The 1929 Stinson SM-4 Junior was a special retractable-gear, high-wing two-place cabin monoplane endurance plane, Sally Sovereign, developed from SM-1 NX9696 and powered by a 300hp Wright R-975 engine. It was damaged in a wheels-up landing after a failed endurance flight, piloted by Eddie Stinson and Randolph Page.
It was rebuilt with fixed gear as K of New Haven for an aborted attempt at a US-Argentina non-stop flight on 7/15/30, when the crew became lost in a fog over Georgia and ran out of gas. They bailed out and the SM-4 crashed to destruction.
