Detailed operating instructions for Do 24T-1 and Do 24T-2 Variants of the German three-engine flying boat, designed in the 1930s by the Dornier Flugzeugwerke for maritime patrol and search and rescue purposes. With monochrome industrial photography and two colour line drawings and charts throughout, this is a very interesting factory manual for a rare aircraft of which a total of 279 were built among several factories from 1937 to 1945.
