A lot of nervy scaremongers have gone very quiet. Now why would that be?
They had all the plausible arguments for the huge risks and dangers attached to going flying within 1000nm of that wicked volcano.
Many of us have operated within 25nm of active volcanoes in theatres of operation like Indonesia, Sicily, and Iceland. Not forgetting Mexico and Western USA/Canada.
I suspect there's not a professional pilot among the naysayers who have suddenly gone mute. And the truth is that there's nothing they resent more than opinions from opinionated pilots which concern operating commercial aircraft. Chumps!
