The BGA Comes of Age On 4th December, 1950, the British Gliding Association will be 21 years old. It was on that date in 1929 that the historic "Gliding Lunch" was held at which the Association was formed. Many people who are gliding today have little or no idea how the gliding moverru:nt started in this country, or even how soaring flight came to be established at all as a possible and worth-while accomplishment. Its existence is taken for granted. From the few seconds' hovering by Otto Lilienthal in )895 to the 91 minutes achieved by Orville Wright in 1911, most ofthe very few soaring flights made by man were done in order to learn the art of balancing in the air, in preparation for power flying. Then, during the period from 1919 to 1922, when treaty restrictions prohibited the building or importing of aeroplanes in Germany, soaring flight began a course of development in that country which has led to its present world-wide status as a fascinating scientific sport. Wolfgang Klemperer beat the 1911 record with a flight of IS minutes in 1921, Arthur Martens first soared for one hour and F. H. Hentzen for 3 hours in 1922, Max Kegel climbed into a thunderstorm in 1926, and in 1928 Robert Kronfeld came on the ~ne to liberate soaring flight final1y from its confinement to the windward slopes of hills. The yc:;ar 1929 was, with the possible eXGeption of 1922, ,the most notable in soar41g history, mainly owing to Kronfeld. On 14th April he set up an altitude record of4,183 feet, on 15th May he made the first flight ofover lOO km., and on 30th July he raised the record to 8,494 feet and soared 93 miles from the Wasserkuppe to Bayreuth. The fame of these and Qther flights spread far beyond Germany, and on 6th November, 1922, The Aeroplane published a special "Gliding Number" to publicise the new knowledge. Among the flood ofletters which it brought to its Editor, there was one from Mr. D. C. COlver, an ex-pilot ofthe first world war, suggesting a luncheon party at which all those interested could meeL The party was held on 4th December at the Comedy Restaurant in Panton Street, and 56 people turned up, including Mr. C. G. Grey, then Editor, and Mr. Thurstan James, present Editor, of The Aeroplane. Mr. Culver, from the chair, started by suggesting the formation of a gliding club, whi\:h would start op.:rations by buying a Zogling Primary from Germany; but by the time the meeting broke up at 4 p.m., its ambitions had run to electing a provisional committee for a "British Glidi:lg Association," with him as chairman and the late Mr. Howard Flanders as secretary. The new Association started with a flourish and a great number of gliding clubs were formed, but many ofthem soon collapsed, often by crashing their only machine. This was followed by a few years in the doldrums, when the movement was with difficulty kept alive, but it picked up again ill 1933, when a substantial amount of soaring began to be done. A Government subsidy was offered in 1934 on condition that certain differences ofopinion within the movement as to the constitution ofthe B.G.A. were resolved, and as a result this constitutiOn was altered in 1935 to something resembling its present form. Since then, apart from a war-time adolescent period of suspended animation, the B.GA. has been run by gliding people for gliding people; it therefore enters adulthood travelling along the right road. But the part played by the present Chairman in setting it on that road sixteen years ago is probably unknown to more than one or two people still active in gliding, so relentlessly does the personnel ofthe movemen~change with the years. Even the Editor of this journal, though a founder member of the London Gliding Club in February, 1930, did not quite make that Gliding Lunch twenty-one years ago. -117- Here and There American Contest New British Altitude Records The 17th National Soaring Contest, held Flight Lieutenant A. W. Bedford, of the at Grand Prairie, Texas, was won by Dick Empire Test Pilots' School at Farnborough, Johnson with his new RJ-5 sailplane. He climbed 19,118 ft. and reached 21,338 ft. exceeded both the national goal and above sea level in an Olympia on August distance records with a 337-mile goal flight 24th. He thereby broke four official across Texas.
