This may be a silly question but I have got the impression from news programmes that the main problem with the volcanic ash in the skies has to do with jets. Both in the way that jet engines work and because they fly at a height which is where the volcanic ash predominates.
So would propeller-driven aircraft be able to operate pretty much as normal in this environment?
And would there be a market for some enterprising leasing company to perhaps "borrow" some large prop-driven aircraft like those Galaxies or whatever they're called from the military and fly a few hundred people home at a trot?
Just a thought, or have I got completely the wrong end of the stick?
