I read elsewhere that the last time this volcano erupted it went on for a year, from late 1821-1823. Of course, no airplanes in those days!
Also, there is a much bigger volcano which could be triggered to erupt by this one and if that happens we’ll have some global cooling for sure.
What would happen if no planes could fly to Europe for a year?
It sure changes business for our military operations (and our NATO allies) in Iraq and Afghanistan
