The Sikorsky S-2 was the second fixed-wing aircraft designed by Igor Sikorsky using the main wing section from the S-1 and a 19 kW (25 hp) Anzani 3 three-cylinder engine in a tractor configuration. During the first flight attempt on June 3, 1910, the biplane reached a height of two to four feet and traveled approximately 200 m (200 yd). After several successful flights, the S-2 was destroyed on June 30 when Sikorsky inadvertently stalled the underpowered aircraft at an altitude of 20 m (70 ft).[1]
