2010 Alaska USAF C-17 Crash
On July 28, 2010, a C-17 Globemaster III transport plane of the U.S. Air Force (USAF) crashed at Elmendorf Air Force Base in Alaska, while practicing for a flight display at the upcoming Arctic Thunder Air Show. All four crew members on board were killed. It is the only fatal accident of a C-17 aircraft. The subsequent investigation blamed pilot error for the low-altitude Stall (fluid dynamics), stall that led to the crash. Accident On July 28, 2010, the crew was conducting a local training flight in preparation for the upcoming Arctic Thunder Air Show, to be held at the Elmendorf AFB from 31 July to 1 August. The C-17 is commonly featured in U.S. air shows, highlighting its short takeoff and landing capability. The plane had flown earlier that day with a different crew. At approximately 6:22 p.m. Alaska Daylight Time (UTC-8), the C-17 took off from Runway 06 at Elmendorf AFB to practice the display routine. After the initial climb, followed by a left turn, the pilot ex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stall (fluid Dynamics)
In fluid dynamics, a stall is a reduction in the lift coefficient generated by a foil as angle of attack exceeds its critical value.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', p. 486. Aviation Supplies & Academics, 1997. The critical angle of attack is typically about 15°, but it may vary significantly depending on the fluid, foil – including its shape, size, and finish – and Reynolds number. Stalls in fixed-wing aircraft are often experienced as a sudden reduction in lift. It may be caused either by the pilot increasing the wing's angle of attack or by a decrease in the critical angle of attack. The former may be due to slowing down (below stall speed), the latter by accretion of ice on the wings (especially if the ice is rough). A stall does not mean that the engine(s) have stopped working, or that the aircraft has stopped moving—the effect is the same even in an unpowered glider aircraft. Vectored thrust in aircraft is used to maintain al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air Force Reserve
The Air Force Reserve Command (AFRC) is a major command (MAJCOM) of the United States Air Force, with its headquarters at Robins Air Force Base, Georgia. It is the federal Air Reserve Component (ARC) of the U.S. Air Force, consisting of commissioned officers and enlisted airmen. Together, the Air Force Reserve and the Air National Guard constitute the Air Force element of the reserve components of the United States Armed Forces. AFRC also plays an integral role in the day-to-day Air Force mission and is not strictly a force held in reserve for possible war or contingency operations. AFRC also supports the United States Space Force through the 310th Space Wing, pending the creation of a space reserve component. Overview The federal reserve component of the United States Air Force, AFRC has approximately 450 aircraft assigned for which it has sole control, as well as access to several hundred additional active duty USAF aircraft via AFRC "Associate" wings that are collocated ...

2010 Alaska USAF C-17 Crash Report
1 (one, unit, unity) is a number, numeral, and glyph. It is the first and smallest positive integer of the infinite sequence of natural numbers. This fundamental property has led to its unique uses in other fields, ranging from science to sports, where it commonly denotes the first, leading, or top thing in a group. 1 is the unit of counting or measurement, a determiner for singular nouns, and a gender-neutral pronoun. Historically, the representation of 1 evolved from ancient Sumerian and Babylonian symbols to the modern Arabic numeral. In mathematics, 1 is the multiplicative identity, meaning that any number multiplied by 1 equals the same number. 1 is by convention not considered a prime number. In digital technology, 1 represents the "on" state in binary code, the foundation of computing. Philosophically, 1 symbolizes the ultimate reality or source of existence in various traditions. In mathematics The number 1 is the first natural number after 0. Each natural number, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Loadmaster
A loadmaster is an aircrew member on military transport aircraft or civilian aircraft (with cargo ramp) tasked with the safe loading, transport and unloading of aerial cargoes. Loadmasters serve in the militaries and civilian airlines of many nations. Duties The Loadmaster role involves complex mathematical and engineering calculations to ensure aircraft balance and safety throughout a flight. Loadmasters utilize physics, moments, engineering formulas, charts, graphs, and heavily applied basic algebra and trigonometry mathematics to determine the proper placement of cargo and passengers, ensuring the aircraft remains within permissible center of gravity limits. These skilled and certified weight and balance planners act as aviation engineering technicians (devoid of this title), with many holding an Associate in Applied Science (AAS) in Aviation Operations, which provides the foundational knowledge necessary for this technical job. While not all loadmasters officially obtain t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

JOINT BASE ELMENDORF-RICHARDSON, Alaska – Wreckage Of 3rd Wing C-17 Globemaster III
A joint or articulation (or articular surface) is the connection made between bones, ossicles, or other hard structures in the body which link an animal's skeletal system into a functional whole.Saladin, Ken. Anatomy & Physiology. 7th ed. McGraw-Hill Connect. Webp.274/ref> They are constructed to allow for different degrees and types of movement. Some joints, such as the knee, elbow, and shoulder, are self-lubricating, almost frictionless, and are able to withstand compression and maintain heavy loads while still executing smooth and precise movements. Other joints such as sutures between the bones of the skull permit very little movement (only during birth) in order to protect the brain and the sense organs. The connection between a tooth and the jawbone is also called a joint, and is described as a fibrous joint known as a gomphosis. Joints are classified both structurally and functionally. Joints play a vital role in the human body, contributing to movement, stability, and ov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
