The eruption of the Grimsvotn volcano in Iceland has caused a huge ash cloud that is now affecting flights in Iceland and Scotland. Flightradar24, the live flight tracking Google Map, has now added an overlay to show the current position of the cloud.
The map shows the movements of flights in real-time. At the time of writing the map shows that most European flights seem to be unaffected by the cloud but there seem to be very few flights in and out of Scotland.
The BBC are reporting that flights to and from the airports of Londonderry, Glasgow, Edinburgh, Prestwick, Durham Tees Valley, Newcastle and Carlisle are likely to be affected by the ash cloud.
