Hybrid Cars Essay -- Gasoline Electric Hybrid Automobiles

1 Introduction A healthy and prosperous society is based on a healthy and prosperous economy. And during the last century, following the economic growth, the social networks expansion and the geographic dispersion of economic activities, transport became the spinal column of commercial and industrial interaction. The capacity of individuals as well as firms to exchange goods and services became crucial not only for economic purposes but also for better life quality. Unfortunately, the drawback effects of transport have an important impact on the natural and human environments on one hand, and on the growing fuel consumption accompanying the current oil crisis on another hand. Fossil fuel combustion associated to urban transport conditions lead to serious damage to fragile ecosystems and human health as well as contributing to climatic changes and global warming. This leads to the call of the environmental protection agencies and market competition all over the world for significant improvement of fuel economy of all the different classes of vehicles. Meanwhile, studies have confirmed that in recent years, fuel consumption from heavy duty vehicles has grown at a much faster rate then that of passenger cars due to an increase in the demand for transportation of goods [2]. In addition, heavy trucks and buses are normally equipped with highly efficient diesel engines, which limit the opportunities for improvements in fuel economy through studies on the engines efficiency. Consequently, hybrid propulsion systems can be critical solutions to achieve future fuel economy goals for heavy duty vehicles [3]. 2 What is a Hybrid Car.

Badly behaved pupils and parents put teachers off Essay

Suggestions have been raised over the child benefits in United States. For example, Iain Duncan Smith’s suggested that child-related benefits should be limited to two offspring in a family. The fight against the child benefits aren’t justified as they are ill treated. The move should be encouraged as it has helped a good number of the families in the country, in addition limiting the benefit to only a handful (two) children in a family, it doesn’t really play the intended role in the society. Contrary to this, the government should be encouraged to continue with the child benefits program as it has been a gain to a big number of families. Despite the need to have family planning aspects among the people to control the number of children at each family, the child benefit from the government should still remain (Liz, 2014). Child benefit or better still child allowance is a social security payment distributed to parents, children or guardians which highly dependent on the number of children in a family. the child benefit has been effective in helping to support children from less advantaged families which has enables them access essential human needs such a education, food and such. The anti- child benefit campaigns should be shunned as the move is more beneficial to a good number of people and children in the society. Scrubbing the project would land more families especially the poor ones which cannot afford human basic wants. In other words it is the cash expenditure to families with kids not considering their parents income. The advantage amount may vary by the ordinal arrangement of the child, the age of the child, and/or the employment status of the parent. In addition to being of great benefit to the families and children, the benefit helps with extra cost to the families on the extra cost of children. The benefit also includes benefits for women who are pregnant or who have just given birth. The benefits are also helpful to partners whose partners have given birth, people who adopt, tax credits among other benefits. The benefit is essential when one has a responsibility for a child or a young person. In addition to child benefit, there is also the child tax credit. The benefit is also intertwined with the guardians allowances as well as both are meant to help children below the age of 18. The redeployment of income from childless households to families with children, in appreciation of the heavier financial weight incurred by child-rearing (Liz, 2014). Moreover, in order to enjoy the benefits of the child benefit, the benefiting families aren’t required to contribute any national insurance contribution and this in turn comes as gain to the poor families. In addition, the benefit isn’t offered to children who might be under the custody or in prison. In case of child death that was on the child benefit plan, the benefits continue to be given to the family for the next eight weeks. However, despite the benefit behind the child benefit payment, families should be encouraged to practice family planning in order to be able to raise the number of children whom they can comfortably support. The move is however, beneficial in case of calamities such as misfortunes and unemployment’s incase of the parents (Liz, 2014). The child benefit has been beneficial and should be maintained in order to keep boosting the upbringing of the children especially in the financially unstable family. In addition, when the parents loose their jobs they still have the chance to provide for their children, such as food and education. The benefit for the program is numerous and they outweigh the downside of the program. This program is one of the government programs for the grants to the people which have gone miles in assisting less fortunate families financially. A good number countries offer higher benefits levels or supplements for children with disabilities. Family allowances and child benefits are viewed as an instrument that can foster societal cohesion and progress and in turn should be maintained. The benefits also help in strengthening labor force attachments in the country and hence shouldn’t be abolished. Last and not the least, the benefit helps in supplementing the incomes of poor and modest income families with children as a means of reducing or preventing poverty. In conclusion, it’s clear that, the child benefit program is more beneficial to community, and in turn should be maintained. This means the anti-child benefit campaigns should be shunned as the program is of great help to the people. Article (II) Student Behaviour One of the driving forces behind the motivation of teachers in the school is the student behaviours. Badly behaved students are subject to putting off their teachers from the teaching profession. Teachers and school staff understands the changes encountered by students in school and provides them with relevant information and support needed. However, the dedication of the teachers and the staff depends much on the student behaviour and in most cases good behaved students encourages their teachers into the teaching profession. Contrary to this, badly behaved students and teachers are a discouraging factor to the teachers as they put them off from the teaching profession. It is ‘however’ true the student behaviour plays an important role in motivating and maintaining teachers into the profession. The survey is a true reflection of the teachers experience and the parent’s negligence in moulding their children’s behaviour (Jessica, 2014). ‘Badly behaved pupils and parents put teachers off’ was a survey conducted by Guardian Teacher Networks which shows that a good number of teachers have once in awhile considered quitting the profession. Student and parent’s behaviour are essential towards the teacher’s performance in schools. A good number of schools have issues in reference to student behaviours in recent years, which have become a vital problem in modern society. One of factors behind poor student behaviours is collapse of family functions such as divorced family, single parenthood, and children becomes isolated. This in turn leads to bad behaviour among parents and/or students, which de-motivates the teachers. According to the survey, it is clear that, the student or the pupil’s behaviours directly influence the performance of the teachers. Bad behaviour among parents and pupils would negatively influence the teachers and in turn them off from the work. Students who develop behavioural problems from their families are a discouraging aspect to the teachers. It is believed that, pupils/learns important skills and knowledge such as morals and wisdom, which are normally learned from their parents. The survey shows that, the student behaviour is one of the driving factors behind motivated and dedicated teachers (Jessica, 2014). One of the effects of bad student behaviour is that it interferes with individual and other learner’s behaviour. This turns to a challenge for the teacher, as the behaviour challenges day to day running and functioning of schools. In addition, the parents are not helping as much as they would in eradicating negative student and pupils behaviours, hence burdening the work of the teachers purporting them to consider leaving their jobs. Nowadays, the parents have become overprotective to their children. This has not helped at all in taming negative children behaviours and in turn, the burden is left to the teacher to mould the children’s behaviour. For example, an overprotected child expects special treatment at school is in for a frustrating time, which in turn may frustrate the teacher too. The frustration may overwhelm the teacher to a point of making the job dissertation choice. In addition, parents have developed negative expectations for their children which in turn instill negative or unruly behavior in children. From the survey conducted, it’s clearly evident that, â€Å"If unruly behavior is not policed with proper boundaries and a culture of respect for authority at home, teachers cannot effectively implement discipline in the classroom. In addition to negative learner’s behavior, the interference from the government demands of the teacher. 50 % of the interviewed teachers named poor pupil behavior as the main reason behind them leaving the teaching job. The unwanted student behavior influences teachers attitude towards the teaching profession, and if the unruly behavior continues, it may force the teachers to quit the teaching job. Attitude provides a frame for reference for an individual’s conduct and conditions behavior. The creation of unfavorable attitude to the teacher, elicits a reaction of avoidance or aggression towards the job or the learners (Jessica, 2014). In conclusion, it’s clear that, student and parents behavior towards the teachers as well as in the school plays a vital role in molding the teachers. The study reveals that, teacher’s motivation into teaching profession is highly dependent on the children or the learner’s behaviors. The parents are making the scenario worse by failing to support the teachers in the in order to change the learner’s negative behavior into acceptable ones. These demands and the stress accompanying the works force the teacher to quit. The survey, however suggests that â€Å"since its is disruptive children whose behavior is unchecked who miss out the most on their education. That’s why we want to make sure that teachers have more freedom to clamp down on persistently bad behavior without being hampered by bureaucracy, so that teaching time is not lost because of poor behavior,† and in turn prevent a stressing profession to the teachers. This would go miles in im proving both the teachers and students performance in the school. References Liz Jones. You don’t pay for my cats – so why should I pay for your kids?

Fleur Adcock: Analysis of Instead of an Interview Essay

‘Instead of an Interview’ by Fleur Adcock, is a poem essentially about the divided sense of identity she has inherited: from both family (or historical) emigrant experience and personal deportation. In the poem, the issue is complicated, as Adcock explores the loss and alienation that emerges from the choice of long-term separation from family. It begins with descriptive visual imagery, where Adcock attempts to familiarise herself with the childhood images of â€Å"The hills†, â€Å"water, the clean air†, and â€Å"a river or two†, â€Å"certain bays†, and â€Å"those various and incredible hills†. The description almost seems like a ramble, which evokes a fresh and exciting experience. Although we learn later on in this poem that she addresses England as her â€Å"home†, this stanza largely bears feelings of nostalgia. The â€Å"ah† in the last line of the stanza re-emphasises her expression of relief, relaxation and comfort, after her first visit back to New Zealand after 13 years. Through this poem, Adcock offers â€Å"snapshots† of her family’s past, and the struggles of family, marriage, and life. In the second stanza, we see Fleur warming up to the familiarity of New Zealand – the â€Å"streets I could follow blind†, and other â€Å"familiar settings†. There seems to be a sense of distress, as Fleur is engaging in parts of her past that she has tried to forget about. Coming back to her birthplace appears to be more overwhelming, than comforting. It seems like she had gone away because she hadn’t like it enough to stay. Whether good or bad, â€Å"the dreams (she’d) not bothered to remember† kept creeping back automatically as she passed â€Å"familiar settings†. She further relates this attachment with the atmosphere of the country: â€Å"ingrained; ingrown; incestuous: like the country. The elaborated vowel sounds enhance the warmth of the stanza, drawing the reader closer to Adock’s personal feelings. The semicolons serve as caesuras, creating dramatic pauses for emphasis. The slightly grotesque terms – â€Å"ingrained†, â€Å"ingrown†, â€Å"incestuous† – are used to emphasise the vividness of her hometown memories, as if they were carved into her thoughts. The three adjectives and the caesuras have a rapid flow, which then shifts to a lingering rhythm with â€Å"like the country†, composed of three words. This sudden change in rhythm brings about a grand atmosphere or aura, especially ue to the end-stopped line, since this breaks the flow and changes to a new stanza. The use of â€Å"country† enhances this importance – her memories and country complement one another, emphasising the size and enormity of these â€Å"ingrained†, â€Å"ingrown†, and â€Å"incestuous† memories. Another significant and extremely personal connection mentioned in this stanza is, â€Å"my Thorndon† – Thorndon being the capital city of New Zealand. The personal pronoun â€Å"my† emphasises a sense of belonging and possession, as though she wants to point out that this country is a significant part of her childhood. In the third stanza, Fleur is genuine to mention all the wonderful things ‘another city’ in New Zealand offered to her: â€Å"a lover†, â€Å"quite enough friends†, in terms of relationships. Her use of caesuras is evident once again in the third line: â€Å"bookshops; galleries; fish in the sea†. She is heightening the reader’s interest with her clever use of punctuation, once again emphasising the different and essential memories of her country. The reader is able to identify from this line Fleur’s many areas of interest. She seems to enjoy the company of nature – natural imagery is abundant in this particular stanza. The â€Å"gardens†, â€Å"fish in the sea†, â€Å"lemons and passionfruit† signify her love for nature. It is evident that these authentic memories are destroyed due to urbanisation; as she mentions in the earlier stanza – â€Å"half my Thorndon smashed for the motorway†. The trees and gardens were ruined over the years and replaced by synthetic and unnatural materials. Hence, her sense of possession has strengthened, with whatever piece of nature and memory that remains. ‘Instead of an Interview’ exposes Adcock’s sense of an identity split between New Zealand and Britain. This alternating change in culture evidently created confusion with Adcock identifying herself. Adcock explained to her niece, â€Å"home is London; and England, Ireland, Europe. â€Å"Perhaps she is entirely attached (maybe temporarily) to the British culture, since she has practically lived there her whole adult and professional life. After visiting her birth town, all the childhood memories came flooding in; perhaps she resisted them because she is still so confused about where she really belongs. The idea of ‘home’ being a â€Å"loaded word† re-emphasises her befuddled state of being. Adding to that, the poem ends with a question ark: â€Å"have I made myself for the first time an exile? † This use of punctuation leaves the reader puzzled, with plenty of questions, because the speaker herself is unsure about her identity. For the first time, Fleur feels she has made herself an â€Å"exile†, which is the state of being expelled from one’s native country. This is a serious dilemma and seems as though she wrote this poem in a slightly sentimental hangover from having visited New Zealand after 13 years. What is misleading is that the poem comes across as Adcock’s way of saying she does not like to talk or be interviewed but rather to show her emotions through her poems.

Biography of Henry Clinton, British General

Biography of Henry Clinton, British General Henry Clinton (April 16, 1730–Dec. 23, 1795) was the Commander of the British North American forces during the American War for Independence. Fast Facts: Henry Clinton Known For: Commander of the British North American forces during the American War for IndependenceBorn: About 1730 in Newfoundland, Canada or Stourton Parva, England.Parents: Admiral George Clinton (1686–1761) and Ann Carle (1696–1767).Died: December 23, 1795 in GibraltarEducation: In New York colony and possibly studied under Samuel SeaburyPublished Works: The American Rebellion: Sir Henry Clintons Narrative of His Campaigns, 1775–1782Spouse: Harriet Carter (m. 1767–1772)Children: Frederick (1767–1774), Augusta Clinton Dawkins (1768–1852), William Henry (1769–1846), Henry (1771–1829), and Harriet (1772) Early Life Henry Clinton was likely born in 1730 to Admiral George Clinton (1686–1761), at the time the Governor of Newfoundland and Labrador, and his wife Ann Carle (1696–1767). References are that available post his birth date as 1730 or 1738; English peerage records state the date as April 16, 1730, but list his birth location as Newfoundland and George Clinton did not arrive until 1731. Henry Clinton had at least two sisters who survived to adulthood,  Lucy Mary Clinton Roddam, 1729–1750, and Mary Clinton Willes (1742–1813), and Lucy Mary was born in Stourton Parva, Lincolnshire, England.   Little more than that is known about his childhood: what there is comes primarily from 19th-century brief biographical records and the letters and documents left by Clinton himself. When George Clinton was appointed governor of New York in 1743, the family moved there and it is assumed that Henry was educated in the colony and may have studied under Samuel Seabury (1729–1796), the first American Episcopal bishop. Early Military Career Beginning his military career with the local militia in 1745, Clinton obtained a captains commission the following year and served in the garrison at the recently captured fortress of Louisbourg on Cape Breton Island.  Three years later, he traveled back to England with hopes to secure another commission in the British Army. Purchasing a commission as a captain in the Coldstream Guards in 1751, Clinton proved to be a gifted officer. Swiftly moving through the ranks by buying higher commissions, Clinton also benefited from family connections to the Dukes of Newcastle. In 1756, this ambition, along with assistance from his father, saw him gain an appointment to serve as aide-de-camp to Sir John Ligonier. Seven Years War By 1758, Clinton had reached the rank of lieutenant colonel in the 1st Foot Guards (Grenadier Guards). Ordered to Germany during the Seven Years War, he saw action at the Battles of Villinghausen (1761) and  Wilhelmsthal (1762).  Distinguishing himself, Clinton was promoted to colonel effective June 24, 1762, and appointed an aide-de-camp to the armys commander, Duke Ferdinand of Brunswick. While serving in Ferdinands camp, he developed a number of acquaintances including future adversaries Charles Lee and William Alexander (Lord Stirling). Later that summer both Ferdinand and Clinton were wounded during the defeat at Nauheim. Recovering, he returned to Britain following the capture of Cassel that November.   With the end of the war in 1763, Clinton found himself head of his family as his father had died two years earlier. Remaining in the army, he endeavored to resolve his fathers affairs- which included collecting an unpaid salary, selling land in the colonies, and clearing a large number of debts. In 1766, Clinton received command of the 12th Regiment of Foot.   In 1767 he married Harriet Carter, the daughter of a wealthy landowner. Settling in Surrey, the couple would have five children (Frederick (1767–1774), Augusta Clinton Dawkins (1768–1852), William Henry (1769–1846), Henry (1771–1829), and Harriet (1772).  On May 25, 1772, Clinton was promoted to major general, and two months later he used family influence to gain a seat in Parliament. These advancements were tempered in August when Harriet died a week after giving birth to their fifth child. After she died, Henrys in-laws moved into his house to raise the children. He apparently acquired a mistress at a later point in his life and had a family with her, but their existence is merely mentioned in Clintons surviving correspondence. The American Revolution Begins Crushed by the loss of wife, Clinton failed to take his seat in Parliament and instead traveled to the Balkans to study the Russian army in 1774. While there, he also viewed several of the battlefields from the Russo-Turkish War (1768–1774). Returning from the trip, he took his seat in September 1774. With the American Revolution looming in 1775, Clinton was dispatched to Boston aboard HMS Cerberus with Major Generals William Howe and John Burgoyne to provide assistance to Lieutenant General Thomas Gage. Arriving in May, he learned that fighting had begun and that Boston had fallen under siege.  Assessing the situation, Clinton brusquely suggested manning Dorchester Heights but was refused by Gage. Though this request was denied, Gage did make plans for occupying other high ground outside of the city, including Bunker Hill. Failure in the South On June 17, 1775, Clinton took part in the bloody British victory at the Battle of Bunker Hill. Initially tasked with providing reserves to Howe, he later crossed to Charlestown and worked to rally the dispirited British troops. In October, Howe replaced Gage as commander of British troops in America and Clinton was appointed as his second-in-command with the temporary rank of lieutenant general. The following spring, Howe dispatched Clinton south to assess military opportunities in the Carolinas. While he was away, American troops emplaced guns on Dorchester Heights in Boston, which compelled Howe to evacuate the city. After some delays, Clinton met a fleet under Commodore Sir Peter Parker, and the two resolved to attack Charleston, South Carolina. Landing Clintons troops on Long Island, near Charleston, Parker hoped the infantry could aid in defeating the coastal defenses while he attacked from the sea. Moving forward on June 28, 1776, Clintons men were unable to render assistance as they were halted by swamps and deep channels. Parkers naval attack was repulsed with heavy casualties and both he and Clinton withdrew. Sailing north, they joined Howes main army for the assault on New York. Crossing to Long Island from the camp on Staten Island, Clinton surveyed the American positions in the area and devised the British plans for the upcoming battle. Success in New York Utilizing Clintons ideas, which called for a strike through the Guan Heights via Jamaica Pass, Howe flanked the Americans and led the army to victory at the Battle of Long Island in August 1776. For his contributions, he was formally promoted to lieutenant general and made a Knight of the Order of Bath. As tensions between Howe and Clinton increased due to the latters constant criticism, the former dispatched his subordinate with 6,000 men to capture Newport, Rhode Island in December 1776. Accomplishing this, Clinton requested leave and returned to England in spring 1777. While in London, he lobbied to command a force that would attack south from Canada that summer but was denied in favor of Burgoyne. Returning to New York in June 1777, Clinton was left in command of the city while Howe sailed south to capture Philadelphia. Possessing a garrison of only 7,000 men, Clinton feared attack from General George Washington while Howe was away. This situation was made worse by calls for help from Burgoynes army, which was advancing south from Lake Champlain. Unable to move north in force, Clinton promised to take action to aid Burgoyne. In October he successfully attacked American positions in the Hudson Highlands, capturing Forts Clinton and Montgomery, but was unable to prevent Burgoynes eventual surrender at Saratoga. The British defeat led to the Treaty of Alliance (1778) which saw France enter the war in support of the Americans. On March 21, 1778, Clinton replaced Howe as commander-in-chief after the latter resigned in protest over British war policy. In Command Taking command at Philadelphia, with Major General Lord Charles Cornwallis as his second-in-command, Clinton was immediately weakened by the need to detach 5,000 men for service in the Caribbean against the French. Deciding to abandon Philadelphia to focus on holding New York, Clinton led the army into New Jersey in June. Conducting a strategic retreat, he fought a large battle with Washington at Monmouth on June 28 which resulted in a draw. Safely reaching New York, Clinton began drawing up plans for shifting the focus of the war to the South where he believed Loyalist support would be greater. Dispatching a force late that year, his men succeeded in capturing Savannah, Georgia. After waiting for much of 1779 for reinforcements, Clinton was finally able to move against Charleston in early 1780. Sailing south with 8,700 men and fleet led by Vice Admiral Mariot Arbuthnot, Clinton laid siege to the city on March 29. After a prolonged struggle, the city fell on May 12 and over 5,000 Americans were captured. Though he wished to lead the Southern Campaign in person, Clinton was forced to turn over command to Cornwallis after learning of a French fleet approaching New York. Returning to the city, Clinton attempted to oversee Cornwallis campaign from afar. Rivals who did not care for each other, Clinton and Cornwallis relationship continued to be strained. As time passed, Cornwallis began to operate with increasing independence from his far-away superior. Hemmed in by Washingtons army, Clinton limited his activities to defending New York and launching nuisance raids in the region. In 1781, with Cornwallis under siege at Yorktown, Clinton attempted to organize a relief force. Unfortunately, by the time he departed, Cornwallis had already surrendered to Washington. As a result of Cornwallis defeat, Clinton was replaced by Sir Guy Carleton in March 1782. Death Officially turning command over to Carleton in May, Clinton was made the scapegoat for the British defeat in America. Returning to England, he wrote his memoirs in an attempt to cleanse his reputation and resumed his seat in Parliament until 1784. Re-elected to Parliament in 1790, with assistance from Newcastle, Clinton was promoted to general three years later. The following year he was appointed Governor of Gibraltar, but died in Gibraltar on Dec. 23, 1795, before taking over the post.

Korean War MiG-15 Communist Jet Fighter

Korean War MiG-15 Communist Jet Fighter In the immediate wake of World War II, the Soviet Union captured a wealth of German jet engine and aeronautical research. Utilizing this, they produced their first practical jet fighter, the MiG-9, in early 1946. While capable, this aircraft lacked the top speed of the standard American jets of the day, such as the P-80 Shooting Star. Though MiG-9 was operational, Russian designers continued to have issues perfecting the German HeS-011 axial-flow jet engine. As a result, airframe designs produced by Artem Mikoyan and Mikhail Gurevichs design bureau began to outpace the ability to produce engines to power them. While the Soviets struggled with developing jet engines, the British had created advanced centrifugal flow engines. In 1946, Soviet aviation minister Mikhail Khrunichev and aircraft designer Alexander Yakovlev approached Premier Joseph Stalin with the suggestion of buying several British jet engines. Though not believing that the British would part with such advanced technology, Stalin gave them permission to contact London. Much to their surprise, the new Labour government of Clement Atlee, which was friendlier towards the Soviets, agreed to the sale of several Rolls-Royce Nene engines along with a licensing agreement for overseas production. Bringing the engines to the Soviet Union, engine designer Vladimir Klimov immediately began reverse-engineering the design. The result was the Klimov RD-45. With the engine issue effectively resolved, the Council of Ministers issued decree #493-192 on April 15, 1947, calling for two prototypes for a new jet fighter. Design time was limited as the decree called for test flights in December. Due to the limited time allowed, designers at MiG elected to use the MiG-9 as a starting point. Modifying the aircraft to include swept wings and a redesigned tail, they soon produced the I-310. Possessing a clean appearance, the I-310 was capable of 650 mph and defeated the Lavochkin La-168 in trials. Re-designated the MiG-15, the first production aircraft flew December 31, 1948. Entering service in 1949, it was given the NATO reporting name Fagot. Principally intended for intercepting American bombers, such as the B-29 Superfortress, the MiG-15 was equipped with two 23 mm cannon and one 37 mm cannon. MiG-15 Operational History The first upgrade to the aircraft came in 1950, with the arrival of the MiG-15bis. While the aircraft contained numerous minor improvements, it also possessed the new Klimov VK-1 engine and external hardpoints for rockets and bombs. Widely exported, the Soviet Union provided the new aircraft to the Peoples Republic of China. First seeing combat at the end of the Chinese Civil War, the MiG-15 was flown by Soviet pilots from the 50th IAD. The aircraft scored its first kill on April 28, 1950, when one downed a Nationalist Chinese P-38 Lightning. With the outbreak of the Korean War in June 1950, the North Koreans began operations flying a variety of piston-engine fighters. These were soon swept from the sky by American jets and B-29 formations began a systematic aerial campaign against the North Koreans. With the Chinese entry into the conflict, the MiG-15 began to appear in the skies over Korea. Quickly proving superior to straight-wing American jets such as the F-80 and F-84 Thunderjet, the MiG-15 temporarily gave the Chinese the advantage in the air and ultimately forced United Nations forces to halt daylight bombing. MiG Alley The MiG-15s arrival compelled the US Air Force to begin deploying the new F-86 Sabre to Korea. Arriving on the scene, the Sabre restored balance to the air war. In comparison, the F-86 could out dive and out turn the MiG-15, but was inferior in rate of climb, ceiling, and acceleration. Though the Sabre was a more stable gun platform, the MiG-15s all-cannon armament was more effective than the American aircrafts six .50 cal. machine guns. In addition, the MiG benefited from the rugged construction typical of Russian aircraft which made it difficult to bring down. The most famous engagements involving the MiG-15 and F-86 occurred over northwestern North Korea in an area known a MiG Alley. In this area, Sabres and MiGs frequently dueled, making it the birthplace of jet vs. jet aerial combat. Throughout the conflict, many MiG-15s were covertly flown by experienced Soviet pilots. When encountering American opposition, these pilots often were evenly matched. As many of the American pilots were veterans of World War II, they tended to have the upper hand when facing MiGs flown by North Korean or Chinese pilots. Later Years Eager to inspect the MiG-15, the United States offered a bounty of $100,000 to any enemy pilot who defected with an aircraft. This offer was taken up by Lieutenant No Kum-Sok who defected on November 21, 1953. At the end of the war, the US Air Force claimed a kill ratio of around 10 to 1 for MiG-Sabre battles. Recent research has challenged this and suggested that the ratio was much lower. In the years after Korea, the MiG-15 equipped many of the Soviet Unions Warsaw Pact allies as well as numerous other countries around the world. Several MiG-15s flew with the Egyptian Air Force during the 1956 Suez Crisis, though their pilots were routinely beaten by the Israelis. The MiG-15 also saw extended service with the Peoples Republic of China under the designation J-2. These Chinese MiGs frequently skirmished with Republic of China aircraft around the Straits of Taiwan during the 1950s. Largely replaced in Soviet service by the MiG-17, the MiG-15 remained in many countries arsenals into the 1970s.
