Pilots Arms Next time you have the opportunity look at your pilot's arms. The arms are not strong in an obvious sense. You would think that the particular part of the hero-body that with literal single-handedness guides hundreds of tons of metal and humanity would be well-formed, masculine and muscular. In fact, these very arms countering fears of passengers actually appear weak, almost stick-like. The elbow seems to drop from the shoulder unsupported, without the expected thigh-sized bicep. The short sleeve appears large and underfilled. There are tendons strongly connected from the core without strenght, but filled with confidence and grace. In place of muscle there are highly developed nerves in the elbow and shoulder that firmly connect with the brain and the art of flight.
