Kaman H-43 Huskie
The engine of the HH-43F Huskie drives twin inter-meshing rotors that cross above the fuselage. It has a tail and large, rear-facing fuselage door.
The H-43 was designed extremely compact because it's inter-meshing rotors. Between 1958 and 1965 some 365 were built.
By late 1960s well over 200 H-43 Huskie turbine-powered rescue helicopters were serving with the USAF.
