That is an entirely reasonable position. The trouble is that your earlier posts all default to the presumption that there has been an over-reaction, so your last post rings hollow.
Given that, like one or two other posters on this thread, I used to fly around visible ash clouds in other parts of the world (e.g.Alaska, Indonesia), I must, I now realise, have flown 1000 miles downwind of active volcanoes through invisible ash clouds on numerous occasions. Sorry about the scratches on the engines Lord King!
