WEFT is AircraftIQ's four-point recognition method — how it works.

Spot it by:

Unmistakable: an enormous two-deck flying boat hull with twelve engines in tandem pairs above the wing, large lateral sponsons replacing floats, and a parasol high wing — nothing else looks like it.

History

First flown in July 1929, the Do X briefly carried 169 passengers on a demonstration flight. Three aircraft were built — one for Germany and two for Italy. The Do X made a transatlantic crossing to New York in 1930–31, though plagued by technical difficulties. No commercially viable route was established and all three aircraft were eventually scrapped.

Variants

Three aircraft were built; the two Italian machines (designated Do X2 and Do X3) used Fiat engines rather than the Curtiss Conquerors of the original.

Where you'll see it

Never entered regular commercial service despite the transatlantic demonstration; all three examples were retired by the mid-1930s.
