It appears that due to commercial pressure from airlines, the resolve is beginning to crack.
It will be interesting to see how history judges this albeit continuing situation.
My totally unqualified judgment, based simply on the both appalling and laughable history of the MET Services and the crippling, pathetic directives from the Health and Safety bodies, that this will collapse, thrashing its little legs, straight into the same little box.
Belgian F18 or ASAF F16's apart, lets wait and see what "catastrophic" effects occur to the rapidly increasing number of civil aircraft currently ploughing their weary way through the "Volcanic Cloud"
Any down yet ???
