Is it a bird? Is it a plane?

      More blue skies from sunny West Norfolk and for good measure a dash of mackerel sky, complete with a hurrying pigeon high up in the sky in the early morning. Of course that's not the real name for the cloud formation, the real name is cirrocumulus, but let's not get all technical although the idea of naming a cloud formation after the pattern on a fishes back is alright with me.
      Down below but slightly higher up in the sky than the pigeon is a large jet leaving a vapour trail like a paper cut in the blue dome. The black lines? They're just common or garden power cables and telephone lines that give a lovely contrast to the condensation trail way up above.
