Heathrow Airport orders probe into shutdown as travellers endure days of disruption

Aviation experts said the last time European airports experienced disruption on such a large scale was the 2010 Icelandic volcanic ash cloud that grounded some 100,000 flights.

London’s Heathrow Airport resumed full operations on Saturday and ordered a probe into how it dealt with a power outage that shut Europe’s busiest air hub for almost a day as airlines warned of further delays and cancellations.
