Increase in flights - Essay Example DS-3 flew with 21 to 32 passengers (Hoyle and Knowles, 1998). By the time, DS-4 and DS-6 revolutionized the passenger flights and the power associated with them. Boeing and Airbus are two major companies that are providing the world with the passenger airplanes (Armstrong, 1993). The biggest passenger aeroplane is Airbus A-380. It is a double deck plane and made its first flight on 27 April 2005. The seating capacity for this plane is almost 853 for economy class or 525 people in a three-class arrangement. The airbus A-380 can reach the speed of almost 900km/hour or 0.85 mach (Cullingworth, 1997). History Fight history is full of experimentations and theories. The initialization in the field of flying is initiated by the Chinese. Chinese discovered kites round 400BC and people at that time thought that someday man could be able to fly in the air using kites or some other mechanism (Hoyle and Knowles, 1998). After that people, experimented big kites to fly in air but in vain. Chinese used these kites for fun and in their religious ceremonies. These kites are also used in weather testing. In 1480, Leonardo da Vinci proposed many theories about the flight and drew about 100 drawing to support his theories but his flight mechanism never came into reality (Hoyle and Knowles, 1998). In the year of 1783, Joseph and Jacques Montgolfier developed the first hot air balloon. The invention of hot air balloon opened new ways to develop an aircraft. About two centuries ago in 1804 a model of a real time glider is proposed by George Cayley (Armstrong, 1993). The model glider has fixed wings and a movable tail. This concept revolutionized the flight history. In 1853, George Cayley’s invented a glider, which was able to carry man. He named the glider ‘New Flyer’ and it took his footmen across Brompton Dale. In 1874, a piloted aeroplane was made by Felix du Temple, which ran down a ramp (Barrass and Madhavan, 1996). He named it ‘Hop’ and it is un able to take off using its own power. Clement Ader in 1890 created the first piloted aeroplane that is able to take off by using its own power. The name of this aeroplane is Eole. In 1893, first controlled flight was made by Otto Lilienthal (Cullingworth, 1997). He made a true controlled flight and glided up to 230 meters. Wright brothers made a sustained controlled flight in 1903 at Kitty Hawk (Barrass and Madhavan, 1996). Wright brothers made a remarkable contribution in the flight history. Douglas airplanes contributed much in the history of the aeroplanes but when Boeing entered in the market of passenger planes, it made a remarkable contribution in passenger and cargo aeroplanes (Armstrong, 1993). In 1947, Boeing came with new design in aircrafts and presented their first plane and names it Boeing 377 Strato Cruiser. It has four piston driven engines (Hoyle and Knowles, 1998). Modern flights are much more advanced and are able to carry hundreds of passengers and tons of cargo w ith them (Newman and Kenworthy, 1999). Today airplanes have advanced turbo jet engines. Reasons for Increase in Flights Flight is the fastest mean of transport today. The speed of a plane depends on its engine. Today aircraft engines are such made that they can be able to carry tons of loads and maintain a high velocity. The property of an airplane that it can cover large distance in a little span of time makes it a major reason in the increase in flights (Tolley and Turton, 1995). It can save you

Flooding in Ottawa Illinois - Essay Example Finally, by choosing to discuss this hazard, the solutions that come from it will educate public and they will therefore have knowledge in handling such an incident when it occurs. In the last five years, seven disasters were experienced in Illinois. For instance, last summer, more than $300 million was put into operation to aid in management of the aftermath of the flood. Also in June 2008, Midwest floods initiated widespread flood destruction across Illinois owing to insistent heavy rains that caused rivers to spill over their banks. Insured losses to Illinois inhabitants totaled $5.3 million. The Great Midwest Floods of 1993, was one of the biggest floods in U.S. history. The outcome was approximately $273 million uninsured flood destruction and an estimated $15 billion in total damages. The approximate amount of damage cause tolled to around $2.6billion and $60.7 million of them insured losses (Barry, 2007). The probabilistic point of view for flood potential issued by the NWS on March 6, 2014 gives a probabilistic valuation of flood potential using the vocabulary presented below. These viewpoints indicate that the likelihood in percent that slight, modest, or major flooding will take place. Additionally, they provide statistics regarding the possibility a given river stage will be equaled or exceeded during the present forecast period. Property destruction and financial losses are one side of the story. Alternative perspective focuses on the consequence the flooding has had on the surroundings and the modifications it made to the physical land. Flood waters leads to erosion thus changing the shape of the land. This is caused by the chemicals and organic material deposit carried within the floodwaters. Also flood interfere with shipments of essential commodities like foodstuff, chemicals and other products. When canal are flooded and becomes impassable, ship and other marine means of transport
