Prior to the development of circular, corrugated, galvanized steel grain bins, prefabricated, non-corrugated steel bins were used because of cost, portability, rodent resistance and waterproof features, but bin capacity was limited. In the 1920's, corrugated bins, which were larger in size and could support greater loads, were developed and became commercially available. In the 1930's, research programs advanced their use, notably research by F. C. Fenton at Kansas State College of Agriculture and Applied Science and T. E.

The Travel Air Airplane Manufacturing Company served as the incubator in which Wichita Kansas’ present-day status as the world’s “Air Capital” first developed. The firm was among the first viable airplane manufacturers to be established in Wichita (1925). It also was responsible for four aviation legends firmly establishing themselves in Wichita and forming the nexus between Wichita and world aviation: Walter Beech, Olive Ann Mellor (later Olive Ann Beech), Clyde Cessna, and Lloyd Stearman.

When built in 1962, this shovel was the second largest in the world. It was used for the removal of overburden in the surface mining of thin coal seams. In its lifetime, it recovered nine million tons of bituminous coal from depths of 20 to 50 feet for local electric power generation. Standing 160-feet high, weighing 5,500 tons, and moving at speeds up to two-tenths of a mile per hour, the machine stripped about a square mile each year.

This picture of the Big Brutus Mine Shovel does not fully capture its immensity. To create a comparison, the average person would be slightly shorter than the treads, near the bottom.

Working in Bailey Hall on December 7, 1905, Hamilton P. Cady and David F. McFarland discovered significant amounts of helium in a natural gas sample from Dexter, Kansas. Cady and McFarland subsequently analyzed more than 40 other gas samples, showing that helium, previously thought to be rare on Earth but abundant in the Sun, was available in plentiful quantities from the Great Plains of the United States. Helium-filled blimps were vital to the United States in World War II, and helium is still considered a national strategic reserve material.
