Last light over Fiez

Actually, these clouds are the remnants of the "contrails" that don't evaporate. Instead they just hang there all day and dissipate over the course of the day, and with a bit of altitude wind you get skies like this. It did attract my attention that the "contrails" were making a large grid like noughts and crosses. I actually wanted to get a picture of it, but wasn't at the right places and running around not getting any Blip time.
