But when the ash cloud from
How much have we learned from that experience and what happens when Eyjafjallajokull or one of her equally volatile neighbours decides to blow their top again? My colleague David Learmount spent last week at a conference on the effects on the volcano on aviation and came away with some slightly downbeat conclusions.
Our knowledge of the effects of volcanic ash remains an inexact science, he says in a Comment piece in this week's issue. Secondly, allowing airlines to take their own decisions whether to fly through low-level volcanic ash, based on available data, as they do with extreme weather, would require a massive mindset change among regulators from pure risk aversion to risk management. Not very likely.
