  One experiment that he developed was the aeolipile.

  In 1783, the first passengers in the colorful balloon were a sheep, rooster and duck. It climbed to a height of about 6,000 feet and traveled more than 1 mile.

  He designed many different versions of gliders that used the movements of the body to control. A young boy, whose name is not known, was the first to fly one of his gliders.

  One of Lilienthal's Gliders German engineer, Otto Lilienthal, studied aerodynamics and worked to design a glider that would fly. He was the first person to design a glider that could fly a person and was able to fly long distances.

  Samuel Langley was an astronomer, who realized that power was needed to help man fly. He built a model of a plane, which he called an aerodrome, that included a steam-powered engine. In 1891, his model flew for 3/4s of a mile before running out of fuel.

  They designed and used a wind tunnel to test the shapes of the wings and the tails of the gliders. In 1902, with a perfected glider shape, they turned their attention to how to create a propulsion system that would create the thrust needed to fly.
