1922 - First helicopter prototype

At College Park, Maryland, Henry Berliner demonstrates the first (though disputed) helicopter prototype by combining a Nieuport 23 fighter’s fuselage and a Bentley 220hp engine. They are connected with geared shafts to two horizontal rotors mounted on a truss extending sideways from the fuselage. A third horizontal rotor at the rear enables pitch control.
