Frank S. Scott
Frank S. Scott (2 December 188328 September 1912) was a United States Army corporal who died during his second enlistment, aged 28, in an aircraft crash. As the first enlisted American to die in an aircraft incident, Scott was memorialized multiple times. Personal life Frank S. Scott was born in Braddock, Pennsylvania on 2 December 1883. He and his sister Clara were orphaned in 1889 when their parents died in the Johnstown Flood; they were thereafter raised by an aunt. US Army Scott enlisted in the United States Army at Fort Slocum on 2 March 1908, and served with the Field Artillery Branch. In 1911, Private Scott was discharged at Fort Myer (with "excellent"-rated character) from "Battery D, 3rd Regiment, Field Artillery." The very same month, he re-enlisted with "Company G, Signal Corps." That July, then- Corporal Scott began suffering from a lengthy unknown illness. Upon recovery, he was deemed unfit for his current duties and transferred to the Signal Corps' A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Braddock, Pennsylvania
Braddock is a borough located in the eastern suburbs of Pittsburgh in Allegheny County, Pennsylvania. It is upstream from the mouth of the Monongahela River. The population was 1,721 as of the 2020 census. The borough is represented by the Pennsylvania State Senate's 45th district, the Pennsylvania House of Representatives' 34th district, and in the U.S. House of Representatives. History Braddock is named for General Edward Braddock (1695–1755), commander of American colonial forces at the start of the French and Indian War. The Braddock Expedition to capture Fort Duquesne (modern day Pittsburgh) from the French led to the British general's own fatal wounding and a sound defeat of his troops after crossing the Monongahela River on July 9, 1755. This battle, now called the Battle of the Monongahela, was a key event at the beginning of the French and Indian War. The area surrounding Braddock's Field was originally inhabited by the Lenape, ruled by Queen Alliquippa. In 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aeronautical Division, U
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.

Descent (aeronautics)
In aeronautics, a descent is any time period during air travel where an aircraft decreases altitude, and is the opposite of an ''ascent'' or '' climb''. Descents are part of normal procedures, but also occur during emergencies, such as rapid or explosive decompression, forcing an emergency descent to below and preferably below , respectively the maximum temporary safe altitude for an unpressurized aircraft and the maximum safe altitude for extended duration. An example of explosive decompression is Aloha Airlines Flight 243. Involuntary descent might occur from a decrease in power, decreased lift (wing icing), an increase in drag, or flying in an air mass moving downward, such as a terrain induced downdraft, near a thunderstorm, in a downburst, or microburst. Normal descents Intentional descents might be undertaken to land, avoid other air traffic or poor flight conditions (turbulence, icing conditions, or bad weather), clouds (particularly under visual flight rules), to se ...

Takeoff
Takeoff is the phase of flight in which an aerospace vehicle leaves the ground and becomes airborne. For aircraft traveling vertically, this is known as liftoff. For aircraft that take off horizontally, this usually involves starting with a transition from moving along the ground on a runway. For balloons, helicopters and some specialized fixed-wing aircraft (VTOL aircraft such as the Harrier and the Bell Boeing V22 Osprey), no runway is needed. Horizontal Power settings For light aircraft, usually full power is used during takeoff. Large transport category (airliner) aircraft may use a reduced power for takeoff, where less than full power is applied in order to prolong engine life, reduce maintenance costs and reduce noise emissions. In some emergency cases, the power used can then be increased to increase the aircraft's performance. Before takeoff, the engines, particularly piston engines, are routinely run up at high power to check for engine-related problems. The airc ...

Ballast
Ballast is material that is used to provide stability to a vehicle or structure. Ballast, other than cargo, may be placed in a vehicle, often a ship or the gondola of a balloon or airship, to provide stability. A compartment within a boat, ship, submarine, or other floating structure that holds water is called a ballast tank. Water should move in and out from the ballast tank to balance the ship. In a vessel that travels on the water, the ballast will remain below the water level, to counteract the effects of weight above the water level. The ballast may be redistributed in the vessel or disposed of altogether to change its effects on the movement of the vessel. History The basic concept behind the ballast tank can be seen in many forms of aquatic life, such as the blowfish or members of the argonaut group of octopus. The concept has been invented and reinvented many times by humans to serve a variety of purposes. In the fifteenth and sixteenth century, the ballast "did not cons ...

Captain (United States O-3)
In the United States Army (), U.S. Marine Corps (USMC), U.S. Air Force (USAF), and U.S. Space Force (USSF), captain (abbreviated "CPT" in the and "Capt" in the USMC, USAF, and USSF) is a company-grade officer rank, with the pay grade of O-3. It ranks above first lieutenant and below major. It is equivalent to the rank of lieutenant in the Navy/Coast Guard officer rank system and should not be confused with the Navy/Coast Guard rank of captain. The insignia for the rank consists of two silver bars, with slight stylized differences between the Army/Air Force version and the Marine Corps version. History The U.S. military inherited the rank of captain from its British Army forebears. In the British Army, the captain was designated as the appropriate rank for the commanding officer of infantry companies, artillery batteries, and cavalry troops, which were considered as equivalent-level units. Captains also served as staff officers in regimental and brigade headquarters ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Second Lieutenant
Second lieutenant is a junior commissioned officer military rank in many armed forces, comparable to NATO OF-1 rank. Australia The rank of second lieutenant existed in the military forces of the Australian colonies and Australian Army until 1986. In the colonial forces, which closely followed the practices of the British military, the rank of second lieutenant began to replace ranks such as ensign and cornet from 1871. New appointments to the rank of second lieutenant ceased in the regular army in 1986. Immediately prior to this change, the rank had been effectively reserved for new graduates from the Officer Cadet School, Portsea which closed in 1985. (Graduates of the Australian Defence Force Academy (ADFA) and the Royal Military College, Duntroon (RMC-D) are commissioned as lieutenants.). The rank of second lieutenant is only appointed to officers in special appointments such as training institutions, university regiments and while under probation during training. Trai ...

Biplane
A biplane is a fixed-wing aircraft with two main wings stacked one above the other. The first powered, controlled aeroplane to fly, the Wright Flyer, used a biplane wing arrangement, as did many aircraft in the early years of aviation. While a biplane wing structure has a structural advantage over a monoplane, it produces more drag than a monoplane wing. Improved structural techniques, better materials and higher speeds made the biplane configuration obsolete for most purposes by the late 1930s. Biplanes offer several advantages over conventional cantilever monoplane designs: they permit lighter wing structures, low wing loading and smaller span for a given wing area. However, interference between the airflow over each wing increases drag substantially, and biplanes generally need extensive bracing, which causes additional drag. Biplanes are distinguished from tandem wing arrangements, where the wings are placed forward and aft, instead of above and below. The term is also ...

Wright Model B
The Wright Model B was an early pusher biplane designed by the Wright brothers in the United States in 1910. It was the first of their designs to be built in quantity. Unlike the Model A, it featured a true elevator carried at the tail rather than at the front. It was the last Wright model to have an open-frame tail. The Model B was a dedicated two-seater with the pilot and a passenger sitting side by side on the leading edge of the lower wing. Besides their civil market, the Wrights were able to sell aircraft to the Aeronautical Division, U.S. Signal Corps (S.C. 3, 4, and 5) and to the United States Navy as hydroplanes (AH-4, -5-, and -6), in which services they were used as trainers. Furthermore, the Wrights were able to sell licenses to produce the aircraft domestically (to the Burgess Company and Curtis, which designated it Model F), as well as in Germany. The deal with Burgess was the first license-production of aircraft undertaken in the United States and most of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mechanic
A mechanic is an artisan, skilled tradesperson, or technician who uses tools to build, maintain, or repair machinery, especially cars. Duties Most mechanics specialize in a particular field, such as auto body mechanics, air conditioning and refrigeration mechanics, auto mechanics, bicycle mechanics, boiler mechanics, and other areas. A mechanic is typically certified by a trade association or regional government power. Mechanics may be separated into two classes based on the type of machines they work on, heavyweight and lightweight. Heavyweight work is on larger machines or heavy equipment, such as tractors and trailers, while lightweight work is on smaller items, such as automotive engines. Automotive mechanics/automotive technicians Automotive technicians (the modern term of reference) have many trades within. Some may specialize in the electrical diagnosis, while others may specialize in the mechanical aspects. Other mechanical areas include: brakes and steering, sus ...
