Why Don't Birds Have Vertical Tails Like Airplanes?

The video discusses how technology is inspired by nature, particularly in aviation. It explains the concept of yaw and sideslip in airplanes, highlighting the role of vertical tails in maintaining stability. Birds, unlike airplanes, do not require vertical tails due to their superior flight capabilities, achieved through constant wing adjustments. The video also touches on the challenges engineers face in replicating these natural abilities in aircraft design.
