The **Wright brothers**, **Orville** (August 19, 1871 – January 30, 1948) and **Wilbur** (April 16, 1867 – May 30, 1912), were two Americans who invented and built the world's first successful airplane and making the first controlled, powered and sustained heavier-than-air human flight.http://en.wikipedia.org/wiki/Wright_brothers====== http://www.google.com.hk/imglanding?imgurl=http://www.old-picture.com/wright-brothers/pictures/Wright-Brothers-Airplane-001.jpg&imgrefurl=http://www.old-picture.com/wright-brothers/Wright-Brothers-Airplane-001.htm&h=433&w=600&sz=39&tbnid=F26WCvBW5amVmM:&tbnh=97&tbnw=135&prev=/images%3Fq%3Dwright%2Bbrothers&zoom=1&q=wright+brothers&hl=zh-TW&usg=__PUvaxrdBYqfuArOokVjJ5AWvBVc%3D&sa=X&ei=z434TM36G4mecKmo1LAD&ved=0CD8Q9QEwBQ =The brothers' fundamental breakthrough was their invention of three-axis control, which enabled the pilot to steer the aircraft effectively and to maintain its equilibrium.=

=__When__= In 1900, the Wrights successfully tested their new 50-pound biplane glider with its 17-foot wingspan and wing-warping mechanism at Kitty Hawk, in both unmanned and piloted flights. In fact, it was the first piloted glider. Based upon the results, the Wright Brothers planned to refine the controls and landing gear, and build a bigger glider. http://inventors.about.com/od/wstartinventors/a/TheWrightBrother.htm

Hugo Junkers, a German professor of mechanics introduces the Junkers J4, an all-metal airplane built largely of a relatively lightweight aluminum alloy called duralumin. http://www.greatachievements.org/?id=3728 =__What__=

A **fixed-wing aircraft**, typically called an **aeroplane**, **airplane** or simply **plane**, is an aircraft capable of flight using forward motion that generates lift as the wing moves through the air. Planes include jet engine and propeller driven vehicles propelled forward by thrust, as well as unpowered aircraft (such as gliders), which use thermals, or warm-air pockets to inherit lift. Fixed-wing aircraft are distinct from ornithopters in which lift is generated by flapping wings and rotary-wing aircraft in which wings rotate about a fixed mast. http://en.wikipedia.org/wiki/Fixed-wing_aircraft

It was the first official "engine-powered, controlled fixed wing, heavier-than-air" flight and was completed at Kill Devil Hill, Kitty Hawk in North Carolina.  []
