Volcanic Ash Shuts German Airports

European air travelers are facing another day of uncertainty because of Iceland's erupting Grimsvotn volcano. Germany is closing its northern airspace today because of volcanic ash, shutting down airports including those in Berlin and Hamburg, the BBC reports. Scottish, Irish, and Scandinavian airspace has also been affected, but officials say the ash cloud is slowly clearing and operations should soon return to normal. Transatlantic services have not yet been affected. (More Iceland volcano stories.)
