The Wright Brothers' Flight
1903It all started at Kittyhawk in North Carolina. The Wright Brothers had been testing different gliders and kites in the late 1800's, and in 1900 decidedto try their hand at Airplane Building.Their first glider, made weighing only 50 pounds was called the "Unmannedkite It was propelled by having a 150 foot tower drop a counter weight andpushing it off of the side of a hill. This was the start of their plans. In 1901,the Wright's increased the gliders size. Now it had a 22 foot wingspan, andwas a total of 7 feet deep. They took it out a little past Kittyhawk, to a placewhere the hills were somewhat better suited for launching a glider. With thisone, they wanted to try free flight before taking it near a hill.

Unfortunately,the larger version wouldn't lift for free flight, and they were forced to movethe glider to a hill and launch it there.The 1901 glider hadn't lifted because of a mistake in their calculations. Theywere off in the amount of space that they needed on the wings to get the proper lift. They spent the year of 1902 redesigning their glider from the pasttwo to something that they could sit in, control, and have it fly on it's own. The new glider was bigger, had a somewhat different look, and a powerplant.

Then in 1903, history was made.On December 17, 1903, The Wright Brothers, with Orville at the controls,made their history making flight in the first self propelled, heavier than air machine called the Wright B Flyer. It took them 45 feet to get off the groundthen 12 seconds later and 120 feet away, the plane touched back to Earth.We had flown!The Wrights continued to modify their plane until they got to the longest flightthey had ever had of 1 hour and 17 minutes. Today planes can travel over 10hours at a time, and 120 feet is the length of their wingspan, and it can takenearly 3/4's of a mile to get off the ground.
