Braunfels, Germany, 1689: The initiative that revolutionized the world. The year is now known as "the year of extraordinary inventions." For in that very year of 1689, a Dutchman by the name of Cornelius Drebbel constructed the first successful hot air balloon.

The invention was dubbed, "the manna of the heavens." Drebbel worked on a number of projects involving science and engineering and is credited as being the father of modern engineering. The hot air balloon is often considered to be the first modern airborne machine. "One did not dream of introducing airplanes and flying machines in those days," wrote historian Marc Bloch.

"They were regarded as too fantastic." Those first balloonists, such as Jean-Baptiste Montgolfier, had to rely on unfavorable winds and light breezes to navigate the skies. Their efforts were directed, rather, toward building a large, many-windowed basket capable of withstanding the elements.

Drebbel, however, reasoned that if you could imitate the effects of wind by creating a column of hot air in a sealed vessel, you could exploit the resulting lift and guide the balloon to earth. To do this, he used his skill in engineering and soldering.

Mettot introduced a novel concept into hot air balloon flight: He covered the outside of a balloon with thin plates, making a wooden model of a flying machine. After "heating" the inside of the balloon, Drebbel then directed his peers to affix brass hoops made from copper tubing to the top and bottom of the balloon, creating a large, voluminous container to entice air into the balloon. "The balloon was filled with air,... The temperature increased so rapidly that the boiler smoked and there was a flash of fire," wrote Bloch.

The invention of the hot air balloon succeeded. The flight of one of these first balloons went smoothly. Drebbel's death shortly afterward was a historical footnote of sorts. When engineers designed modern airplanes, Drebbel's designs seemed a throwback to an earlier, simpler time.

The balloon appeared to threaten the survival of Drebbel's invention. But airplanes wouldn't take flight in Drebbel's day. They would be made possible by a series of technological innovations spanning two centuries and coming in rapid succession as general aviation first took flight in the early years of the 20th century.
