The Junkers J 1

The Junkers J 1, nicknamed the Blechesel ("Tin Donkey" or "Sheet Metal Donkey"), was the world's first practical all-metal aircraft. Built early in World War I, when aircraft designers relied largely on fabric-covered wooden structures, braced with struts and exposed rigging lines, the Junkers J 1 was a revolutionary development in aircraft design, being built and flown only 12 years after the Wright Brothers had first flown the "Flyer I" biplane in December 1903 which used the period's characteristic wood and fabric construction, still widely used for aircraft design at the outbreak of World War I. Herr Junkers' experimental all-metal aircraft never received an official "A" nor an "E-series" monoplane designation from IdFlieg and the then-designated Fliegertruppe, probably because it was primarily intended as a practical demonstration of Junkers' metal-based structural ideas, and was officially only known by its Junkers factory model number of J 1. It should not be confused with the later, armoured all-metal Junkers J 4 sesquiplane, accepted by the later Luftstreitkräfte as the Junkers J.I .
