History

Based on the S-35, the first S-37 was built for Rene Fonck to attempt a non-stop Atlantic crossing and was completed in spring 1927. When Charles Lindbergh won the prize the attempt was abandoned and the aircraft was converted into a passenger airliner.

Variants

Two were built, both completed in 1927. The first had 500 hp Gnome-Rhone Jupiter engines, later exchanged for 525 hp Pratt & Whitney Hornets. Late in 1927 the second was developed with Consolidated Aircraft as the S-37-2.

Where you'll see it

Renamed Southern Star, the first aircraft was sold to American International Airways of Argentina. On 30 June 1929 it became the first commercial transport to cross the Andes between Buenos Aires and Santiago, carrying 5,100 pounds including eight people. It was later with Pan American and was scrapped in 1930.
