These aircraft were larger and stronger and could travel much faster which meant that planes could do more than ever before. The Supermarine Spitfire was developed in the UK and was used by Australian forces who served under the Royal Air Force. It featured a Rolls-Royce merlin engine and could travel at a top speed of 584km/h. It had a wingspan of 11 meters and carried four Browning automatic machine guns. Another famous aircraft was the Avro Lancaster bomber.
Corliss engine changed industry production. Itself the Corliss engine was a marvelous advancement, but it helped powered 800 machines during the centennial exposition. Some machines would be just as ledgendary as their power source. 45 feet hight and a flywheel 30 ft in diameter turned a crankshaft at 36 revolutions per minute and was rated at 1400
Factories became automated. Machines and other improved manufacturing techniques meant that huge amounts of goods could be made at a fraction of the cost. The age of mass production had arrived. In the decade of the 1920s economic output increased by a staggering 50%. Communications revolution – number of telephone doubled/ number of radios increased from 60,000 to 10 million.
Aviation in the Roaring 20’s World War 1 sped the creation of aircraft and aviation, in it’s infancy at the time. Airplanes were first built of wood and canvas, but continual improvement in the aviation industry over the first decade of powered flight led to increasing use of metal in the manufacturing process so by the early 1920's airplanes were more reliable and flew longer ranges while carrying heavier loads. This made ideas of passenger and freight aviation a reality. The ability to travel long distances quickly but with relatively light loads made the earliest freight services mail deliveries. Airmen who returned from World War 1 continued aviation by traveling all over the country visiting small towns and showing off their flying skills and taking paying passengers for rides.
| 1. Question : (TCO B) Three-point estimate: The SuperFlyer Corporation is developing a revolutionary flying disc. The new toy can fly straight over a great distance, which is exciting by itself. However, this disc will also return to the owner in response to their voice! Because this is an advance over anything that this company has done before, estimating the amount and cost of the hi-tech materials are difficult.

Heroes and Heroines By Anna Wright As the 1920s began, the world of aviation was new to the United States. The invention of airplanes was fresh on the American scene, and both men and women found joy in the freedom of flight and the wonder of see their lives far below them. Two particular pilots, Amelia Earhart and Charles Lindbergh, left a lasting impression in aviation, as well as in the hearts of all Americans. Charles Lindbergh, a pilot from a small town in Minnesota, became the first person to make a nonstop solo flight across the Atlantic. Many had previously tried for this accomplishment that came along with a $25,000 reward, but on May 20, 1927, Lindbergh set off on a flight that turned him into a hero (not to mention $25,000 richer).
The expansion would allow for another runway to solve this problem. Capacity would increase dramatically from 480,000 take offs/ landings now, to 605,000 by 2020 and a further increase to 720,000 by 2030. However the greatest cost would be the complete destruction of Greenbelt land and Sipson Village. With the loss of the Village also comes the inevitable loss of the shops, schools and homes. Other arguments for the expansion include jobs and the increase in economy, for example the 3rd runway will boost the economy to a predicted 22 billion.
US Social Issues During World War II William Polk 2012 US Social Issues During World War II William Polk 2012 America’s success in WWII depended heavily on mobilization on the home front. Ultimately, it was this war-time industrial boom that brought the nation out of the Great Depression and made the United States the wealthiest nation in the world after the war ended. During the war years, the U. S. economy expanded rapidly. Each year saw the Gross National Product (GNP) rise by 15 percent or more. Production skyrocketed from 1942-1945 as President Franklin D. Roosevelt ordered the construction of hundreds of thousands of planes and the nation exported massive quantities of supplies, including 2.5 million trucks
At this time people wanted to spend their money instead of save it for hard times. Society’s hourly pay rate nearly double and tripled during this era. War factories transitioned from making war materials to making civilian supplies, which lead to the boost in our economy at the time. Today, effects of the Baby Boom have many factors that come into play that affect our economy. According to National Academy of Social Insurance “social security faces a financial challenge from the impending retirement of the largest generation in American history, the 76 million persons born in the “baby boom” years, from 1946 through 1964.
