Here we go again. This created quite a few headaches last year so hopefully this is only temporary and minor.
Volcanic ash blowing toward Europe caused a change of travel plans for President Barack Obama and spurred one airline to cancel most of its flights.
The plume, released when an Icelandic volcano began erupting on Saturday, is prompting Obama to leave Ireland early. A senior White House official told NBC News that Air Force One will depart for London tonight, while tomorrow's schedule "will proceed as planned."
Officials say they don't expect the problems caused by the Grimsvotn volcano to be as great as that caused by another Icelandic volcano last year that led to the grounding of almost all air traffic in Europe for several days amid fears that the ash could cause engines to stall. Authorities say systems and procedures have been improved, and the ash is currently not expected to move into continental Europe.
