The Discovery of Jet Reactions
Greek scholar Hero experiments with reactants and ignition sources, discovering the concept of Jet Reactions. These reactions weren't very powerful, and seen as a waste of energy and resources to pursue it. No one realized the potential of Jet reactions for hundreds of years.

Chinese Use Hero's Principles
The Chinese recognise the potential of Jet Reactions. They begin to create stronger reactions that last longer. The Chinese then housed the reactants responsible for the Jet Reactions at the end of an arrow, and began to use it as a rocket propelled weapon.

Jet Reactions are Used in Machinery
Giovanni Branca begins to use jet exhaust to spin a turbine, which is strong enough to run gears or a belt. Giovanni then develops a stamping mill that runs off of a turbine, driven by jet exhaust. Research and development of the jet engine gains momentum as people begin to see the usefulness of it.

The Three Laws of Motion
Sir Isaac Newton publishes the Three Laws of Motion. These principles, along with the development of jet reactions provide sound theories for jet propulsion. Engines powered by reactants are coming into view.

General Electrics Gets Invovled
General Electrics recognized the potential of jet propulsion. They create their own division of the company devoted to the development of a jet propelled turbine engine. A full fledged race has arisen to build a practical, working prototype.

Further Advancements of the Jet Engine.
The jet engine is adapted for nearly all forms of flight, whether it be for military, shipping, or commercial purposes. The first turbojet to break the sound barrier happens in 1948. In 1955, the first use of the reheat principle is used to make jet engines more efficient.

Jet Propulsion Used in Aircraft
Ernst Heinkel Aircraft uses Hans von Ohian and Max Hahn's patent to create the first gas turbine powered plane, the HE178. It flies so successfully, the Luftwaffe (Nazi Air Force) orders it to be developed to fit the role of a fighter aircraft. The axial flow turbojet is developed, and the ME 262 fighter is born.This is the first turbo jet fighter to enter service.
