Computer fault identified as UK flight chaos abates

(MENAFN- Saudi Press Agency)  A system failure affecting air traffic control workstations was to blame for disruption to thousands of passengers coming in and out of Britain's biggest airports, officials said, as services returned to normal on Saturday, Reuters reported.

A small number of flights remain delayed or cancelled at London's Heathrow Airport, which calls itself the world's busiest international airport, according to its website.

Air traffic officials said Friday's system failure occurred during a switchover of air controllers' workstations, which are put into operation or placed on standby as demand varies.
