Edwin Albert Link
Edwin Albert Link (July 26, 1904 – September 7, 1981) was an American inventor, entrepreneur and pioneer in aviation, underwater archaeology, and submersibles. He invented the flight simulator, which was called the "Blue Box" or "Link Trainer". It was commercialized in 1929, starting a now multibillion-dollar industry. In total, he obtained more than 27 patents for aeronautics, navigation and oceanographic equipment. Early life Edwin Link was born in Huntington, Indiana, in 1904, the son of Edwin A. Link, Sr., and Katherine (Martin) Link. In 1910, he moved with his family to Binghamton, New York. Aviation Aviator He took his first flying lesson in 1920. In 1927, he obtained the first Cessna airplane ever delivered and eked out a living by barnstorming, charter flying and giving lessons. As a young man, Edwin Link used apparatus from his father's automatic piano and organ factory (of the Link Piano and Organ Company) to produce an advertising airplane. A punched roll and ...

Barnstorming
Barnstorming was a form of entertainment in which stunt pilots performed tricks individually or in groups that were called flying circuses. Devised to "impress people with the skill of pilots and the sturdiness of planes," it became popular in the United States during the Roaring Twenties. Barnstormers were pilots who flew throughout the country to sell airplane rides and perform stunts. Charles Lindbergh first began flying as a barnstormer. Barnstorming was the first major form of civil aviation in the history of aviation. History Background The Wright brothers and Glenn Curtiss had early flying exhibition teams, with solo flyers like Lincoln Beachey and Didier Masson also popular before World War I, but barnstorming did not become a formal phenomenon until the 1920s. The first barnstormer, taught to fly by Curtiss in 1909, was one Charles Foster Willard, who is also credited as the first to be shot down in an airplane when an annoyed farmer broke his propeller firing ...

Underwater Diving
Underwater diving, as a human activity, is the practice of descending below the water's surface to interact with the environment. It is also often referred to as diving, an ambiguous term with several possible meanings, depending on context. Immersion in water and exposure to high ambient pressure have physiological effects that limit the depths and duration possible in ambient pressure diving. Humans are not physiologically and anatomically well-adapted to the environmental conditions of diving, and various equipment has been developed to extend the depth and duration of human dives, and allow different types of work to be done. In ambient pressure diving, the diver is directly exposed to the pressure of the surrounding water. The ambient pressure diver may dive on breath-hold (freediving) or use breathing apparatus for scuba diving or surface-supplied diving, and the saturation diving technique reduces the risk of decompression sickness (DCS) after long-duration deep dives ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Army Air Corps
The United States Army Air Corps (USAAC) was the aerial warfare service component of the United States Army between 1926 and 1941. After World War I, as early aviation became an increasingly important part of modern warfare, a philosophical rift developed between more traditional ground-based army personnel and those who felt that aircraft were being underutilized and that air operations were being stifled for political reasons unrelated to their effectiveness. The USAAC was renamed from the earlier United States Army Air Service on 2 July 1926, and was part of the larger United States Army. The Air Corps became the United States Army Air Forces (USAAF) on 20 June 1941, giving it greater autonomy from the Army's middle-level command structure. During World War II, although not an administrative echelon, the Air Corps (AC) remained as one of the combat arms of the Army until 1947, when it was legally abolished by legislation establishing the Department of the Air Force. The Air ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amusement Park
An amusement park is a park that features various attractions, such as rides and games, as well as other events for entertainment purposes. A theme park is a type of amusement park that bases its structures and attractions around a central theme, often featuring multiple areas with different themes. Unlike temporary and mobile funfairs and carnivals, amusement parks are stationary and built for long-lasting operation. They are more elaborate than city parks and playgrounds, usually providing attractions that cater to a variety of age groups. While amusement parks often contain themed areas, theme parks place a heavier focus with more intricately-designed themes that revolve around a particular subject or group of subjects. Amusement parks evolved from European fairs, pleasure gardens, and large picnic areas, which were created for people's recreation. World's fairs and other types of international expositions also influenced the emergence of the amusement park industry ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Link Trainer (WCAM)
The term Link Trainer, also known as the "Blue box" and "Pilot Trainer" is commonly used to refer to a series of flight simulators produced between the early 1930s and early 1950s by Link Aviation Devices, founded and headed by Ed Link, based on technology he pioneered in 1929 at his family's business in Binghamton, New York. During World War II, they were used as a key pilot training aid by almost every combatant nation. The original Link Trainer was created in 1929 out of the need for a safe way to teach new pilots how to fly by instruments. Ed Link used his knowledge of pumps, valves and bellows gained at his father's Link Piano and Organ Company to create a flight simulator that responded to the pilot's controls and gave an accurate reading on the included instruments. More than 500,000 US pilots were trained on Link simulators, as were pilots of nations as diverse as Australia, Canada, Germany, New Zealand, United Kingdom, Israel, Japan, Pakistan, and the USSR.
