During the 300's B.C., the Chinese discovered how to make kites. Later, large kites lifted people into the air.

Explanation
In 1783, two French brothers, the Montgolfiers, made a hot-air balloon. Two other Frenchmen floated over Paris in it. This was the first human flight.

Explanation
Hydrogen is the lightest gas, so it has the greatest lifting power. However, it is easily set on fire, so it can be dangerous. Helium gas is heavier than hydrogen, but it is much safer.

Explanation
The single-rotor helicopter is the most common type of helicopter. It has one main rotor, or set of wings, mounted above its body. It also has a second, smaller rotor on its tail. Twin-rotor helicopters have two main rotors.

Explanation
Most flying machines need wings. Wings produce a force called lift. Lift makes airplanes, helicopters, and other aircraft climb into the air and stay there.

Explanation
Jet planes were developed during World War II (1939-1945). After the war, airliners began to use jet engines

Explanation
Most airplane wings have moving parts that help balance the plane. The ailerons are hinged pieces on the back of the wing. They make the plane bank, or tilt, and turn. Many planes also have flaps that help the plane lift up for takeoff and slow down for landing.

Explanation
On October 14, 1947, Captain Charles E. Yeager of the U.S. Air Force made the first flight that was faster than sound. He flew a rocket-powered airplane called the X-1. In the 1960's, a rocket-powered airplane called the X-15 reached a speed of 4,520 miles (7,274 kilometers) per hour. This was more than six times the speed of sound

Explanation
Blimps were first built in the United States during the early 1900's. People first called them limps because they crumpled up when the gas was let out. The most common type was known as class B, so their name, Blimp, became blimp.

Explanation
Amelia Earhart (1897-1937?) was an American aviator—an airplane pilot. In 1932, she became the first woman to fly alone across the Atlantic Ocean.
Earhart also tried to fly around the world. On May 20, 1937, she took off from Oakland, California, with her navigator, Frederick J. Noonan. On July 1, she took off from New Guinea. Her next stop was supposed to be Howland Island in the middle of the Pacific Ocean. But on the way, she reported that she was running out of fuel. Shortly after that, her plane disappeared. A massive search found no trace of Earhart, Noonan, or their plane. They likely crashed into the ocean and died.
