this is a link to the 2011 update post with the eruption of Grimsvotn

was there a government over reaction to the iceland volcanic eruption ash cloud, probably so really, with millions if not billions of revenue lost for the air travel industry, then test planes went up, even british airlines flew through the icelandic volcano ash in the north atlantic and it seems the british airways plane suffered no real ill effects.
