Book excerpt: In the mid-1930s, contracts were placed with Dornier and Junkers for prototype four-engined strategic bombers. The Junkers aircraft, the Ju 89, was by far the better of the two. However, the program was abandoned in 1937 and Junkers used parts designed for the Ju 89 to construct a new civilian type for Lufthansa. The wings, tail and engines of the Ju 89 were added to a new fuselage to create the Ju 90. The 40-passenger aircraft flew for the first time in August 1937 and entered Lufthansa service in 1938. A production batch of 10 aircraft were ordered. Two Ju 90s were also ordered by South African Airways but were never delivered because of the war. The Ju 90 was pressed into military service with the Luftwaffe, first as a transport during the Norwegian campaign and later flying supply missions to the beleaguered German forces at Stalingrad. The more widely used Ju 290 was developed as a result of the rebuilding of early Ju 90s. This book covers the antecedents of the Ju 90 as well as providing a comprehensive account of its design and construction. Its operational history, both military and civilian, is discussed. The book contains many detailed photographs of the aircraft and the various types of engine used.
