Montgolfier Brothers
They tested the France air balloon through 8-km flight across Paris. The Montgoldfier Brothers discovered that the balloon made of linen bags with five-heated air had enough lift to carry two people. This is important,because they need to know how long it goes,and how many people it can carry -
Sir George Cayley
He studied animal flight an designed a monoplane glider to carry humans. He flew it across a balley at his home at Brompton Hall,near 1853 Sacar borough. It's important so they know it can be for humans,and that they can use it to fly in the air. -
Otto Lilienthal
He launched a glider whose flight could be controlled by the shifting his weight. He was the first Heavier-than-air pilot. it's important because people need to know how to control the glider in the air that he designed. it's also important because people can also have fun with it or use it for something important. -
The Wright Brothers
They made the first successful powered flight. They decided to test their aircraft at Kitty Hawk North Carolina. The first aircraft lasted 72 s,and travelled a distance of 36.5m. It's important,because people can travel from far away easily. -
Chuck Yeager
He broke the sound barrier by flying faster than the speed of sound in a rocket-powered X-1 plane. He continued to test new aircraft and set a new airspeed record of more than twice the speed of sound in 1952. It's important because they needed to test and find out the speed. -
Avro Arrow
He designed the most advanced airplane of its time in the 1950s.Its test speed was Mach 1.98 times the speed of sound. The plane all had additional parts. it's important because it helps them discover more advance technologies.
