SOARING PILOTS REPORT 113 me in the dark lay a ghostly greyish-white level stretch which I knew to be the dunes, while a darker area beyond them I recognized the water of the Kurische Haff. It was impossible to calculate height ; below me I saw vague human figures in the darkness, and now the time began to drag. Every moment I expected to find myself in collision with a sandhill ; the breeze freshened and I gradually lost all feeling for the position of my machine. The open seat gave me no help ; I had to do my best by noting the position of the curved border of the wings, which were edged with bars of hickory wood that showed up fairly well against the sky. From time to time Captain Rohre enabled me to gain some idea of my height by striking matches, and at last the desired ground lights made their appearance in the shape of petroleum stable lanterns. But they were hardly in action a moment before they were blown out by the ever-freshening breeze, which was now blowing at a velocity of sixty feet a second. They were lit again and again till all the available matches were used up, but only one lantern remained alight. Many were buried beneath the drifting sand that the wind drove over the dunes. Magnesium flares were now lit, but their light was too glaring ; they dazzled me so much that I could hardly maintain my position in the air. At last there came fresh and reliable help in the form of electric pocket torches which had been procured from the village of Rossitten. Then new boxes of matches and supplies of petroleum arrived, so that there was enough material to keep the ground illuminated all through the night. The valiant members of my aerial police force grew hourly more accustomed to their work ; I, too, was getting more used to this night flying. Towards midnight the full moon looked out now and then through the clouds which covered the sky, and in its pallid light the sandhills assumed grotesque shapes. After the moon had finally withdrawn behind the cloud curtains, the night seemed as if it would never end. From below the watchers tried to call up the time to me, but their voices were swallowed by the wind so that I could not understand a word. How slowly the time passed ! And then there came yet
ii4 KRONFELD ON GLIDING & SOARING another trial of my endurance rain ! It was an unspeakable relief when at last it ceased and the grey dawn announced a new day. Muffled shapes the watchful sentries on the dunes became visible. And now the time passed more quickly and flying grew easier. I breakfasted. At last I had flown as long as the holder of the former world record. Half an hour later my control lever broke. The good glider which had endured so well with me through the stormy night landed me at three minutes past six on October aoth, 1929. I thanked God, who had so graciously helped me in my need. OUR FIRST SOARING FLIGHT IN AMERICA By P. LAUBENTHAL Cape Cod ! The name conjures up in my mind our wonderful experiences' in a beautiful warm New England summer on the Atlantic coast of America. As I pen these words, only three months, but four thousand miles separate us from the golden slopes of the sandhills of that peninsula. It so chanced that its position made it the starting point of American history, and it afforded us flyers the best opportunity we had ever experienced in the history of Soaring Flight. " Where the pilgrims found maize the German gliders await insurance," wrote our friend D. Rochford, a true flying enthusiast, in his Boston paper soon after we had settled down on Cape Cod. His words sounded an impatient note and yet they were comprehensible to the expectant American readers who read with growing interest the reports of our arrival on the New England coast and were eager to hear of a record flight in a motorless aeroplane. The discovery of Cape Cod for our motorless flying was due to chance and the kind endeavours of a Boston friend, who was a member of the North German Lloyd. Here on this coast lay the first settlements of the Pilgrim Fathers, those stern Puritans who gained a footing there
