The first flight of the giant twelve engined Dornier Do X [Germany, 1929]
A picture of the first flight - 12 July 1929 - of the original Dornier Do X. No markings were on the machine. Here it makes full use of the cushion effect when flying low over the water of the Bodensee.
The text quoting that the Do X is here flying with 169 persons is later added for publicity reasons I think.
