Such a strange week. Our house lies directly under a flight path between two big German airports, so normally the sky is a criss-cross of jet trails. In the past week, the skies have been silent and blue.
No white streaks across the sky during the day; no flashing lights at night, marking the path of an airplane across the black sky. And no noise. Not that you notice it, mind. You barely register that it's there - until there are no planes at all and it might suddenly occur to you that it seems a little bit quieter.
But yesterday evening and today we noticed the first jets scratching the clear blue sky.
Business as usual, it seems.
