Cargo being loaded aboard the cabin of an autogyro

Two men load cargo into cabin of a aircraft (autogyro) that appears to obtain lift, from two coaxial counter-rotating large wings atop the craft. The "wings," or rotors, are very wide, and contain moveable flight surfaces (ailerons). Forward thrust is provided by an unenclosed radial engine driving a large propeller. The hybrid helicopter autogyro aircraft is also equipped with empennage. It is parked in a fenced area. A considerable amount of cargo sits on the ground, ready to be loaded. Scene shifts to possibly unrelated image of an unkempt man wearing a headset.
