In motorsports, everyone is eager to outrun others, and even when winning by 0.01second, a racer can be showered in fame and honor on the other side of the finish line. Decades ago, engineers of Airbus discovered that sharks were able to be crowned as the top predator in the ocean because of the special structure of their skin. This feature has helped sharks withstand resistance in the water for them to be as fast as lightning. Inspired by sharks, engineers contemplated on ways to apply the same mechanism to planes, vessels, and vehicles. Unfortunately, due to technological constraints back then, the goal of the engineers became an unrealized dream.
