1910 Sippe monoplane UK Designed and built by Sippe Brothers and James Jensen
1912. Sydney V. Sippe, who has just qualified for his aviator's certificate on an Avro biplane, at Brooklands, has had a longer connection with the practice of aviation than is generally known. As early as the latter half of 1909, he, with his friend Jenson, constructed a monoplane on more or less " Demoiselle " lines, built throughout of steel tubing, welded together by the oxy-acetylene process. The machine was taken for testing purposes to Addington in Surrey.
