Question: Who designed Hans Klemm's first light aircraft? Passage:Hans Klemm's first light aircraft was the Daimler L15 and the L20 had much in common with it. Both were cantilever monoplanes with twin open, tandem cockpits and engines of very low power. The L20's low wing distinguished it from its predecessor and had the advantage of providing a low centre of gravity and better view during the landing approach as well as better protection for occupants in case of crash landings. The low-set wing also allowed a shorter undercarriage on the L20, which was otherwise like that of the L15 with the wheels independently mounted on pairs of centrally hinged V-struts and with vertical shock absorbing legs to the wing underside. Wheels were sometimes replaced by floats. Intended from the start for serial production, the L20's structure was simplified, with a pentagonal cross-section fuselage lacking the L15's rounded upper and lower surfaces. The fuselage was wooden framed with canvas covering. The overall strength of the structure, which had a safety factor of 12, was emphasised.

question:
Question: Which European opera company presented by DGOS has been in operation for the greatest amount of years? Passage:The Dublin Grand Opera Society (DGOS) was founded in 1941 by Captain (later Colonel) William O'Kelly and a group of opera enthusiasts with John McCormack as its patron. The shows were cast with local singers and a volunteer chorus. Initially the music was provided by the orchestra of the Irish Army music school, and later by the Radio Eireann Symphony Orchestra. The Society put on two one-week seasons of opera throughout the years of World War II. After the war ended the DGOS presented performances by European opera companies such as the Opera-Comique, Hamburg Opera and the Netherlands Opera. From the mid 1950s to 1966, the Society, concentrated on Italian opera with the help of sponsorship from the Italian government. During that time numerous Italian stars and rising stars of the day appeared there, including Luciano Pavarotti who sang in Rigoletto, La traviata, and La boheme. The Italian sponsorship ended in 1966, but the Arts Council of Ireland and the Bord Failte (Ireland's tourist board) continued to provide guarantees for any financial losses. New opera companies were brought in, including the Romanian National Opera and the Prague National Theatre.
