Heathrow finds itself under intense scrutiny after a fire knocked out power to force a complete shutdown of one of the world’s busiest airports on Friday (Mar 21).
The incident threw global travel into turmoil, with experts shocked by the scale of the outage.
Investigations into the cause of the fire, which occurred at a nearby substation, are ongoing, and the UK police have ruled out foul play.
