread flight cancellations and chaos, Ed Miliband has ordered an urgent investigation. Heathrow's CEO, Thomas Woldbye, stated he was "proud" of the airport's response, attributing the issue to an external source. Counter terrorism police are investigating the incident, and the airport expects to be back to full operation.
