Volcanic ash cloud no fly zone signs

This is just one of a collection of no flying signs in the event of a volcanic ash cloud preventing air travel. It also contains some nice and clean jet airliner images. Jet engines and volcanic ash, so it seems, do not get along well. The ash melts to the hot turbine blades and very quickly changes their shape resulting in engine failure. With the massive disruption to flights continueing due to the icelandic volcano, if you, like me, are worried about your holiday, advice can be found on great sites like: globebloggers.com,  And if you'd like more infomation on why jets can't fly, take a look at Volcanic ash: who says flying's not safe?.
