Sky writing, sky fighting

      A wonderfully clear morning late last week and somebody's fighter jets were up on high burning fuel, making a noise and practising.
      Three vapour trails came across the sky from west to east travelling high and at great  speed, seemingly two chasing one.  The outer pair of aircraft caught up with the aircraft in the middle and the noise really started. Then the occasional Fenland soundtrack was really under way.
      We raced inside the house to grab the binoculars and the aircraft have gone, just dissipating vapour trails high up in the sky was all that remained.
      Fifteen minutes after that and the clear sky had changed completely and it gradually filled with cloud until we had a lovely grey afternoon to enjoy.
