please read my post nr 817. There are ALWAYS AND EVERYWHERE volcanic ash particles in the air. The ash concentration is never zero. Does that mean that airplanes should be banned from flying all over the world?
The problem is that no lower level acceptable ash concentration has been defined and decision makers are greatly overreacting.
