United States Army Air Force footage of a helicopter designed by Emile Berliner and Henry Berliner being tested in Washington D.C.,United States. This was one of the final Berliner models built, if not the final, constructed after the triplane model 5 variant that had been demonstrated in February of 1924. This variant had a biplane configuration and was lighter to improve the thrust to weight ratio. The lower wing generated lift from the rotor downwash due to a high angle of incidence and large camber. The helicopter repeatedly lifts off, hovers, does some forward movement, and then touches the ground.
