The first successful helicopter flight is credited to Paul Cornu, a French engineer, who flew his design in 1907. However, it was Igor Sikorsky, a Russian-American aviation pioneer, who significantly advanced helicopter technology and is often recognized for creating the first practical helicopter, the Vought-Sikorsky VS-300, which flew in 1939. Sikorsky's innovations laid the groundwork for modern helicopter design.
