Then the other day on the way to work, the sky jumped out at me. Some weird atmospheric event meant the contrails that normally get blown away had, weirdly, been preserved.
Suddenly the sky had gotten interesting. It was like someone had been ice skating on the sky.
It was really weird - there must be dozens of the planes flying overhead every hour. What made these ones special? Why, when it was a bit gusty a ground level could it be so airless up there?
Central London had the same story. I wandered round town with my neck craned up.
London always has had the ability to entertain and delight in unexpected ways. Once again, it had done me proud.
