Europe: The Ash Cloud's Aftermath

Iceland's Eyjafjallajokull volcano continued to spew ash April 21, although at lower altitudes than during the previous five days. Up to 75 percent of Europe's flights are expected to return to normal as result of the shift in Eyjafjallajokull's activity level. The ash cloud has affected air cargo transport and many of Europe's airlines. Because of its economic effects, the ash cloud could end up having political effects in Europe as well.
