The first successful airplane took off in 1903 in North Carolina.

The first successful helicopter that could safely be controlled in turns, hovering and level flight was developed by Igor Sikorsky in the 1940's.
The first helicopter might be built in Ukraine (1909) by Ukranian engineer Igor Sikorsky (1889 - 1972) but it was more than 25 years before early practical machines - like the VS-300 were flown in prewar trials.
