The humidity must have been fairly high this morning because contrails were persistent. I noticed these when I went for an early walk and took pictures as they were affected by the wind. The aircraft were an Airbus A320 flying at 17000ft and an Embraer E190LR at 18500ft.
The first photo was taken at 07.18 and the last at 07.34. Sunrise was at 07.32 and the light was constantly changing.
The aircraft were crossing the English Channel and the twisty contrails were over northern France, somewhere southeast of Boulogne. Based on the time and Flightradar24 the most distant ends were in excess of 60 miles from me.
