Drifting clouds of volcanic ash from Iceland grounded hundreds of flights in northern Europe on Thursday, closing airspace in Britain, Germany, and Scandinavia.
Several British airports closed Thursday after a massive cloud of ash from an erupting volcano in Iceland drifted into Britain's airspace.
About 150 flights were canceled at Heathrow Airport，one of the world's busiest. Aberdeen, Edinburgh, Glasgow, Belfast and Newcastle airports were completely shut.
The Air Traffic Control Service (NATS) imposed restrictions after the Met Office warned that volcanic ash could damage engines. Passengers were being advised to contact their airlines prior to travel.
