BBC News - Ash cloud 'could cause disruption in UK for 20 years'
An aviation expert has warned that the ongoing problem with an ash cloud, drifting from a volcano in Iceland, could cause disruption 'for more than 20 years' - affecting the UK and the rest of the world.
Speaking to the BBC, David Learmount said that there is no technological way around the situation, with no possibility of engines being designed that can withstand damage caused by ash.
He warned that any aircraft attempting to fly through ash would have its engines permanently damaged, and would be destined for the scrapheap.
