Original Note:
Experimental helicopters have been flying since the early 20th century, properly functioning helicopters were around since the 1930s. Your picture shows the Vought-Sikorsky VS-300 in September 1939, which achieved several firsts, but was not THE first helicopter. https://en.wikipedia.org/wiki/Helicopter https://en.wikipedia.org/wiki/Vought-Sikorsky_VS-300
