Ever since humans first saw birds soar through
the sky, they have wanted to fly. The ancient Greeks and Romans
pictured many of their gods with winged feet, and imagined
mythological winged animals. According to the legend of Daedalus
and Icarus, the father and son escaped prison by attaching
wings made of wax and feathers to their bodies. Unfortunately,
Icarus flew too near the sun, and the heat caused the wax
and feathers to melt. The feathers fell off, and Icarus plummeted
to the sea. Daedalus landed safely in Sicily. |

Legendary characters used the power of mythology
to fly through the heavens. About 100 BC a Greek inventor
known as Hero of Alexandria came up with a new invention that
depended more on the mechanical interaction of heat and water.
He invented a rocket-like device called an aeolipile. It used
steam for propulsion. Hero mounted a sphere on top of a water
kettle. A fire below the kettle turned the water into steam,
and the gas traveled through the pipes to the sphere. Two
L-shaped tubes on opposite sides of the sphere allowed the
gas to escape, and in doing so gave a thrust to the sphere
that caused it to rotate. |

They sounded more like fireworks than rockets
but the Chinese used rockets in battle. |
 |
In 1232 AD the Chinese used rockets against
the Mongols who were besieging the city of Kai-fung-fu. An
arrow with a tube of gunpowder produced an arrow of flying
fire. |
 |
Early Chinese rockets were used in warfare
and celebrations. In fact, the origin of the rocket is shown
simply in these Chinese characters. They stand for both "rocket"
and "fire arrow." |
 |
According to one ancient legend, a Chinese
official named Wan-Hoo attempted a flight to the moon using
a large wicker chair to which were fastened 47 large rockets.
Forty seven assistants, each armed with torches, rushed forward
to light the fuses. In a moment there was a tremendous roar
accompanied by billowing clouds of smoke. When the smoke cleared,
the flying chair and Wan-Hu were gone. |
 |
All through the 13th to the 15th Century
there were reports of many rocket experiments. For example,
Joanes de Fontana of Italy designed a surface-running rocket-powered
torpedo for setting enemy ships on fire. |
 |
In 1650, a Polish artillery expert, Kazimierz
Siemienowicz, published a series of drawings for a staged
rocket. |
