Wain


A wain is a type of horse-drawn, load-carrying vehicle, used for agricultural purposes quite than transporting people, for example a haywain. It usually has four wheels but the term has now acquired slightly poetical connotation so is not always used with technological correctness. Though, a two-wheeled 'haywain' would be a hay cart, Compare with carriage.
Builders of wains were recognized as Wainwrights, just as the builders of carts were known as Cartwrights. These trades no longer are, but the terms survive as the surnames of children of those practicing these crafts.
The vehicle was the subject of John Constable's 1821 painting The Hay Wain. The painting, which was part of Constable's Gold Medal exhibit to Charles X, depicts a site in Suffolk, near Flat ford on the river Stour.


There are records of early short-distance flights from the 9th to 11th centuries, such as the parachute flight of Armen Firman, the glider flight of Abbas Ibn Firnas, and maybe earlier human-carrying kites from China.
The modern age of aviation began with the first untethered human lighter-than-air flight on November 21, 1783, in a hot air balloon intended by the Montgolfier brothers, and balloon flight became increasingly common over longer and longer distances throughout the 19th century, continuing to the present. On December 17, 1903, the Wright brothers flew the first successful powered, heavier-than-air flight, though their aircraft was not practical to fly for more than a short distance because of control problems. The widespread acceptance of ailerons made aircraft much easier to manage, and only a decade later, at the start of World War I, heavier-than-air powered aircraft had become practical for reconnaissance, artillery spotting, and even attacks against ground positions.
Aircraft began to transport people and cargo as designs grew larger and more dependable. Initially, lighter-than-air airships (also called dirigibles) were supposed to be the most practical means of air transportation of passengers. In the 1930s, however, the Douglas DC-3 became the first airliner that was profitable carrying passengers completely, starting the modern era of passenger airline service. Around the same time, the Hindenburg disaster of 1937 shattered airships' popularity (though there are periodic initiatives to revive their use). By the beginning of World War II, many towns and cities had built airports, and there were numerous capable pilots available. The war brought many innovations to aviation, as well as the first jet aircraft and the first liquid-fueled rockets.
