All winter, I've been grumbling about the number of flights over my part of North Kent. The Air Traffic Authorities must have changed the flight path to Gatwick Airport. The jets fly so high that I can't hear them, but the nasty vapour trails they leave in the blue sky offend me. One morning, a couple of months, back I counted 13 of them.
Well, courtesy of the volcano in Iceland and grounded aircraft my sky is temporarily vapour trail free !
