I was going to title this post 'Poor Visibility" - an Eyewear title if ever there was one - but went for the more theologically resonant one instead. Odd times over the European skies today - ash is general over England, and beyond. There was a large volcanic eruption in Iceland on Wednesday. Due to the weather conditions, a plume of volcanic ash has now spread southwards towards northern Europe and is severely affecting all airlines' flight activity in the area. For safety reasons and on the direction from Air Traffic Control Service (Nats) a decision has been made to cancel a number of flights and close all London airports. All British Airways domestic services have been cancelled on Thursday 15 April. On the BBC, they are talking about maybe no flights until Saturday, unless the ash plume, now pretty immobile, moves on. This seems relatively unprecedented, and more than a little sci-fi slash disconcerting. No eye in the sky, indeed. Iceland's revenge on Britain for the banking crisis?
