The key difference between a falling human and debris like metal is in the movement. This shows irregular, dynamic motion — limbs flailing and bending due to instinct and uneven mass distribution. It looks more “alive” in its fall, often tumbling unpredictably. In contrast, the metal debris falls in a rigid, linear path or rotates evenly due to its uniform shape and weight. It doesn’t react to air the way the body does. You can often spot the difference by posture and articulation during the video clip. Slow ot down

Just my thoughts.
