10 Dollars Dornier Do X

The Dornier Do X was the largest aircraft in the world when it flew in 1929 — a twelve-engine flying boat that carried 169 passengers on a demonstration flight over Lake Constance, a record that stood for decades. Its transatlantic voyage from 1930 to 1931 was plagued by fires, mechanical failures, and a nine-month delay in the Canary Islands. Only three were ever built, all for different operators, and none survived the war.
