A German Long‐Range Flying‐Boat: Some Particulars of the Latest Dornier Seaplane to be put into Service on the South Atlantic Route

Although the present type is better streamlined than the earlier machine the resemblance is striking and the stages of evolution are worthy of study. A comparison between this latest Dornier flying boat and the Short machines described in Aircraft Engineering last month brings out some noteworthy similarities and differences in the general design and construction.
