United States Aircraft Production During World War II
America's manufacturers in World War II were engaged in the greatest military industrial effort in history. Aircraft companies went from building a handful of planes at a time to building them by the thousands on assembly lines. Aircraft manufacturing went from a distant 41st place among American industries to first place in less than five years. In 1939, total aircraft production for the US military was less than 3,000 planes. By the end of the war, America produced 300,000 planes. No war was more industrialized than World War II. In January 1939, President Franklin D. Roosevelt appealed to Congress for $300 million to be spent on procuring aircraft for the Army Air Corps. At the time the Corps had approximately 1,700 aircraft in total. Congress responded and authorized the procurement of 3,251 aircraft. The American aircraft industry was given impetus at the early part of the war by the demand from the British and French for aircraft to supplement their own domestic produ ...

Air Mail Act Of 1925
The Air Mail Act of 1925, also known as the Kelly Act, was a key piece of legislation that intended to free the airmail from total control by the Post Office Department. In short, it allowed the Postmaster General to contract private companies to carry mail. The Act was sponsored by Pennsylvania representative Clyde Kelly, and became legislation in February that year. The act created a bidding period for small airmail routes, setting rates and subsidies contractors would receive for flying mail. The first contracts were awarded to Colonial Air Transport, National Air Transport, Robertson Aircraft Corporation, Western Air Express and Varney Air Lines. Contractors were paid $3.00 per pound of mail for the first 1,000 miles traveled. Due to the surplus aircraft available after the First World War, particularly de Havilland DH-4s, the act bolstered a nascent aviation industry in the United States. By 1927, over 2.5 million miles were traveled by US Airmail Service planes, carr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Airmail
Airmail (or air mail) is a mail transport service branded and sold on the basis of at least one leg of its journey being by air. Airmail items typically arrive more quickly than surface mail, and usually cost more to send. Airmail may be the only option for sending mail to some destinations, such as overseas, if the mail cannot wait the time it would take to arrive by ship, sometimes weeks. The Universal Postal Union adopted comprehensive rules for airmail at its 1929 Postal Union Congress in London. Since the official language of the Universal Postal Union is French, airmail items worldwide are often marked ', literally: "by airplane". For about the first half century of its existence, transportation of mail via aircraft was usually categorized and sold as a separate service (airmail) from surface mail. Today it is often the case that mail service is categorized and sold according to transit time alone, with mode of transport (land, sea, air) being decided on the back end ...

Air Routes Of The United States In 1925
An atmosphere () is a layer of gases that envelop an astronomical object, held in place by the gravity of the object. A planet retains an atmosphere when the gravity is great and the temperature of the atmosphere is low. A stellar atmosphere is the outer region of a star, which includes the layers above the opaque photosphere; stars of low temperature might have outer atmospheres containing compound molecules. The atmosphere of Earth is composed of nitrogen (78%), oxygen (21%), argon (0.9%), carbon dioxide (0.04%) and trace gases. Most organisms use oxygen for respiration; lightning and bacteria perform nitrogen fixation which produces ammonia that is used to make nucleotides and amino acids; plants, algae, and cyanobacteria use carbon dioxide for photosynthesis. The layered composition of the atmosphere minimises the harmful effects of sunlight, ultraviolet radiation, solar wind, and cosmic rays and thus protects the organisms from genetic damage. The current composition of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mass Production
Mass production, also known as mass production, series production, series manufacture, or continuous production, is the production of substantial amounts of standardized products in a constant flow, including and especially on assembly lines. Together with job production and batch production, it is one of the three main production methods. The term ''mass production'' was popularized by a 1926 article in the ''Encyclopædia Britannica'' supplement that was written based on correspondence with Ford Motor Company. ''The New York Times'' used the term in the title of an article that appeared before the publication of the ''Britannica'' article. The idea of mass production is applied to many kinds of products: from fluids and particulates handled in bulk (food, fuel, chemicals and mined minerals), to clothing, textiles, parts and assemblies of parts ( household appliances and automobiles). Some mass production techniques, such as standardized sizes and production lines, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Passenger Airline
An airline is a company that provides air transport services for traveling passengers or freight (cargo). Airlines use aircraft to supply these services and may form partnerships or alliances with other airlines for codeshare agreements, in which they both offer and operate the same flight. Generally, airline companies are recognized with an air operating certificate or license issued by a governmental aviation body. Airlines may be scheduled or charter operators. The first airline was the German airship company DELAG, founded on November 16, 1909. The four oldest non-airship airlines that still exist are the Netherlands' KLM (1919), Colombia's Avianca (1919), Australia's Qantas (1920) and the Russian Aeroflot (1923). Airline ownership has seen a shift from mostly personal ownership until the 1930s to government-ownership of major airlines from the 1940s to 1980s and back to large-scale privatization following the mid-1980s. Since the 1980s, there has been a trend of majo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tony Jannus
Antony Habersack Jannus, more familiarly known as Tony Jannus (July 22, 1889 – October 12, 1916), was an early American pilot whose aerial exploits were widely publicized in aviation's pre-World War I period. He flew the first airplane from which a parachute jump was made, in 1912. Jannus was also the first airline pilot, having pioneered the inaugural flight of the St. Petersburg–Tampa Airboat Line on January 1, 1914, the first scheduled commercial airline flight in the world using heavier-than-air aircraft. The '' Tony Jannus Award'', created to perpetuate his legacy, recognizes outstanding individual achievement in the scheduled commercial aviation industry and is conferred annually by the Tony Jannus Distinguished Aviation Society founded in Tampa, Florida, in 1963. Early years Jannus was born in Washington, D.C., where his father Frankland Jannus was a patent attorney and his great-grandfather, Roger C. Weightman, had previously been mayor from 1824 until 1827.
