THE WRIGHT BROTHERS
The Wright brothers invented the airplane. Their names were Wilbur (1867-1912) and Orville (1871-1948). Other people had flown through the air on balloons and gliders. But the Wright brothers were the first to fly in an engine-powered airplane. All modern airplanes are based on their work.As children, the Wrights were fascinated by the study of motion. Their mother encouraged them to experiment and learn.
They flew this airplane—called the Flyer—near Kitty Hawk
, North Carolina. With Orville at the controls, the plane flew 120 feet (37 meters) on the first flight. It stayed in the air 12 seconds. The brothers made three more flights that day. The longest, by Wilbur, was 852 feet (260 meters) in length and lasted 59 seconds. For years afterward, most people knew nothing about the Wright brothers’ achievement. A few newspapers reported on the Wrights. But the stories were often inaccurate. Many people at the time doubted that flying machines could even exist. In any case, the Wrights preferred to work quietly, perfecting their airplane and developing flight technique. By 1905, they had created a practical flying machine that could travel dozens of miles. Every modern airplane is based on the Wright brothers’ invention and the principles of flight they discovered.

THE DEVELOPMENT OF THE PLANE
Airplane is an engine-driven machine that can fly through the sky, supported by the flow of air around its wings. Hundreds of thousands of airplanes are used throughout the world. Millions of people depend on aircraft for swift transportation. People and businesses rely on airplanes for the quick delivery of mail and packages. Many industries ship their products by air. Airplanes have many other uses, from helping fight forest fires to carrying emergency aid. In addition, airplanes are a major weapon of war.
Many modern airplanes use jet engines. Jets take in air and burn it with fuel. Some smaller planes, on the other hand, are powered by spinning blades called propellers. Airliners are big planes used by airline companies. Most airliners carry passengers and some cargo. They usually fly 500 to 600 miles (800 to 970 kilometers) per hour.
The biggest airliners have four jet engines. Smaller three-engine and twin-engine airliners make shorter flights. The smallest airliners use propellers.

By Eoin and Graham
On Jan. 1, 1914, the world's first scheduled passenger airline service took off, operating between St. Petersburg and Tampa, Fla. The St. Petersburg-Tampa Airboat Line was a short-lived endeavor — only four months — but it paved the way for today's daily transcontinental flights
Light Bulb
Thomas Edison (1847-1931), was one of the greatest inventors in history. His most famous inventions include electric lighting and the world’s first electric power system. He invented the first practical machine that could record and play back sound. He called this device the phonograph. Edison also made improvements to telegraphs,telephones, and motion pictures.
Edison was an active businessman. He created new companies to manufacture and sell his products. Income from selling his products helped support his research laboratory and the development of more devices. As a result, Edison and other manufacturing pioneers in the late 1800's helped make the United States an industrial world power.
Thomas Edison's middle name was Alva.
Thomas was pulled out of school after twelve weeks. The reason why, was because he annoyed his teachers too much, by asking so many questions.
