Human error may have caused BA travel chaos

The IT shutdown which left 75,000 bank holiday travellers with British Airways stranded may have been caused by human error, airline boss Willie Walsh has said.

Mr Walsh, chief executive of BA owner International Airlines Group (IAG), said the actions of an engineer who disconnected and then reconnected a power supply to the data centre in “an uncontrolled and uncommanded fashion” may be central to a newly ordered independent investigation.
