This was taken just off the M1 north of Luton Airport which I guess explains the number of contrails... couldn't block the sunset but seemed to splice the sky...
Thank you so much for calling by - it warms the cockles of my heart :) Mwah
Love that tracking across the sky, I'm always amazed on a clear sky day how many planes pass over. All above the clouds in the winter more but stilll there winging their way to other places.
