I never cease to be amazed at the ability of birds, large and small, to fly so gracefully through the sky and perform all kinds of wonderful aerobatics. They are marvelously designed to do so. So marvelous are these designs that Humans have studied them for a basis for our flying machines. There is wisdom greater than human's in evidence there! Just look at this wonderful Great Blue Heron as it makes use of feathers and flaps to glide to a landing in Delta Ponds!

Here are some interesting facts about "What Is Aerodynamics?" in the NASA website:

"Aerodynamics is the way objects move through air. The rules of aerodynamics explain how an airplane is able to fly. Anything that moves through air is affected by aerodynamics, from a rocket blasting off, to a kite flying. Since they are surrounded by air, even cars are affected by aerodynamics."
