Light Heart (balloon)
''Light Heart'' was a balloon constructed by Colonel Thomas Leigh Gatch Jr., USAR (13 September 1925 – disappeared 19 February 1974) for an unsuccessful attempt at the first crossing of the Atlantic Ocean by balloon. Gatch was the son of Vice Admiral Thomas Leigh Gatch (1891–1954) and grandson of photographer Helen Gatch (1862–1942). Balloon design The balloon consisted of a sealed and pressurized envelope suspended from a cluster of ten helium balloons. Each of these was a superpressure balloon (also known as a constant pressure or positive pressure balloon.) In theory, such a balloon can retain a constant altitude over very long-distance flights of several days' duration, since the volume of the envelope remains relatively constant over time. Changes in the pressure of the gas due to heating and cooling are accommodated by mitigating the temperature changes and using an inelastic envelope. The sealed and insulated gondola, which Gatch constructed at home, was designed to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Balloon (aircraft)
In aeronautics, a balloon is an unpowered aerostat, which remains aloft or floats due to its buoyancy. A balloon may be free, moving with the wind, or tethered to a fixed point. It is distinct from an airship, which is a powered aerostat that can propel itself through the air in a controlled manner. Many balloons have a basket, gondola, or capsule suspended beneath the main envelope for carrying people or equipment (including cameras and telescopes, and flight-control mechanisms). Principles A balloon is conceptually the simplest of all flying machines. The balloon is a fabric envelope filled with a gas that is lighter than the surrounding atmosphere. As the entire balloon is less dense than its surroundings, it rises, taking along with it a basket, attached underneath, which carries passengers or payload. Although a balloon has no propulsion system, a degree of directional control is possible through making the balloon rise or sink in altitude to find favorable wind direc ...

Liberia
Liberia (), officially the Republic of Liberia, is a country on the West African coast. It is bordered by Sierra Leone to Liberia–Sierra Leone border, its northwest, Guinea to its north, Ivory Coast to its east, and the Atlantic Ocean to its south and southwest. It has a population of around 5 million and covers an area of . English is the official language, but over 20 indigenous languages are spoken, reflecting the country's ethnic and cultural diversity. The country's capital and largest city is Monrovia. Liberia began in the early 19th century as a project of the American Colonization Society (ACS), which believed black people would face better chances for freedom and prosperity in Africa than in the United States. Between 1822 and the outbreak of the American Civil War in 1861, more than 15,000 freed and free-born black people who faced social and legal oppression in the U.S., along with 3,198 Afro-Caribbeans, relocated to Liberia. Gradually developing an Americo- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Missing Aircraft
This list of missing aircraft includes aircraft that have disappeared and whose locations are unknown. According to ''Annex 13'' of the International Civil Aviation Organization, an aircraft is considered to be missing "when the official search has been terminated and the wreckage has not been located". However, there still remains a "grey area" on how much wreckage needs to be found for a plane to be declared "recovered". This list does not include every aviator, or even every air passenger that has ever gone missing as these are separate categories. In the tables below, each missing aircraft is defined (in the Aircraft column) using one or more identifying features. If the aircraft was known by a custom or personalized name (e.g. ''Pathfinder''), that name is presented first (in italics) followed by the aircraft type (in parentheses). The make of aircraft, although not necessarily a unique identifier, is also provided where appropriate. Aircraft registrations began to be used ...

Individual Balloons (aircraft)
An individual is that which exists as a distinct entity. Individuality (or self-hood) is the state or quality of being an individual; particularly (in the case of humans) of being a person unique from other people and possessing one's own needs or goals, rights and responsibilities. The concept of an individual features in diverse fields, including biology, law, and philosophy. Etymology From the 15th century and earlier (and also today within the fields of statistics and metaphysics) ''individual'' meant " indivisible", typically describing any numerically singular thing, but sometimes meaning "a person". From the 17th century on, ''individual'' has indicated separateness, as in individualism. Law Although individuality and individualism are commonly considered to mature with age/time and experience/wealth, a sane adult human being is usually considered by the state as an "individual person" in law, even if the person denies individual culpability ("I followed instr ...

Aviation Accidents And Incidents In The Atlantic Ocean
Aviation includes the activities surrounding mechanical flight and the aircraft industry. ''Aircraft'' includes fixed-wing and rotary-wing types, morphable wings, wing-less lifting bodies, as well as lighter-than-air craft such as hot air balloons and airships. Aviation began in the 18th century with the development of the hot air balloon, an apparatus capable of atmospheric displacement through buoyancy. Some of the most significant advancements in aviation technology came with the controlled gliding flying of Otto Lilienthal in 1896; then a large step in significance came with the construction of the first powered airplane by the Wright brothers in the early 1900s. Since that time, aviation has been technologically revolutionized by the introduction of the jet which permitted a major form of transport throughout the world. Etymology The word ''aviation'' was coined by the French writer and former naval officer Gabriel La Landelle in 1863. He derived the term from the v ...

List Of People Who Disappeared Mysteriously At Sea
Throughout history, people have mysteriously disappeared at sea, many on voyages aboard floating vessels or traveling via aircraft. The following is a list of known individuals who have mysteriously vanished in open waters, and whose whereabouts remain unknown. In most ocean deaths, bodies are never recovered, but this fact alone does not make their disappearance mysterious. For example, the RMS ''Titanic'' was not a mysterious disappearance. __TOC__ 2nd century BC – 1969 {, class="wikitable sortable plainrowheaders" , - style="text-align:center;" ! width="105" , Date ! width="250" , Person(s) ! width="50" , Age ! width="150" , Missing from ! width="500px" , Circumstances ! width="10px" , , - , data-sort-value="-100-01-01" , 2nd century BC , Eudoxus of Cyzicus , style="text-align:center;" , Unknown , Gulf of Aden , Greek navigator who explored the Arabian Sea for Ptolemy VIII Physcon, who is thought to have perished during a journey to circumnavigate Africa, but ...

Spanish Army
The Spanish Army ( es, Ejército de Tierra, lit=Land Army) is the terrestrial army of the Spanish Armed Forces responsible for land-based military operations. It is one of the oldest active armies — dating back to the late 15th century. The Spanish Army has existed continuously since the reign of King Ferdinand and Queen Isabella (late 15th century). The oldest and largest of the three services, its mission was the defense of Peninsular Spain, the Balearic Islands, the Canary Islands, Melilla, Ceuta and the Spanish islands and rocks off the northern coast of Africa. History During the 16th century, Habsburg Spain saw steady growth in its military power. The Italian Wars (1494–1559) resulted in an ultimate Spanish victory and hegemony in northern Italy by expelling the French. During the war, the Spanish Army transformed its organization and tactics, evolving from a primarily pike and halberd wielding force into the first pike and shot formation of arquebusiers and pi ...
