TLDR: «through the centuries, the biomechanics that make birds’ maneuverability possible have largely been a mystery.» Until this study offers an explanation.

TLDR: «through the centuries, the biomechanics that make birds’ maneuverability possible have largely been a mystery.» Until this study offers an explanation. They «found that most birds can morph their wings mid-flight to flip back and forth between flying smoothly like a passenger plane and flying acrobatically like a fighter jet.» Ergo, these findings could go into improving aircraft design and aerodynamics of aircraft.
