Picking up the railway line close to Mayfield, I followed it due south towards Heathfield. For half the distance I could see that it ran through woods, for the moon was rising, and gave us a slightly better view of what lay below us. When just over Heathfield Station the searchlight from the anti-aircraft post on Brightling Beacon again shot up suddenly, and in a few moments was upon us. I was flying quite leisurely, and banked so that they might get another good view of the rings on my planes. They evidently recognised me through their glasses, for very quickly they shut off their light and I continued, finding my way by the coloured signal-lights of the line from London to Eastbourne. The land beneath us was low-lying and pretty level. There, before me, I saw a few half-obscured lights denoting Hailsham town, then the railway lights of Polegate junction came into view, and still farther in the distance the row of scattered lights, some of which were moving, denoted the position of Eastbourne. The authorities may make all sorts of complicated "lighting orders" with power to the police to enforce them, but it is next to impossible to black out any even moderately populous area. While a hundred residents will effectually darken their windows, there are the few thoughtless ones who burn gas beneath their skylights, or who do not sufficiently cover one window--often a staircase-window--or servants who go to bed neglectful to draw their curtains across the blinds. Then there are shaded street lamps burning at dangerous corners, or at cross-roads, and these, provided the ground is wet after rain, reflect a zone of bright light which acts as an excellent guide to aviators aloft. In the increasing light of the moon I made out the big gasometers of Eastbourne which stood out as a landmark in the direction of Langney, but, leaving them on my left, I steered a course for the coast over Willingdon Hill, my altimeter again showing 2,800 feet. I flew slowly and leisurely for fear of our anti-aircraft guns. As I expected, a few moments later the listening-post on Beachy Head, having heard my approach, was instantly on the alert, and the beam from their searchlight shot up, searching slowly about for me, because at that moment I had run into a bank of cloud and became obscured. We were suddenly both enveloped in darkness, our only light being that little bulb set over the map. Still I kept blindly on, hoping to get out of it quickly. Yet the moments seemed hours as we went along. I increased the speed, but so long were we in that damp obscurity, that I knew that we had entered the cloud at its greatest length.
