Progressively Wild Bill Hickok’s eyesight became worse‚ so he decided to become a traveling gambler instead of being in Buffalo Bill Cody’s Wild West Show. A few years later on March 5‚ 1876‚ Wild Bill Hickok married Agnes Thatcher Lake. After only a couple months of marriage‚ Wild Bill Hickok left Agnes to “seek his fortune in the goldfields of South Dakota”( Wild Bill Hickok)

of times their size. There are many factors that contribute to the hummingbirds ’ ability to fly so easily through the air. A hummingbird ’s wings are shaped so that they are slightly rounded on the top. "Their wings flaps 15-80 times per second‚ depending on the type of species they are. The Giant Hummingbird ’s wings beat 8-10 beats per second‚ the wings of medium size hummingbirds beat 20-25 beats per second and the smallest beat 70 beats per second."< http://en.wikipedia.org/wiki/Hummingbirds>

weight. Thrust is the force that propels the object forward. For every action there is an equal but opposite reaction‚ therefore the force opposite of thrust is drag. The main forms of drag are pressure‚ and friction drag. Aerodynamics‚ engines‚ wings and flaps are the main factors that affect an aircraft’s ability to fly. Weight is a force that is always directed towards the earth‚ vertically‚ through the planes center of gravity. An airplanes mass would be the weight of all its parts‚ plus

Another extremely important design factor is adding dihedral and maybe even polyhedral to the glider’s wings. This allows the plane to “naturally” stabilize itself. Dihedral is the upward angle of the wings on a plane and polyhedral is upward angle further down the wings. I’m going to put dihedral and polyhedral however‚ together they both will add up to an angle of 8 degrees which I believe would be an overall good angle. The reason

for their ever-growing and everlasting love for aviation. throughout 1901‚ 1902‚ they made numerous flight attempts with biplane gliders‚ with minor adjustments (i.e. adding a tail‚ curving wings to make dihedral angle‚ etc.) But it wasn’t until they funded for a wind tunnel did they figure out that if the wings itself thickened in the middle to form a “teardrop” form that sustained

extended. Aircraft of all types and sizes are flying with winglets -- from single-seat hang gliders and ultralights to global jumbo jets. Some aircraft are designed and manufactured with sleek upturned winglets that blend smoothly into the outer wing sections. Add-on winglets are also custom made for many types of aircraft. The concept of winglets originated with a British aerodynamicist in the late 1800s‚ but the idea remained on the drawing board until rekindled in the early 1970s by Dr. Richard
