Flight 19 was the designation of a group of five General Motors TBM Avenger torpedo bombers that disappeared over the Bermuda Triangle on December 5, 1945, after losing contact during a United States Navy overwater navigation training flight from Naval Air Station Fort Lauderdale, Florida. All 14 airmen on the flight were lost, as were all 13 crew members of a Martin PBM Mariner flying boat that subsequently launched from Naval Air Station Banana River to search for Flight 19. A report by Navy investigators concluded that flight leader Lt. Charles C. Taylor mistook small islands offshore for the Florida Keys after his compasses stopped working, resulting in the flight heading over open sea and away from land. The report was later amended by the Navy to read "cause unknown" to avoid blaming Taylor for the loss of five aircraft and 14 men. The report attributed the loss of the PBM aircraft to an explosion in mid-air while searching for the flight. Navigation training fl ...

Grumman TBF Avenger
The Grumman TBF Avenger (designated TBM for aircraft manufactured by General Motors) is an American World War II-era torpedo bomber developed initially for the United States Navy and Marine Corps, and eventually used by several air and naval aviation services around the world. The Avenger entered U.S. service in 1942, and first saw action during the Battle of Midway. Despite the loss of five of the six Avengers on its combat debut, it survived in service to become the most effective and widely-used torpedo bomber of World War II, sharing credit for sinking the super-battleships and (the only ships of that type sunk exclusively by American aircraft while under way) and being credited for sinking 30 submarines. Greatly modified after the war, it remained in use until the 1960s.Wheeler 1992, p. 53. Design and development The Douglas TBD Devastator, the U.S. Navy's main torpedo bomber introduced in 1935, was obsolescent by 1939. Bids were accepted from several companies, but Grum ...

Ensign (rank)
Ensign (; Late Middle English, from Old French (), from Latin (plural)) is a junior rank of a commissioned officer in the armed forces of some countries, normally in the infantry or navy. As the junior officer in an infantry regiment was traditionally the carrier of the ensign flag, the rank acquired the name. This rank has generally been replaced in army ranks by second lieutenant. Ensigns were generally the lowest-ranking commissioned officer, except where the rank of subaltern existed. In contrast, the Arab rank of ensign, لواء, ''liwa''', derives from the command of units with an ensign, not the carrier of such a unit's ensign, and is today the equivalent of a major general. In Thomas Venn's 1672 ''Military and Maritime Discipline in Three Books'', the duties of ensigns are to include not only carrying the color but assisting the captain and lieutenant of a company and in their absence, have their authority. "Ensign" is ''enseigne'' in French, and ''chorąży'' in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dogmatic
Dogma is a belief or set of beliefs that is accepted by the members of a group without being questioned or doubted. It may be in the form of an official system of principles or doctrines of a religion, such as Roman Catholicism, Judaism, Islam or Protestantism, as well as the positions of a philosopher or of a philosophical school such as positivism, postmodernism, egalitarianism, and dark enlightenment. It may also be found in political belief-systems, such as Marxism, communism, capitalism, progressivism, liberalism, conservatism, and fascism. In the pejorative sense, dogma refers to enforced decisions, such as those of aggressive political interests or authorities. More generally, it is applied to some strong belief which its adherents are not willing to discuss rationally. This attitude is named as a dogmatic one, or as dogmatism; and is often used to refer to matters related to religion, but is not limited to theistic attitudes alone and is often used with respect to p ...

Consolidated PBY Catalina
The Consolidated PBY Catalina is a flying boat and amphibious aircraft that was produced in the 1930s and 1940s. In Canadian service it was known as the Canso. It was one of the most widely used seaplanes of World War II. Catalinas served with every branch of the United States Armed Forces and in the air forces and navies of many other nations. The last military PBYs served until the 1980s. As of 2021, 86 years after its first flight, the aircraft continues to fly as a waterbomber (or airtanker) in aerial firefighting operations in some parts of the world. None remain in military service. Design and development Background The PBY was originally designed to be a patrol bomber, an aircraft with a long operational range intended to locate and attack enemy transport ships at sea in order to disrupt enemy supply lines. With a mind to a potential conflict in the Pacific Ocean, where troops would require resupply over great distances, the U.S. Navy in the 1930s invested millions ...

Naval Air Station Banana River
Patrick Space Force Base is a United States Space Force installation located between Satellite Beach and Cocoa Beach, in Brevard County, Florida, United States. It is named in honor of Major General Mason Patrick, USAAC. It is home to Space Launch Delta 45 (SLD 45), known as the 45th Space Wing (45 SW) when it was part of the Air Force. In addition to its "host wing" responsibilities at Patrick SFB, the 45 SW controls and operates Cape Canaveral Space Force Station (CCSFS) and the Eastern Range. It was originally opened and operated from 1940 to 1947 as Naval Air Station Banana River, a U.S. Navy airfield. It was then deactivated as a naval installation in 1947 and placed in caretaker status until it was transferred to the Air Force in late 1948. Additional tenant activities at Patrick SFB include the 920th Rescue Wing, the Air Force Technical Applications Center, and the Defense Equal Opportunity Management Institute (DEOMI). Total employment is 10,400. There are 13, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Water Landing
In aviation, a water landing is, in the broadest sense, an aircraft landing on a body of water. Seaplanes, such as floatplanes and flying boats, land on water as a normal operation. Ditching is a controlled emergency landing on the water surface in an aircraft not designed for the purpose, a very rare occurrence. Controlled flight into the surface and uncontrolled flight ending in a body of water (including a runway excursion into water) are generally not considered water landings or ditching. Aircraft water landings By design Seaplanes, flying boats, and amphibious aircraft are designed to take off and alight on water. Alighting can be supported by a hull-shaped fuselage and/or pontoons. The availability of a long effective runway was historically important on lifting size restrictions on aircraft, and their freedom from constructed strips remains useful for transportation to lakes and other remote areas. The ability to loiter on water is also important for marine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History (U
History (derived ) is the systematic study and the documentation of the human activity. The time period of event before the invention of writing systems is considered prehistory. "History" is an umbrella term comprising past events as well as the memory, discovery, collection, organization, presentation, and interpretation of these events. Historians seek knowledge of the past using historical sources such as written documents, oral accounts, art and material artifacts, and ecological markers. History is not complete and still has debatable mysteries. History is also an academic discipline which uses narrative to describe, examine, question, and analyze past events, and investigate their patterns of cause and effect. Historians often debate which narrative best explains an event, as well as the significance of different causes and effects. Historians also debate the nature of history as an end in itself, as well as its usefulness to give perspective on the problems of the p ...

Secondary Surveillance Radar
Secondary surveillance radar (SSR)''Secondary Surveillance Radar'', Stevens M.C. Artech House, is a radar system used in air traffic control (ATC), that unlike primary radar systems that measure the bearing and distance of targets using the detected reflections of radio signals, relies on targets equipped with a radar transponder, that reply to each interrogation signal by transmitting encoded data such as an identity code, the aircraft's altitude and further information depending on its chosen mode. SSR is based on the military identification friend or foe (IFF) technology originally developed during World War II, therefore the two systems are still compatible. Monopulse secondary surveillance radar (MSSR), Mode S, TCAS and ADS-B are similar modern methods of secondary surveillance. Overview Primary radar The rapid wartime development of radar had obvious applications for air traffic control (ATC) as a means of providing continuous surveillance of air traffic dispositio ...

Identification Friend Or Foe
Identification, friend or foe (IFF) is an identification system designed for command and control. It uses a transponder that listens for an ''interrogation'' signal and then sends a ''response'' that identifies the broadcaster. IFF systems usually use radar frequencies, but other electromagnetic frequencies, radio or infrared, may be used. It enables military and civilian air traffic control interrogation systems to identify aircraft, vehicles or forces as friendly and to determine their bearing and range from the interrogator. IFF is used by both military and civilian aircraft. IFF was first developed during World War II, with the arrival of radar, and several friendly fire incidents. IFF can only positively identify friendly aircraft or other forces. If an IFF interrogation receives no reply or an invalid reply, the object is not positively identified as foe; friendly forces may not properly reply to IFF for various reasons such as equipment malfunction, and parties in the area ...

Port (nautical)
Port and starboard are nautical terms for watercraft and aircraft, referring respectively to the left and right sides of the vessel, when aboard and facing the bow (front). Vessels with bilateral symmetry have left and right halves which are mirror images of each other. One asymmetric feature is where access to a boat, ship, or aircraft is at the side, it is usually only on the port side (hence the name). Side Port and starboard unambiguously refer to the left and right side of the vessel, not the observer. That is, the port side of the vessel always refers to the same portion of the vessel's structure, and does not depend on which way the observer is facing. The port side is the side of the vessel which is to the left of an observer aboard the vessel and , that is, facing forward towards the direction the vehicle is heading when underway, and starboard side is to the right of such an observer. This convention allows orders and information to be given unambiguously, without ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
