I don't think Iceland should be allowed to keep their volcanoes, they clearly don't know how to look after them !
Iceland -we said we want your CASH - not ASH !
Seriously chaps- could engine manufacturers not provide some sort of "filter" for this ash ? .(beyond what modern jet-engines already use )....cross-desert vehicles have them fitted...I know a jet-engine is far, far more complex-.. Don't flame me ,I am not an engineer.
