[1] The C-2 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.

[1] The C-2 was produced in two versions, the C-2C with a Wright Cyclone engine and the C-2H with a Pratt & Whitney Hornet.

[2] One C-2C, modified from an OL, was flown from New York City to Bergen by Thor Solberg in 1935, the first flight from the United States to Norway.

[3] Solberg christened the aircraft Leiv Eiriksson and used it to roughly re-trace its namesake's journey across the Atlantic (albeit from West-to-East, and by air) via Greenland, Iceland, and the Faroe Islands.
