Has the givernment done anything to get the UK tech experts together on what is the low ash risk threshold. The UK may have more expertise on this than any other country: BA, other airlines, RR, the Met Office Unit (VAAC), CAA, NATS and no doubt some other UK experts.
I'd hope they are all meeting first thing tomorrow, if not already.
There seems a big silence.
Of course you could do this on a European level - but you can't fly anywhere!
