Eugen Bönsch was one of the most successful fighter pilots of the Austro-Hungarian Army in the First World War.
He joined the Austro-Hungarian army as a volunteer in 1915. After basic training, he was transferred to the aviation groups at his own request. Initially, he was a mechanic with the
Fliegerersatzkompanie 6 in Wiener Neustadt, until he was trained asa field pilot in 1917 in the Fliegerersatzkompanie 8. He was then assigned to the fighter company Flik 51 near
Haidenschaft, where he remained until the end of the war. Towards the end of the war, Bönsch’s unit was increasingly used for infantry support. During the Battle of Vittorio Veneto, he won several air victories despite the overwhelming superiority of the Allied air forces.
After returning home, Eugen Bönsch ran the Wiesenbaude and had the gliders Wiesenbaude 1 and Wiesenbaude 2 manufactured by Edmund Schneider.
During World War II, he was drafted into the German Air Force as a captain and was
commander of Oschatz Air Base in Saxony.
Ski sailing at Wiesenbaude
By Herbert Beutel
Probably no other mountain range in Central Europe was as ideal for ski sailing as just the undulating high plateau around the Wiesenbaude in the Giant Mountains. And yet decades had to pass before this pioneering work was a complete success was.
It was the year 1929. At the Wiesenbaude, a new sport came into its own. My Uncle Eugen Bönsch, the well-known fighter pilot of the First World War, flew his gliders over the heights of the Krkonoše ridge and formed with the later famous Edmund Schneider from Grunau near Hirschberg, the builder of the first Wiesenbauden gliders, and a Prague flight instructor the first gliders . I was also one of the first certified glider pilots and thus got a special interest in updrafts and downdrafts as well as wind pressure on slopes. That's how I came up with the idea of flying not only sailing, but also on skis to sail. Under the guidance of my experienced flying uncle, I built the first Ski sailing apparatus. It consisted of a carrier frame, a kind of backpack frame, on which two wings - butterfly shape - made of plywood panels movable: which I attached with handles with outstretched, lateral horizontal arms. Old beginnings were difficult, and many a grand piano broke and buried me under its ruins. New grand pianos have been installed in various sizes are constantly being built. At that time I was mockingly called the Amorherbert. By chance I found two huge and strong bamboo poles on the ground, at the end of which rings were still attached. My uncle Emil Bönsch, who already decades before me on the Wiesenbaude, I was able to find this mysterious find. explain. None other than Privy Councillor Dr. Weinhold from Breslau, a loyal, dear and esteemed guest of the Wiesenbaude until his old age, had thus built his first ski sail decades ago. It was a triangular sail of huge size, and probably Rübezahl himself could have been successful with it. However, I gave these two poles, which have a long slumber on the meadow chalet new ideas, new courage and hope.
Since the gliders "Wiesenbaude I and II", the "Krummhübel", the "Burkbraun", the two-seater "Bad Warmbrunn" in peaceful Flight over borders, well-known planes also came to the chalet. Wolf Hirth landed near the Meadow Chalet, and the world record parachute pilot Lola Schröter landed in a parachute at a mountain gymnastics festival at the Wiesenbaude. Lola Schröter procured me light metal rods from an aircraft factory and a Berlin canvas manufacturer the canvas for covering the sail. It was created the first sleek, light and handy ski sail "Wiesenbaude l".
Rübezahl probably faced every new beginning with a rumble. He defended itself with its forces for a long time when intruders from valleys and cities and children of his mountains dared to enter into his sanctuary and quiet mountain kingdom in the human onslaught. Planes also crashed, gliders ski sails fluttered, avalanches rolled, and athletes of skiing often got into serious mountain distress. But Rübezahl probably reconciled with everyone, and mediators became his mountain children, who quietly and modestly continued their austere and austere life in tireless and active creative workn loving and thus opened up Rübezahl's empire, which is the source of power and the fountain of health of so many people.
So our ski sailing after many failures still had a considerable success. From the north, east and west, Rübezahl's pressure winds flowed with undiminished power to the high plateau, and soon we were riding with the right ski sail like Rübezahl's goblins around, and many a skier will have believed in spooks when we fog scurried past him like ghosts.
Our tried and tested sails had a size of 3.5 to 4 square meters. The were welded together in a T-shape, at the ends of which there were also rings to hold the stretched canvas in place. The screen was labeled, and so we already had a small regatta of 4 ski sails.
In the lee of the large meadow chalet we went to the start. The skis in lighter Stem position, they were already fighting against the first wind pressure. Skating we now went into the full wind, which with increasing speed driven. It was not easy, at full speed and with the strongest wind pressure to get the sail off the body (back). This had to be done in a jerky manner in order to to let it flutter in the wind, holding it up with the left or right hand. This moment was always given at the blowing edge at the summit of the Brunnberg. At full speed, holding the sail high and letting it flutter in the wind, around the Amalienruh', the summit landmark of the Brunnberg, in order to downhill again. If you missed this moment at the Blowing edge, you were chased at flying speed against the Blaugrund. Then serious and painful falls were inevitable. But soon we had the big arc out. We also learned how to cross and rode along, against wind as well as across the slope. This was probably the most dashing and courageous phase while ski sailing. With tailwind to the Amalienruh', we went into a shooting trip after turning downhill again. Halfway down the slope, an elongated Kristiania was turned, threw at that moment the sail was again half-sidedly on its back and crossed at full speed up the slope, with the body not to, but from the slope lying in the strong wind pressure of the sail, so to speak. If the wind pressure left only a little there were also serious falls.
My loyal regatta mates were the ski instructors of the Wiesenbaude, of whom Otto and Gustl Berauer in particular masterfully and perfectly mastered ski sailing with great skill. Otto Berauer reached a stopped speed of 90 kilometres per hour in hoarfrost snow, and Gustl, took 5-7 skiers on the rope with his Rübezahl forces. We drove through the Heinrichbaude-Wiesenbaude route (3 km) with a tailwind in three minutes. After every longer start, you had an unusual muscle soreness of the back muscles, which are probably the most used in this sport, . In a gratitude that runs through my whole life, I remember today especially of my best and most loyal mountain comrade Otto Berauer, the Son of the mountains and true comrades in many a difficult hour of mountain distress.
