The Rumely Companies, which operated in La Porte, Indiana, from 1853 to 1931, produced a variety of equipment including threshers and steam engines, which helped to change the nature of American and world agriculture. The revolutionary OilPull Tractor, which was introduced in 1910, used a unique carburetion system developed by John Secor, the Company's Chief Engineer. The OilPull tractor efficiently converted a low cost petroleum product to mechanical power, greatly reducing the need for animal and steam power on American farms. Dr.

This site, originally the home of the Eclipse-Pioneer Division of the Bendix Aviation Corporation, has produced navigational instruments and engine components since 1938. Providing instruments that flew with Lindbergh across the Atlantic, and Admiral Byrd in the cold of Antarctica; from guiding American pilots in times of peace and war, to putting men on the moon, the “Bendix Invisible Crew” has been a leader in innovation and technology in the world of aviation and space exploration.

Established in 1946 to provide a comprehensive test and evaluation site for tactical missiles, Point Mugu has been instrumental in the development, test, evaluation and in-service support of systems including Regulus, Sparrow, Phoenix, Bullpup, Harpoon, SLAM, Tomahawk, Standard, and Rolling Airframe Missile. The first missile launch from an operational submarine was also accomplished at Pt. Mugu.

College Park Airport was founded in 1909 when the Wright Brothers came here to train the first military officers to fly in the givernment's first airplane. The airport is the oldest continuously operated airport in the world, and has come to be known as "The Field of Firsts" due to it being the location of a great number of groundbreaking achievements, such as:

The 1905 Wright Flyer III, built by Wilbur (1867-1912) and Orville (1871-1948) Wright, was the world's first airplane capable of sustained, maneuverable flight. Similar in design to their celebrated first airplane, this machine featured a stronger structure, a larger engine turning new "bent-end" propellers, and greater control-surface area for improved safety and maneuverability.

The idea of creating a canal linking the Mediterranean Sea to the Red Sea is a very old one that dates back about 4000 years to the ancient Egyptians. They thought of linking the two seas by using the River Nile and its branches. It was this very old desire that led to the digging of the present Suez Canal.

This highly diverse facility has pioneered the development of solar energy applications worldwide. The Solar Energy and Energy Conversion Laboratory (SEECL) was unique in developing practical solar energy devices based on established principles of thermodynamics, heat transfer, and fluid mechanics long before solar energy was considered a serious energy alternative.

This mechanism allowed the manual closing of a well, saved lives and prevented surface oil accumulation at drilling sites, quickly becoming an industry standard. In the early days of oilfield operations, there was no way to control the underground pressures encountered during drilling. When an oil or gas reservoir was tapped, wells were allowed to "blow out" until pressure was reduced sufficiently to allow capping. Many inventors attempted to develop a device to control such blowouts. In 1922, oil wildcatter James Smither Abercrombie (1891-1975) and machinist Harry S.
