Wide angle shot of the clear blue sky over this part of Germany today. It's been like this, without a contrail in sight, for a couple of days and nights now since all the flights were grounded due to the volcanic ash cloud. It won't be much longer before the many thousands of people who've had flight plans disrupted and the airlines that are loosing tons of money find a way to start flying again, but while they're grounded there is at least one small benefit for the rest of us.
