411A, sometimes you vent to the point of sounding as if you are so up your own a*** and lost in your own ego. This is very much an unknown. Geology and geography in particular set this apart from other events; most volcanic eruptions don't cause clouds of ash to drift over heavily populated airspace not do they usually involve erupting through a glacial ice cap. I have it on very good authority from a BA pilot, now retired, with over 30 years experience, most as a captain, that he would not fly if there was any possibility of ash cloud contamination. I trust his judgement more than someone who lives in a rather inert geological zone prone to endless blue sky, despite where else you may have shown off your prowess. His somewhat understated, modest demeanour not to mention skill is something to aspire to.
