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]
