SOME FRIEDRICHSHAFEN "MILESTONES"
"The F.F. 34
is of the pusher type, like the 31, but it has two plywood fuselages carrying the tail instead of the open tail booms of the 31. The machine, which is shown in Figs. 15 and 16, was fitted with a 240 h.p. Maybach engine, and as the engine was placed in the rear of the nacelle, the field of fire in a forward direction was very good. It was used as a reconnaissance machine, and was equipped with wireless.
