Observe four different animals that fly and tell how they fly. edit
Flying fish are members of the family Exocoetidae, and use their remarkable abilities to shake off predators. Whilst underwater, flying fish make good use of their super-streamlined shape to gain speeds of up to 60 kilometres per hour, placing them in the top 10 fastest fish. They then propel themselves upwards to break the surface, where they use their tails to skim along the water before fully taking to the air.
Their impressive pectoral fins help them reach heights of 1.2 metres and distances of up to 200 metres. But that’s not all – when the fish lose height and approach the water, they can again beat their tails to travel across the surface and prolong their flight to 400m
Japanese flying squid
Unusually, the squid from the family Ommastrephidae uses jet propulsion to drive itself into the air, by drawing water underneath its mantle – its outer layer – and releasing it in a high-powered blast. Its fins and tentacles then double as wings, creating aerodynamic lift, which allows it to travel for three seconds and cover distances of 30 metres.
This fine-tuned technique, in which the squid carefully adjusts its posture to prolong its flight, has prompted scientists to declare that the squid it not simply gliding, but truly flying.
Most impressively, this unassuming squid could give Usain Bolt a run for his money, reaching speeds of 11.2 metres per second, compared to Bolt who averaged 10.5 metres per second in his 2009 100 metre world record sprint. Now that really is the stuff of nightmares.
bee does not flap its wings up and down, but back and forth. This movement creates mini hurricanes, which in turn generates areas of low pressure above the wing and, voila, the bumblebee can fly!
Backwards, sideways, hovering, somersaults – this tiny bird can move in ways that others can only dream of, and it does it by inverting its wings to produce lift on the upstroke as well as the downstroke.
This technique is actually more similar to that of an insect than the hummingbird’s avian kin, but the hummingbird’s skeleton does not allow it to rotate its wings at the base like an insect, so instead it twists its wrists.
While the flying squirrel can only glide for short distances, bats are true fliers. A bat’s wing resembles a modified human hand — imagine the skin between your fingers larger, thinner and stretched. This flexible skin membrane that extends between each long finger bone and many movable joints make bats agile fliers.

Know where the Bible speaks of an angel flying. edit
Revelation 14:6 Then I saw another angel flying in midair, and he had the eternal gospel to proclaim to those who live on the earth—to every nation, tribe, language and people.
Know who were the first successful, motorized, airplane pilots. edit
The Wright Brothers (Orville & Wilbur) on Dec. 17, 1903.
The Wright brothers – Orville (August 19, 1871 – January 30, 1948) and Wilbur (April 16, 1867 – May 30, 1912) – were two American aviation pioneers generally credited with inventing, building, and flying the world's first successful motor-operated airplane. They made the first controlled, sustained flight of a powered, heavier-than-air aircraft with the Wright Flyer on December 17, 1903, 4 mi (6 km) south of Kitty Hawk, North Carolina. The brothers were also the first to invent aircraft controls that made fixed-wing powered flight possible.
In 1904–1905, the Wright brothers developed their flying machine to make longer-running and more aerodynamic flights with the Wright Flyer II, followed by the first truly practical fixed-wing aircraft, the Wright Flyer III. The brothers' breakthrough was their creation of a three-axis control system, which enabled the pilot to steer the aircraft effectively and to maintain its equilibrium. This method remains standard on fixed-wing aircraft of all kinds. From the beginning of their aeronautical work, Wilbur and Orville focused on developing a reliable method of pilot control as the key to solving "the flying problem". This approach differed significantly from other experimenters of the time who put more emphasis on developing powerful engines. Using a small home-built wind tunnel, the Wrights also collected more accurate data than any before, enabling them to design more efficient wings and propellers. Their first U.S. patent did not claim invention of a flying machine, but rather a system of aerodynamic control that manipulated a flying machine's surfaces.
The brothers gained the mechanical skills essential to their success by working for years in their Dayton, Ohio-based shop with printing presses, bicycles, motors, and other machinery. Their work with bicycles, in particular, influenced their belief that an unstable vehicle such as a flying machine could be controlled and balanced with practice. From 1900 until their first powered flights in late 1903, they conducted extensive glider tests that also developed their skills as pilots. Their shop employee Charles Taylor became an important part of the team, building their first airplane engine in close collaboration with the brothers.
The Wright brothers' status as inventors of the airplane has been subject to counter-claims by various parties. Much controversy persists over the many competing claims of early aviators. Edward Roach, historian for the Dayton Aviation Heritage National Historical Park, argues that they were excellent self-taught engineers who could run a small company, but they did not have the business skills or temperament to dominate the growing aviation industry.
