Sikorsky S-2

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 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 yd. After several successful flights the S-2 was destroyed on June 30 when Sikorsky inadvertently stalled the underpowered aircraft at an altitude of 70 ft.
