Gas Balloon
A gas balloon is a balloon that rises and floats in the air because it is filled with a gas lighter than air (such as helium or hydrogen). When not in flight, it is tethered to prevent it from flying away and is sealed at the bottom to prevent the escape of gas. A gas balloon may also be called a '' Charlière'' for its inventor, the Frenchman Jacques Charles. Today, familiar gas balloons include large blimps and small latex party balloons. For nearly 200 years, well into the 20th century, manned balloon flight utilized gas balloons before hot-air balloons became dominant. Without power, heat or fuel, untethered flights of gas balloons depended on the skill of the pilot. Gas balloons have greater lift for a given volume, so they do not need to be so large, and they can stay up for much longer than hot air balloons. History The first gas balloon made its flight in August 1783. Designed by professor Jacques Charles and Les Frères Robert, it carried no passengers or cargo. On ...

Béthune ( ; archaic and ''Bethwyn'' historically in English) is a city in northern France, sub-prefecture of the Pas-de-Calais department. Geography Béthune is located in the former province of Artois. It is situated south-east of Calais, west of Lille, and north of Paris. Landmarks Béthune is a town rich in architectural heritage and history. It has, among other features, a large paved square with shops, cafés, and a (133 steps) belfry standing in the center from the top of which the Belgian border can be seen. The chime of the belfry is composed of thirty-six bells. A belfry (French:''"beffroi"'') has stood on the site since 1346.

Felix Baumgartner
Felix Baumgartner (; born 20 April 1969) is an Austrian skydiver, daredevil and BASE jumper. He is widely known for jumping to Earth from a helium balloon from the stratosphere on 14 October 2012 and landing in New Mexico, United States, as part of the Red Bull Stratos project. Doing so, he set world records for skydiving an estimated , reaching an estimated top speed of , or Mach 1.25. He became the first person to break the sound barrier relative to the surface without vehicular power on his descent. He broke skydiving records for exit altitude, vertical freefall distance without a drogue parachute, and vertical speed without a drogue. Though he still holds the two latter records, the first was broken two years later, when on 24 October 2014, Alan Eustace jumped from 135,890 feet—or, with a drogue. Baumgartner is also renowned for the particularly dangerous nature of the stunts he has performed during his career. He spent time in the Austrian military where he practiced ...

Albuquerque International Balloon Fiesta
The Albuquerque International Balloon Fiesta is a yearly hot air balloon festival that takes place in Albuquerque, New Mexico, during early October. The Balloon Fiesta is a nine-day event occurring in the first full week of October, and has over 500 hot air balloons each year far from its humble beginnings of merely 13 balloons in 1972. The event is the largest balloon festival in the world, followed by the Grand Est Mondial Air in France. History The Balloon Fiesta began in 1972 as the highlight of a 50th birthday celebration for 770 KOB Radio. Radio station manager Dick McKee asked Sid Cutter, owner of Cutter Flying Service and the first person to own a hot air balloon in New Mexico, if KOB could use his new hot-air balloon as part of the festivities. The two began discussing ballooning, along with conversation and help from Oscar Kratz, and McKee asked what the largest gathering of hot air balloons to date had been. 19 balloons in England, Cutter replied.

Airship
An airship or dirigible balloon is a type of aerostat or lighter-than-air aircraft that can navigate through the air under its own power. Aerostats gain their lift from a lifting gas that is less dense than the surrounding air. In early dirigibles, the lifting gas used was hydrogen, due to its high lifting capacity and ready availability. Helium gas has almost the same lifting capacity and is not flammable, unlike hydrogen, but is rare and relatively expensive. Significant amounts were first discovered in the United States and for a while helium was only available for airships in that country. Most airships built since the 1960s have used helium, though some have used hot air.A few airships after World War II used hydrogen. The first British airship to use helium was the ''Chitty Bang Bang'' of 1967. The envelope of an airship may form the gasbag, or it may contain a number of gas-filled cells. An airship also has engines, crew, and optionally also payload accommodation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jean-Pierre Blanchard
Jean-Pierre rançoisBlanchard (4 July 1753 – 7 March 1809) was a French inventor, best known as a pioneer of gas balloon flight, who distinguished himself in the conquest of the air in a balloon, in particular the first crossing of the English Channel, on 7 January 1785. Biography 1784 - Flights in Paris Blanchard made his first successful balloon flight in Paris on 2 March 1784, in a hydrogen gas balloon launched from the Champ de Mars. The first successful manned balloon flight had taken place on 21 November 1783, when Pilâtre de Rozier and the Marquis d'Arlandes took off at Palace of Versailles in a free-flying hot air balloon constructed by the Montgolfier brothers. The first manned hydrogen balloon flight had taken place on 1 December 1783, when Professor Jacques Charles and Nicolas-Louis Robert launched '' La Charlière'' from the Jardin des Tuileries in Paris. Blanchard's flight nearly ended in disaster, when one spectator (Dupont de Chambon, a contemporary of Napole ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thaddeus Lowe
Thaddeus Sobieski Constantine Lowe (August 20, 1832 – January 16, 1913), also known as Professor T. S. C. Lowe, was an American Civil War aeronaut, scientist and inventor, mostly self-educated in the fields of chemistry, meteorology, and aeronautics, and the father of military aerial reconnaissance in the United States. By the late 1850s he was well known for his advanced theories in the meteorological sciences as well as his balloon building. Among his aspirations were plans for a transatlantic flight. Lowe's scientific endeavors were cut short by the onset of the American Civil War, for which he offered his services performing aerial reconnaissance on the Confederate troops for the Union Army. In July 1861 Lowe was appointed Chief Aeronaut of the Union Army Balloon Corps by President Abraham Lincoln. Though his work was generally successful, it was not fully appreciated by all members of the military, and disputes over his operations and pay scale forced him to resign in ...
