In appending, the flight behavior of Dragonfly simple , depending aboard the 2 couples of wings knocking constantly . Scientists structural foundation whereby the successful development of the aircraft .
scientists found that bat flight is not By eye , yet by the jaws , pharynx and ears composed of echolocation system, for the issue of ultrasonic bat in flight , but also aware of the obstacles the reflected ultrasound, scientists have accordingly designed a modern radar and radiolocation Ranging apparatus .
dragonfly wings of human invention of the airplane, invented at the cmd 's ultrasonic radar, gravity , and so found by the fall of an apple , ecology is forever quietly reveals to folk the range of human light blind Lights, winking perpetually .
