The S-34 was a sesquiplane amphibian with a boat hull, being powered by two tractor 200 hp (149 kW) Wright Whirlwind J-4 engines.[1] It had a boom-mounted twin-rudder tail unit and room inside the hull for five passengers.[1] During a test flight in November 1927, one engine failed and the S-34 crashed and sank. Igor Sikorksy and the others on board escaped without injury but the S-34 was destroyed.[1] It was the first Sikorsky aircraft with a boat hull and would lead to a family of similar flying boats and amphibians.[1]
