A crucial step in the evolution of modern plant agriculture was the development of low-cost, energy-efficient greenhouse structures that provide optimum growing conditions year-round. In 1964, Professor William J. Roberts developed the first air-inflated double-layer polyethylene greenhouse covering system at Cook College, Rutgers University.

Agricultural Aviation Began In 1921 When C. R. Neillie Got A Military Plane To Dust Catalpa Trees Near Troy, OH. In 1922 B. R. Coad And C. E. Wollman Began Research At Tallulah, LA To Control Boll Weevils In Cotton. They Developed Equipment Using Venturi Induction, Ram Air Pressure And Hopper Agitation. G. B. Post And Wollman Made The First Commercial Dust Applications In Macon, Ga In 1924. In 1925, 18 Aircraft Treated 60,000 Acres Of Cotton Across The South. In 1928, Delta Air Service Was Organized.

H. John Eastman introduces controlled directional drilling in 1929 and was awarded a patent the following year.
The technique became widely adopted after an oil strike in Conroe, Texas, caught fire in January 1933. The well exploded, creating a 600-foot deep crater, and the oil burned for months. Although the fire was eventually put out, oil continued to flow into the “lake.” The only way to manage this was to drill another well to relieve the pressure.

This Federal Laboratory has played a pivotal role in creating our modern air traffic control system. Established as the National Aviation Facilities Experimental Center in 1958, the Technical Center’s research and engineering achievements, and its direct support to airports and FAA air traffic control facilities have led to the highest level of safety in air transportation.

Known as the birthplace of Naval Aviation, North Island was the site of the first successful seaplane flight and the first amphibious flight in the U.S., both made by Glenn Curtiss. The first Naval pilot, Lt. T.G. Ellyson, was trained here at the Curtiss Aviation Camp. A flight school established here by Ellyson trained the next Naval aviators as well as the Navy’s first aviation maintenance personnel. North Island was also the site of the first night flight, and the home of the first aircraft carrier, the USS Langley.

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.

The Purdue University Airport was the first collegiate owned airport in the United States. It hosted Amelia Earhart for her final adventure, was the training ground for test pilots such a Jimmy Johnson and Ivan Kincheloe, balloonist Malcolm Ross, and astronaut Neil Armstrong. Purdue University Airport and its people and programs pushed aviation’s evolution to new heights and helped expand the frontiers of flight. During WWII, hundreds of U.S. Army and Navy members were trained at the airport.
