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.

 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.

Mulholland Drive is one of the best-known addresses in the Los Angeles area. It follows the crest of the Santa Monica Mountains, northwest of the city. Movie stars live there, and their homes command sweeping views of the San Fernando Valley, Beverly Hills, Santa Monica, and Los Angeles itself. Yet the drive’s namesake, William Mulholland, was neither a Hollywood mogul nor a wealthy landowner. He was the city’s water superintendent from 1886 to 1928.

New York City’s General Post Office unfurls its grand white facade along two full blocks between Thirty-first and Thirty-third Streets on Eighth Avenue. It’s open around the clock all year long (as midnight draws nigh on April 15, representatives of the Maalox and Excedrin concerns pass out free samples to harried taxpayers in the tall marble hall), so at any hour a passer-by may drop in and poke into the alcoves where displays of mail pouches and old photographs and engravings tell the history of the New York postal service.

500 CPS Synchronous Rotary Gap transmitter at Brant Rock, Ma. Ca: 1906.

On 24 December 1906, the first radio broadcast for entertainment and music was transmitted from Brant Rock, Massachusetts to the general public. This pioneering broadcast was achieved after years of development work by Reginald Aubrey Fessenden (1866-1932) who built a complete system of wireless transmission and reception using amplitude modulation (AM) of continuous electromagnetic waves. This technology was a revolutionary departure from transmission of dots and dashes widespread at the time.

First Operational Use Of Wireless Telegraphy

The first use of wireless telegraphy in the field occurred during the Anglo-Boer War (1899-1902). The British Army experimented with Marconi's system and the British Navy successfully used it for communication among naval vessels in Delagoa Bay, prompting further development of Marconi's wireless telegraph system for practical uses. The Anglo-Boer War of 1899-1902 will be remembered as the last of the gentleman's wars, the war that marked the end of the Victorian era.

In 1902 and 1903 he requested some patents for the system. With the Telekine, Torres-Quevedo laid down modern wireless remote-control operation principles. Torres Quevedo also made some important contributions to aeronautics, a field in which he carried out important research on dirigible balloons.

Stevens Pass Railroad Tunnels & Switchback System
Society: ASCE Main Category: Civil Sub Category: Rail Transportation Era: 1900-1909 DateCreated: 1900 Stevens Pass State: WA Zip: 98826 Country: USA Website: Creator: Stevens, John F.

In the years following the Civil War, the land west of the Mississippi River was being settled and the Pacific Northwest explored. There remained, however, a large portion of Montana, Idaho, and Washington that contained enormous quantities of timber and minerals, but was not accessible by rail. By far the most grueling stretch was the Stevens Pass area in the Cascade Mountains.

Hudson and Manhattan Railroad Tunnel

A transportation tunnel under the Hudson River connecting Manhattan and New Jersey was first considered in the 1860s, fueled by New York City's rapidly growing congestion and the inadequacy of existing ferry service to population centers across the river. DeWitt Clinton Haskin, an engineer formerly with the Union Pacific Railroad, started the project in 1874 and subsequently endured an extended lawsuit, several failures of the tunnel wall, and an exhaustion of funds before quitting in 1887 with only 1,600 feet completed.
