Matthew Bacon Sellers Jr.
Matthew Bacon Sellers Jr. (March 29, 1869 – April 5, 1932) was a United States inventor and scientist known for pioneering work with airplanes. Sellers was the son of a prosperous Baltimore merchant family originally from Kentucky. He attended Harvard University and showed an early interest in the burgeoning field of aviation. Only 5 years after the historic Wright Brothers flight, he built and flew his own airplane, making such innovations as the first patent on retractable landing gear, and an ultra-lightweight design. He contributed to scientific papers and was on a founding federal body that eventually became NASA. After a series of personal misfortunes and accidents, and a relatively early death, by the 1930s he largely disappeared from public view. His work was rediscovered in the 1970s, and today he has holdings in the Smithsonian Museum, and has been called Kentucky's version of the Wright Brothers. In 1908, he built and flew the first airplane in Kentucky. Biograp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

First Flight
The maiden flight, also known as first flight, of an aircraft is the first occasion on which it leaves the ground under its own power. The same term is also used for the first launch of rockets. The maiden flight of a new aircraft type is always a historic occasion for the type and can be quite emotional for those involved. In the early days of aviation it could be dangerous, because the exact handling characteristics of the aircraft were generally unknown. The maiden flight of a new type is almost invariably flown by a highly experienced test pilot. Maiden flights are usually accompanied by a chase plane, to verify items like altitude, airspeed, and general airworthiness. A maiden flight is only one stage in the development of an aircraft type. Unless the type is a pure research aircraft (such as the X-15), the aircraft must be tested extensively to ensure that it delivers the desired performance with an acceptable margin of safety. In the case of civilian aircraft, a new type ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pulmonary Embolism
Pulmonary embolism (PE) is a blockage of an artery in the lungs by a substance that has moved from elsewhere in the body through the bloodstream (embolism). Symptoms of a PE may include shortness of breath, chest pain particularly upon breathing in, and coughing up blood. Symptoms of a blood clot in the leg may also be present, such as a red, warm, swollen, and painful leg. Signs of a PE include low blood oxygen levels, rapid breathing, rapid heart rate, and sometimes a mild fever. Severe cases can lead to passing out, abnormally low blood pressure, obstructive shock, and sudden death. PE usually results from a blood clot in the leg that travels to the lung. The risk of blood clots is increased by advanced age, cancer, prolonged bed rest and immobilization, smoking, stroke, long-haul travel over 4 hours, certain genetic conditions, estrogen-based medication, pregnancy, obesity, trauma or bone fracture, and after some types of surgery. A small proportion of cases are due ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Crash Of '29
The Wall Street Crash of 1929, also known as the Great Crash, was a major American stock market crash that occurred in the autumn of 1929. It started in September and ended late in October, when share prices on the New York Stock Exchange collapsed. It was the most devastating stock market crash in the history of the United States, when taking into consideration the full extent and duration of its aftereffects. The Great Crash is mostly associated with October 24, 1929, called ''Black Thursday'', the day of the largest sell-off of shares in U.S. history, and October 29, 1929, called ''Black Tuesday'', when investors traded some 16 million shares on the New York Stock Exchange in a single day. The crash, which followed the London Stock Exchange's crash of September, signaled the beginning of the Great Depression. Background The " Roaring Twenties", the decade following World War I that led to the crash, was a time of wealth and excess. Building on post-war optimism, rural A ...

Naval Consulting Board
The Naval Consulting Board, also known as the Naval Advisory Board (a name used in the 1880s for two previous committees), was a US Navy organization established in 1915 by Josephus Daniels, the Secretary of the Navy at the suggestion of Thomas Alva Edison. Daniels created the Board with membership drawn from eleven engineering and scientific organizations two years before the United States entered World War I to provide the country with the "machinery and facilities for utilizing the natural inventive genius of Americans to meet the new conditions of warfare." Daniels was concerned that the U.S. was unprepared for the new conditions of warfare and that they needed access to the newest technology. History Thomas Edison gave a speech in which he proposed a group of scientists should be involved with the World War I effort. In a statement issued in the ''New York Times'' on September 13, 1915, Josephus Daniels, the Secretary of the Navy asked Thomas Edison to be president of an ...

Aeronautical Society Of America
Aeronautics is the science or art involved with the study, design, and manufacturing of air flight–capable machines, and the techniques of operating aircraft and rockets within the atmosphere. The British Royal Aeronautical Society identifies the aspects of "aeronautical Art, Science and Engineering" and "The profession of Aeronautics (which expression includes Astronautics)." While the term originally referred solely to ''operating'' the aircraft, it has since been expanded to include technology, business, and other aspects related to aircraft. The term "aviation" is sometimes used interchangeably with aeronautics, although "aeronautics" includes lighter-than-air craft such as airships, and includes ballistic vehicles while "aviation" technically does not. A significant part of aeronautical science is a branch of dynamics called aerodynamics, which deals with the motion of air and the way that it interacts with objects in motion, such as an aircraft.
