Sikorsky 1909 Helicopter

In Kiev in May of 1909 Igor Sikorsky began construction of a helicopter. Its failure revealed some of the practical obstacles. Powered by a three-cylinder, 25-hp Anzani engine that drove coaxial, twin blade rotors, the H-1 shook wildly but did not have enough power to lift itself off of the ground. A second machine with a larger engine was tested in 1910, but also failed to fly. He then made a major decision: "I had learned enough to recognize that with the existing state of the art, engines, materials, and-most of all-the shortage of money and lack of experience ... I would not be able to produce a successful helicopter at that time." In fact, he had to wait 30 years before all conditions could be met.
