1909

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:

1909: First woman passenger to fly in the United States

AIAA designated Baddeck, Nova Scotia as a historic site, providing a plaque to commemorate the centennial of the first powered flight in Canada. On February 23, 1909, piloting the “Silver Dart,” J.A. Douglas McCurdy took off from the frozen surface of Bras d’Or Lake at Baddeck Bay, and flew for close to one kilometer before landing safely on ice. The plane had been created by Mabel and Alexander Graham Bell’s Aerial Experiment Association, formed in 1907 to build and fly experimental aircraft.

When opened in 1909, the Queensboro Bridge had the two longest steel cantilever spans in the world - 1,182 feet from Manhattan to Blackwell's Island and 984 feet from Blackwell's Island to Queens. These would remain the world's longest cantilever spans until the completion of the Quebec Bridge in 1917. The Queensboro Bridge has an overall length of 3,724.5 feet. It originally carried two elevated railway lines, two trolley lines, six carriage lanes and two pedestrian walkways. 

When opened in 1909, the 1,470 foot long main span of the Manhattan Bridge was the third longest suspension bridge span in the world, after the nearby Brooklyn and Williamsburg Bridges. The Manhattan Bridge has two 725 foot long suspended side spans for an overall length of 2,920 feet. The bridge deck is supported by 4 main cables of 20.75 inch diameter, each composed of more than 35,000 individual wires. The bridge deck is stiffened by four parallel trusses of 24 foot depth, hinged at the towers.

Prior to 1909 the traditional fishtail bit scraped the rock and quickly dulled in service. The Hughes two-cone bit's revolutionary rolling action crushed hard-rock formations with twin cone-shaped, hardened steel bits, each with 166 cutting edges, revolving on bronze bearings shaped to provide a large surface with reduced friction.

At its completion, the 5.8-mile Gunnison Tunnel under western Colorado's Vernal Mesa was the longest irrigation tunnel in America. It carried water from the Gunnison River to the Uncompahgre Valley to irrigate 146,000 acres of cropland. 

Work on the 30,582-foot tunnel was first performed manually. Adverse geological conditions provided great challenge for this pioneering project. The drilling crews had to deal with clay, sand, shale, and a badly fractured fault zone. 

Bremen Airport was founded in 1909. In 1924, German aviation pioneers Henrich Focke and Georg Wulf founded the Focke-Wulf company on the site. On June 26, 1936, Heinrich Focke’s Fw 61, the world’s first fully operational helicopter, made a successful maiden flight at the airport, piloted by Ewald Rohlfs. Other aircraft developed at the site included the Fw 190 fighter plane, and Fa223 helicopter, both used by the German Luftwaffe in World War Two, as well the VAK 191B, an experimental fighter plane with vertical take-off and landing capabilities, developed in the 1970s.
