General Henry H. Arnold
Henry Harley Arnold (June 25, 1886 – January 15, 1950) was an American general officer holding the ranks of General of the Army and later, General of the Air Force. Arnold was an aviation pioneer, Chief of the Air Corps (1938–1941), commanding general of the United States Army Air Forces, the only United States Air Force general to hold five-star rank, and the only officer to hold a five-star rank in two different U.S. military services. Arnold was also the founder of Project RAND, which evolved into one of the world's largest non-profit global policy think tanks, the RAND Corporation, and was one of the founders of Pan American World Airways. Instructed in flying by the Wright Brothers, Arnold was one of the first military pilots worldwide, and one of the first three rated pilots in the history of the United States Air Force.Arnold, Capt.

General Of The Army (United States)
General of the Army (abbreviated as GA) is a five-star general officer and the second-highest possible rank in the United States Army. It is generally equivalent to the rank of Field Marshal in other countries. In the United States, a General of the Army ranks above generals and is equivalent to a fleet admiral and a general of the Air Force. The General of the Army insignia consisted of five stars in a pentagonal pattern, with touching points. The insignia was paired with the gold and enameled United States Coat of Arms on service coat shoulder loops. The silver colored five-star metal insignia alone would be worn for use as a collar insignia of grade and on the garrison cap. Soft shoulder epaulettes with five stars in silver thread and gold-threaded United States Coat of Arms on green cloth were worn with shirts and sweaters. The rank of "General of the Army" has had two incarnations. The first was introduced in 1866, following the American Civil War. It was a four-star ...

Distinguished Flying Cross (United States)
The Distinguished Flying Cross (DFC) is a military decoration of the United States Armed Forces. The medal was established on July 2, 1926, and is currently awarded to any persons who, after April 6, 1917, distinguish themselves by single acts of heroism or extraordinary achievement while participating in aerial flight. Both heroism and extraordinary achievement are entirely distinctive, involving operations that are not routine. The medal may be awarded to friendly foreign military members in ranks equivalent to U.S. Pay Grade of O-6 and below, in actual combat in support operations. History The first award of the Distinguished Flying Cross was made by President Calvin Coolidge on May 2, 1927, to ten aviators of the U.S. Army Air Corps who had participated in the Army Pan American Flight which took place from December 21, 1926, to May 2, 1927. Two of the airmen died in a mid-air collision trying to land at Buenos Aires on February 26, 1927, and received their awards posthumousl ...

Airlift
An airlift is the organized delivery of supplies or personnel primarily via military transport aircraft. Airlifting consists of two distinct types: strategic and tactical. Typically, strategic airlifting involves moving material long distances (such as across or off the continent or theater), whereas a tactical airlift focuses on deploying resources and material into a specific location with high precision. Depending on the situation, airlifted supplies can be delivered by a variety of means. When the destination and surrounding airspace is considered secure, the aircraft will land at an appropriate airport or airbase to have its cargo unloaded on the ground. When landing the craft or distributing the supplies to a certain area from a landing zone by surface transportation is not an option, the cargo aircraft can drop them in mid-flight using parachutes attached to the supply containers in question. When there is a broad area available where the intended receivers have c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radar
Radar is a detection system that uses radio waves to determine the distance (''ranging''), angle, and radial velocity of objects relative to the site. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving information about the objects' locations and speeds. Radar was developed secretly for military use by several countries in the period before and during World War II. A key development was the cavity magnetron in the United Kingdom, which allowed the creation of relatively small systems with sub-meter resolution. Th ...

Research And Development
Research and development (R&D or R+D), known in Europe as research and technological development (RTD), is the set of innovative activities undertaken by corporations or governments in developing new services or products, and improving existing ones. Research and development constitutes the first stage of development of a potential new service or the production process. R&D activities differ from institution to institution, with two primary models of an R&D department either staffed by engineers and tasked with directly developing new products, or staffed with industrial scientists and tasked with applied research in scientific or technological fields, which may facilitate future product development. R&D differs from the vast majority of corporate activities in that it is not intended to yield immediate profit, and generally carries greater risk and an uncertain return on investment. However R&D is crucial for acquiring larger shares of the market through the marketisation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Billy Mitchell
William Lendrum Mitchell (December 29, 1879 – February 19, 1936) was a United States Army officer who is regarded as the father of the United States Air Force. Mitchell served in France during World War I and, by the conflict's end, commanded all American air combat units in that country. After the war, he was appointed deputy director of the Air Service and began advocating increased investment in air power, believing that this would prove vital in future wars. He argued particularly for the ability of bombers to sink battleships and organized a series of bombing runs against stationary ships designed to test the idea. He antagonized many administrative leaders of the Army with his arguments and criticism and in 1925, his temporary appointment as a brigadier general was not renewed, and he reverted to his permanent rank of colonel, due to his insubordination. Later that year, he was court-martialed for insubordination after accusing Army and Navy leaders of an "almost trea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fear Of Flying
Fear of flying is a fear of being on an airplane, or other flying vehicle, such as a helicopter, while in flight. It is also referred to as flying anxiety, flying phobia, flight phobia, aviophobia, aerophobia, or pteromechanophobia (although aerophobia also means a fear of drafts or of fresh air). Acute anxiety caused by flying can be treated with anti-anxiety medication. The condition can be treated with exposure therapy, which works better when combined with cognitive behavioral therapy. Signs and symptoms People with fear of flying experience intense, persistent fear or anxiety when they consider flying, as well as during flying. They will avoid flying if they can, and the fear, anxiety, and avoidance cause significant distress and impair their ability to function. Take-off, bad weather, and turbulence appear to be the most anxiety provoking aspects of flying. The most extreme manifestations can include panic attacks or vomiting at the mere sight or mention of an aircra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Air Force Aeronautical Ratings
U.S. Air Force aeronautical ratings are military aviation skill standards established and awarded by the United States Air Force for commissioned officers participating in "regular and frequent flight",The standard by which flight status has been defined in law, executive orders, and regulations since 1913. either aerially or in space, in performance of their duties. USAF aeronautical badges, commonly referred to as "wings" from their shape and their historical legacy, are awarded by the Air Force in recognition of degrees of achievement and experience. Officers earning these badges and maintaining their requirements are classified as rated officers and receive additional pay and allowances. The first U.S. military aviator ratings were awarded in 1912, and the issuance of badges for recognition of the award began in 1913. The division of ratings into multiple skill levels and categories began in 1914 and expanded during World War I. With minor variations in numbers and titles of ...

Pan American World Airways
Pan American World Airways, originally founded as Pan American Airways and commonly known as Pan Am, was an American airline that was the principal and largest international air carrier and unofficial overseas flag carrier of the United States for much of the 20th century. It was the first airline to fly worldwide and pioneered numerous innovations of the modern airline industry such as Wide-body aircraft, jumbo jets, and computerized reservation systems. Until its dissolution in 1991, Pan Am "epitomized the luxury and glamour of intercontinental travel", and it remains a cultural icon of the 20th century, identified by its blue globe logo ("The Blue Meatball"), the use of the word "Clipper" in its aircraft names and call signs, and the white uniform caps of its pilots. Founded in 1927 by two former U.S. Army Air Corps majors, Pan Am began as a scheduled airmail and passenger service flying between Key West, Florida, and Havana, Cuba.
