Photo: shot a little late, it only took a few minutes for the full effect to be lost. Moments before, shen I decided to stop the bike there was a clear cross in the sky, those high altitude cirrus clouds had a swathe cut through by a flane, it’s vapour trail was the cross and the wake was clearly visible too. The plane itself was long gone, but the effect was quite striking- take my word for it!
