Junkers T 29 description as the T 29, suggesting a training role and a hope of sales, they seem to have been built primarily to flight test the double wing which was successfully used on later Junkers aircraft such as the G 28, the Ju 52/3m and the Ju 87. Junkers T 29 The Junkers J 29 was a two-seat, single-engined experimental training monoplane, built in Germany in 1925. Its significance is that it was the first aircraft to fly and test the Junkers Doppelflügel (double wing) control surfaces used very successfully on the later Junkers Ju 52. The Junkers J 29 was

It is also thought that the contrasting promise of the advanced, low drag features of the Junkers monoplane aircraft designs, versus the Junkers firm's usage of experimental non-traditional sheet metal materials, and the firm's habit of almost constant experimentation obstructing any future hope of producing its advanced designs for the "Luftstreitkräfte", compelled "IdFlieg" to create the "Junkers-Fokker Aktiengesellschaft", abbreviated as "Jfa" and pronounced as if spelled "iefa" in German, on 20 October 1917, to allow Anthony Fokker, who even flew one of the J 2
