Transatlantic Aviation
A transatlantic flight is the flight of an aircraft across the Atlantic Ocean from Europe, Africa, South Asia, or the Middle East to North America, Central America, or South America, or ''vice versa''. Such flights have been made by fixed-wing aircraft, airships, balloons and other aircraft. Early aircraft engines did not have the reliability nor the power to lift the required fuel to make a transatlantic flight. There were difficulties navigating over the featureless expanse of water for thousands of miles, and the weather, especially in the North Atlantic, is unpredictable. Since the middle of the 20th century, however, transatlantic flight has become routine, for commercial, military, diplomatic, and other purposes. History The idea of transatlantic flight came about with the advent of the hot air balloon. The balloons of the period were inflated with coal gas, a moderate lifting medium compared to hydrogen or helium, but with enough lift to use the winds that ...

Aircraft
An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), Glider (aircraft), gliders, Powered paragliding, paramotors, and hot air balloons. The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Aircrew, Crewed aircraft are flown by an onboard Aircraft pilot, pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, Powered aircraft#Methods of propulsion, aircraft propulsion, usage and others.

Diplomacy
Diplomacy comprises spoken or written communication by representatives of states (such as leaders and diplomats) intended to influence events in the international system.Ronald Peter Barston, ''Modern diplomacy'', Pearson Education, 2006, p. 1 Diplomacy is the main instrument of foreign policy which represents the broader goals and strategies that guide a state's interactions with the rest of the world. International treaties, agreements, alliances, and other manifestations of international relations are usually the result of diplomatic negotiations and processes. Diplomats may also help to shape a state by advising government officials. Modern diplomatic methods, practices, and principles originated largely from 17th-century European custom. Beginning in the early 20th century, diplomacy became professionalized; the 1961 Vienna Convention on Diplomatic Relations, ratified by most of the world's sovereign states, provides a framework for diplomatic procedures, methods, and ...

Presque Isle, Maine
Presque Isle is the commercial center and largest city in Aroostook County, Maine, United States. The population was 8,797 at the 2020 Census. The city is home to the University of Maine at Presque Isle, Northern Maine Community College, Husson University Presque Isle, Northern Maine Fairgrounds, The Aroostook Centre Mall, and the Presque Isle International Airport. Presque Isle is the headquarters of the Aroostook Band of Micmac, a federally recognized tribe. History The first European settlers were British Loyalists who reached the area in 1819 hoping to obtain land for lumber. Border disputes between the United States and the United Kingdom over the area, however, made it impossible for pioneers to gain title to the land. In response, the government of the neighboring British colony of New Brunswick (now a Canadian province) gave out patents for pioneers to live on the land but not claim ownership or sell it. By 1825, surveyors traveling along the Aroostook River noted ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Double Eagle II
''Double Eagle II'', piloted by Ben Abruzzo, Maxie Anderson and Larry Newman, became the first balloon to cross the Atlantic Ocean when it landed 17 August 1978 in Miserey near Paris, 137 hours 6 minutes after leaving Presque Isle, Maine. It can be regarded as a successful crossing at the point that the ''Double Eagle II'' crossed the Irish coast, on the evening of 16 August, an event that Shannon Airport notified the crew about when it happened. Newman originally intended to hang glide from the balloon to a landing, while Anderson and Abruzzo continued to fly, but the hang-glider had to be dropped as ballast earlier on 16 August. While flying over France, they heard by radio that authorities had closed Le Bourget Airfield, where Charles Lindbergh had landed, for them. The crew declined the offer as they were running out of ballast and it would be too risky (to themselves and anyone below) to pass over the suburbs of Paris. They landed in a field of barley, owned by Roge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Civil War
The American Civil War (April 12, 1861 – May 26, 1865; also known by other names) was a civil war in the United States. It was fought between the Union ("the North") and the Confederacy ("the South"), the latter formed by states that had seceded. The central cause of the war was the dispute over whether slavery would be permitted to expand into the western territories, leading to more slave states, or be prevented from doing so, which was widely believed would place slavery on a course of ultimate extinction. Decades of political controversy over slavery were brought to a head by the victory in the 1860 U.S. presidential election of Abraham Lincoln, who opposed slavery's expansion into the west. An initial seven southern slave states responded to Lincoln's victory by seceding from the United States and, in 1861, forming the Confederacy. The Confederacy seized U.S. forts and other federal assets within their borders. Led by Confederate President Jefferson ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Philadelphia
Philadelphia, often called Philly, is the largest city in the Commonwealth of Pennsylvania, the sixth-largest city in the U.S., the second-largest city in both the Northeast megalopolis and Mid-Atlantic regions after New York City. Since 1854, the city has been coextensive with Philadelphia County, the most populous county in Pennsylvania and the urban core of the Delaware Valley, the nation's seventh-largest and one of world's largest metropolitan regions, with 6.245 million residents . The city's population at the 2020 census was 1,603,797, and over 56 million people live within of Philadelphia. Philadelphia was founded in 1682 by William Penn, an English Quaker. The city served as capital of the Pennsylvania Colony during the British colonial era and went on to play a historic and vital role as the central meeting place for the nation's founding fathers whose plans and actions in Philadelphia ultimately inspired the American Revolution and the nation's inde ...

Henderson, New York
Henderson is a town in Jefferson County, New York, United States. The population was 1,360 at the 2010 census. The town is named after William Henderson, the original European-American land owner. Henderson is in the western part of the county and is southwest of Watertown. The Great Lakes Seaway Trail runs through the town along New York State Route 3 and includes a monument to its founder, William E. Tyson. History This area had long been occupied by the Onondaga people, a nation of the Iroquois Confederacy, a Native American coalition of tribes who controlled most of upstate and western New York around the Great Lakes by the 15th century. Because most nations of the confederacy had allied with the British in the American Revolutionary War, after the defeat of Britain the United States forced the Iroquois to cede most of their land in New York under the terms of the peace treaty. The tribes moved to Canada, where the British offered them land in what is now Ontario. New Y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atlantic
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the "Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8°N. Scientific explorations of the Atl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Wise (balloonist)
John Wise (February 24, 1808 – September 28, 1879) was a pioneer in the field of ballooning. He made over 400 flights during his lifetime and was responsible for several innovations in balloon design. His balloon, ''The Jupiter'' carried 123 letters to make the first official airmail delivery run for the US Post Office in 1859. Early career John Wise was born on February 24, 1808, in Lancaster, Pennsylvania, United States, to William and Mary Trey Weiss who anglicized his surname to Wise. He was the fourth of eight children. He worked as an apprentice cabinetmaker from the time he was 16; after the age of 21 he briefly became a piano maker. A short column and plaque were erected near the corner of East Marion Street and North Lime Street in Lancaster (), by the Lancaster County Historical Society in 1955 stating that Wise "lived most of his life near this spot." He had been interested in ballooning since reading an article in the newspaper when he was 14, and in 1835, at the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jet Stream
Jet streams are fast flowing, narrow, meandering air currents in the atmospheres of some planets, including Earth. On Earth, the main jet streams are located near the altitude of the tropopause and are westerly winds (flowing west to east). Jet streams may start, stop, split into two or more parts, combine into one stream, or flow in various directions including opposite to the direction of the remainder of the jet. Overview The strongest jet streams are the polar jets around the polar vortices, at above sea level, and the higher altitude and somewhat weaker subtropical jets at . The Northern Hemisphere and the Southern Hemisphere each have a polar jet and a subtropical jet. The northern hemisphere polar jet flows over the middle to northern latitudes of North America, Europe, and Asia and their intervening oceans, while the southern hemisphere polar jet mostly circles Antarctica, both all year round. Jet streams are the product of two factors: the atmospheric heating ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helium
Helium (from el, ἥλιος, helios, lit=sun) is a chemical element with the symbol He and atomic number 2. It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas and the first in the noble gas group in the periodic table. Its boiling and melting point are the lowest among all the elements. It is the second lightest and second most abundant element in the observable universe (hydrogen is the lightest and most abundant). It is present at about 24% of the total elemental mass, which is more than 12 times the mass of all the heavier elements combined. Its abundance is similar to this in both the Sun and in Jupiter, due to the very high nuclear binding energy (per nucleon) of helium-4, with respect to the next three elements after helium. This helium-4 binding energy also accounts for why it is a product of both nuclear fusion and radioactive decay. The most common isotope of helium in the universe is helium-4, the vast majority of which was formed during t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
