A lot of talk here about ash damaging/clogging engines, but what
about the toxicity of the upper atmosphere? If there are large amounts
of sulphur etc then that's going to be drawn in to the packs and the
air con. So whilst the ash particulate size/dispersal may not be a hazard
in a couple of days (falls due to gravity) what about the noxious gasses?
Who wants a lung full of that?
