|---|---|
| Silk Bag | Contains hot air. |
| Basket | Carries passengers and cargo. |
| Fire | Heats the air. |
The Montgolfier brothers, Joseph Michel and Jacques Etienne, invented the first hot air balloon. They used smoke from a fire to fill a silk bag with hot air, which, when attached to a basket, made the balloon lighter than air. In 1783, the first passengers—a sheep, a rooster, and a duck—ascended to 6,000 feet and traveled over a mile. This successful flight paved the way for manned balloon flights, with Jean-Francois Pilatre de Rozier and Francois Laurent making history on November 21, 1783.
2.6. George Cayley’s Gliders: Pioneering Fixed-Wing Flight
George Cayley dedicated his efforts to finding a means for human flight. He designed numerous gliders controlled by body movements. An unnamed young boy became the first person to fly one of his gliders. Over five decades, Cayley refined his designs, modifying wing shapes to improve airflow, adding a tail for stability, and experimenting with biplane designs for enhanced strength. He also recognized the necessity of power for sustained flight.
Cayley’s treatise, On Ariel Navigation, detailed the concept of a fixed-wing aircraft with a propulsion system and a tail for control, outlining the fundamental principles for enabling human flight.
These early efforts, spanning from kites to gliders, represent critical milestones in the quest for human flight, setting the stage for the advancements of the 19th and 20th centuries.
