The new guidance allows a phased reintroduction from 2200 tonight of much of the airspace which is currently closed due to the volcanic ash plume over the UK. There will continue to be some ‘no fly zones’ where concentrations of ash are at levels unsafe for flights to take place, but very much smaller than the present restrictions. Furthermore, the Met Office advise that the ‘no fly zones’ do not currently cover the UK.

But that is the real question we can all see the billowing solid black clouds at the point of the eruption and no one would want to touch that.
But 2 Km, 20 km, 200km, 2000 km ??? downwind? at what point downwind does dispersion make a serious threat to life and limb become minimal to no threat?

I'll assume that you've not read anything on here at all as to the effect of silica in the engines of the Finnish F18s, NASA's DC8 in an earlier eruption, the air samples taken by Cranfield, the muck picked up by the Scottish heli crew, and the new evidence that World Airways picked up engine deposits on a short hop to Maastricht today...?

Obviously The CAA have not either?
