Vapour Trail Galore!

11°C  -  8 mph SSE Wind Speed  -  12 mph Gusts  -  Sunny Intervals.  When walking round to the Corner Shop at mid-day I saw these vapour trails  -  not a plane in sight!  Usually I see only one vapour trail with a plane  -  looks like a demonstration of some sort must be going on  -  will have to keep my eye on the news.
