Another problem is that the airspace of all of northern Europe has been closed down because of the ash cloud. Apparently, the ash has a melting point that is just below the temperature inside a jet engine. So basically, the engines get clogged by lava. Not a good thing.
Also, the ash is apparently abrasive, so the cockpit windows slowly turn more and more opaque as the plane flies through the cloud. Also not a good thing.
Still, we shouldn't complain. The Icelanders are getting hit hard at the moment. First their economy collapses completely. Then a volcano erupts. Then that sets off another volcano with a glacier on top of it, causing massive floods. I dare say they are having a harder time of it at the moment than we are.
