Dornier Do X

12-engine flying boat, the largest, heaviest, and most powerful flying boat in the world when it was produced by the Dornier company of Germany in 1929.

Here she’s shown during her display flight from Friedrichshafen, Germany, to New York, USA, with a stopover in Natal, Brazil, which lasted 9 months, from November 1930 to August 1931, due to a wing fire in Lisbon, Portugal, among other things during the trip.
