 On 19 August, the AIAA Historic Aerospace Sites Committee dedicated Kitty Hawk, NC, as a historic aerospace site, following a decades-long negotiation with the U.S Park Service. A historic marker was unveiled at a 0930 hrs ceremony as part of the First Flight Society’s National Aviation Day at Kitty Hawk. At this site on 17 December 1903, Orville and Wilbur Wright achieved the first sustained, controlled heavier-than-air flight of an aircraft, opening a new era of transportation throughout the world.

When opened in 1903, the 1,600 foot long main span of the Williamsburg Bridge was the world's longest suspension span, surpassing the nearby Brooklyn Bridge by only 4.5 feet. The Williamsburg Bridge remained the world's longest suspension bridge span for 21 years until the opening of the Bear Mountain Bridge in 1924. The Williamsburg Bridge has two unsuspended side spans of 596.5 feet, each supported from below by trussed towers, giving the bridge an overall length of 2,793 feet. The four main suspension cables are 18.75 inches in diameter and each composed of over 10,000 wires.

Ingalls Building

The 16-story Ingalls Building, still in use today, was the world's first reinforced concrete skyscraper. Its success led to the acceptance of high-rise concrete construction in the United States.

Melville E. Ingalls, for whom the building is named, spent two years convincing city officials to issue a building permit. Skepticism was high, because the existing height record for a concrete building was only six stories.

Goldfields Water Supply

Originally known as the Coolgardie Goldfields Water Supply Scheme, the Goldfields Water Supply, Western Australia, has exceptional and unique cultural significance for Australia.  Western Australia's first Premier, the dynamic and visionary Sir John Forrest, recognized the need for this extraordinary project to support the young and burgeoning gold mining industry in the dry interior of the state.  In 1896 he directed C Y O'Connor, the colony's first Engineer-in-Chief, to find a permanent solution to the water supply problem in the area, which lacked any permanent surface water supplies and

Detroit Edison District Heating System

The concept of heating a number of buildings in the core area of a city from a single heating plant was introduced into the United States by Birdsill Holly at Lockport, New York, in 1877. The gain in thermal efficiency of a single large steam plant over a series of small isolated boilers led to widespread commercial installation of district heating. Organized by the Detroit Edison Company, the Central Heating Company began service here in 1903, supplying twelve customers with steam piped from the Edison Company's Willis Avenue Plant. Today's greatly enlarged system continues in operation.

Chain of Rocks Water Purification Plant

Clarifying the turbid waters of the Mississippi River for use as drinking water was a formidable challenge. The Chain of Rocks Water Purification Plant provided the first application of a system of flocculation, sedimentation, and rapid sand filtration for water purification.

The system played a major role in reducing the impact of St. Louis' typhoid and cholera epidemic of 1903 that claimed 287 lives. Continued improvements to the plant reduced that number to 91 by 1914. It is estimated that 1,900 lives were likely saved between 1903 and 1915 due to the filtration system.

This, the first Curtis vertical turbine built, was constructed by the General Electric Co. for the Newport & Fall River Street Railway Co. It operated in the Newport, R.I., generating station until June 1927. It was transferred to the Harding Street Station of the Indianapolis Power & Light Co. for display and later moved to the company's E.W. Stout Station.
