Salto Travel on Europe could not compete with the Clippers. The Short Company of England built the Empire flying boat to carry mail and passengers across the Atlantic. When Pan Am decided to compete in Europe and the Atlantic in the late 1930s, the Empire was no match for the Clipper. The German flying boat effort culminated in the Dornier Do X, a plane with twelve engines and capacity for 169 passengers. Its maiden voyage in 1931 was unsuccessful, and the plane became a museum piece. The Russians built the largest plane of the era, the Maxim Gorky with eight engines and a 210-foot wingspan, which crashed in 1935, killing all forty aboard and raising the question of the value of such large aircraft. In the late 1930s Donald Douglas’ DC-3 was the dominant aircraft. Salto Travel 2016.
