SOME FLIGHTS OF MY OWN 135 Gotha. I felt sure of it from my memories of what I had studied in my maps. Gradually I ascertained how far before the front I could keep my machine without losing height or exposing myself to over-violent squalls, and flew onward for a whole hour, keeping a south-easterly course. I now began to feel discomfort from the water that had rained down on my hair, head and neck during the previous heavy showers. My teeth chattered audibly. How long was this flight to go on ? It went on regularly and steadily. Such minor troubles, I thought, must often occur to pilots who fly long distances overland in power-driven machines, and so I held on my course to the south-east. Often mighty clouds gathered in front of the rain storm, I flew round them but was sometimes compelled to push through them. However, I soon found that I was managing this blind flying better than at first. As far as I could make out, the towns over which I flew must have been Erfurt and Weimar, but I am not sure. Then the front bent sharply to the south. It was already late. Visibility was bad and grew steadily worse. Darkness fell and I began to think about getting down. Wide plains stretched before me partially wooded ; I was over unknown country. I knew that the storm behind me must follow and therefore I looked out for some building where I might conceivably find shelter for my machine after landing. A town came into sight, with a fine field for landing just outside it and a big factory close at hand. I dropped down a bit and examined the whole situation carefully once more. The flags of a Gymnastic Festival which was being held there gave me an excellent idea of the wind's direction, and I could hear the shouts of the people. After a short glide I landed in Hermsdorf, not far from Gera, and nearly ninety miles from the Wasserkuppe. II A BLIND FLIGHT IN A SOARING PLANE The Olympiad was drawing to its close. As regards the science of flight, it had taught us something new as
136 KRONFELD ON GLIDING & SOARING Hirth's and my own first deliberate flights with thunderstorms had demonstrated the possibility of utilizing the forces of the elements. Nevertheless we were not too well satisfied because we knew that not everyone would be capable of responding to the challenge of the thunder ; moreover, the typical weather which this kind of flying demands is not very prevalent. If distance flights were only to be undertaken by the aid of thunderstorms, they would have to remain exceptional performances. Early on " record day " no flights could be started. Fog lay heavy on the Kuppe, and the weather appeared hopeless. The fog having lifted a little, the first man started soon after eleven ; but I still waited a while, for my " Wien " climbed so well that I should have flown up into the low drifting clouds immediately. For almost an hour the others wheeled about on the western slope. It was a glorious sight. When at last I started, a whole squadron of soaring planes hung at the same height above the Kuppe ; then they all climbed. I decided to overtake them, one after another, and outsoar them. For a while we frolicked in close proximity, then we strove to climb again. From the north-west a great bank of cloud came drifting towards us, and some of the machines flew to meet the first big cumulus. Flying under clouds had become a normal practice, and all pilots were skilled in it. Suddenly I saw two planes disappear almost simultaneously into the deep, drifting, ragged masses. Matters did not look exactly encouraging, but there was not much time for consideration as the very next moment I found myself in the midst of the white milk-soup. Should I push down again ? It certainly seemed advisable. Of course I had left my parachute behind this time ! There had been no signs of any approaching thunderstorm. The altimeter was rising. On the other hand it went against my flyer's pride to struggle down, so I carried on with my climb into the white infinity. Once more the compass began its strange circling movements, and the moisture was even heavier than during my recent thunderstorm flight. The speed indicator swallowed water and refused
