The Loening C-2 Air Yacht was an amphibious airliner produced in the United States at the end of the 1920s developed from the OL observation aircraft the firm was producing for the US military. It was a two-bay biplane of unconventional design with a tall narrow fuselage that nearly filled the interplane gap. The pilot (and sometimes one passenger) sat in an open cockpit at the top of the fuselage with the engine mounted in front of them.
