Twenty-Nine Palms Air Academy
Twentynine Palms Airport is a public use airport located six nautical miles (11 km) east of the central business district of Twentynine Palms, a city in San Bernardino County, California, United States. It is owned by the County of San Bernardino. History It was activated on 1 January 1942 by the United States Army Air Forces. It started as USAAF contract glider training, and was called Twenty-Nine Palms Air Academy until 16 February 1943. It had four axillary airfields in local area, including Condor Field. Flying training was performed with Fairchild PT-19s as the primary trainer. It also had several PT-17 Stearmans and a few P-40 Warhawks assigned. It conducted basic flying training from March 1943 until being transferred to United States Navy April 1944. General Henry H. Arnold, Chief of the Army Air Forces, ordered the training for 150 glider pilots for World War II. By the end of WW2 over 6,000 glider pilots had been trained. In all 1,654 of the glider pilots wer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
USGS
The United States Geological Survey (USGS), formerly simply known as the Geological Survey, is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization's work spans the disciplines of biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility. The agency was founded on March 3, 1879. The USGS is a bureau of the United States Department of the Interior; it is that department's sole scientific agency. The USGS employs approximately 8,670 people and is headquartered in Reston, Virginia. The USGS also has major offices near Lakewood, Colorado, at the Denver Federal Center, and Menlo Park, California.

P-40 Warhawk
The Curtiss P-40 Warhawk is an American single-engined, single-seat, all-metal fighter and ground-attack aircraft that first flew in 1938. The P-40 design was a modification of the previous Curtiss P-36 Hawk which reduced development time and enabled a rapid entry into production and operational service. The Warhawk was used by most Allied powers during World War II, and remained in frontline service until the end of the war. It was the third most-produced American fighter of World War II, after the P-51 and P-47; by November 1944, when production of the P-40 ceased, 13,738 had been built,Murphy and McNiece 2009, p. 83. all at Curtiss-Wright Corporation's main production facilities in Buffalo, New York. P-40 Warhawk was the name the United States Army Air Corps gave the plane, and after June 1941, the USAAF adopted the name for all models, making it the official name in the U.S. for all P-40s. The British Commonwealth and Soviet air forces used the name Tomahawk for models eq ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Airfields Of The United States Army Air Forces In California
An aerodrome (Commonwealth English) or airdrome (American English) is a location from which aircraft flight operations take place, regardless of whether they involve air cargo, passengers, or neither, and regardless of whether it is for public or private use. Aerodromes include small general aviation airfields, large commercial airports, and military air bases. The term ''airport'' may imply a certain stature (having satisfied certain certification criteria or regulatory requirements) that not all aerodromes may have achieved. That means that all airports are aerodromes, but not all aerodromes are airports. Usage of the term "aerodrome" remains more common in Ireland and Commonwealth nations, and is conversely almost unknown in American English, where the term "airport" is applied almost exclusively. A water aerodrome is an area of open water used regularly by seaplanes, floatplanes or amphibious aircraft for landing and taking off. In formal terminology, as defined by the I ...

IX Troop Carrier Command
The IX Troop Carrier Command was a United States Army Air Forces unit. Its last assignment was with the Ninth Air Force, based at Greenville Army Air Base, South Carolina. It was inactivated on 31 March 1946. As a component command of the Ninth Air Force, based in the United Kingdom. Overview The mission of IX Troop Carrier Command was air transport for the Allied airborne divisions in the European Theater of Operations. The primary aircraft of command were the Douglas C-47 Skytrain and its variant, the Douglas C-53 Skytrooper, but in 1945 the command equipped one group with 117 Curtiss C-46 Commando aircraft to determine their viability in the European Theater of Operations. As a result of a 28% loss ratio during Operation Varsity resulting from the C-46's high inflammability, The command did not convert to the Commando, even though its cargo-carrying capacity was twice that of the C-47. The command also had 1,922 CG-4A Waco and 20 Waco CG-13 gliders just prior to its last ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
36th Flying Training Wing (World War II)
The 36th Flying Training Wing was a wing of the United States Army Air Forces. It was last assigned to the Western Flying Training Command, and was disbanded on 1 November 1945 at Santa Ana Army Air Base, California. The wing directed flying training units of the Army Air Forces Training Command. Headquartered at Victorville Army Airfield, California for most of its operational service, it controlled contract pilot schools primarily in California and other western states. There is no lineage between the current United States Air Force 36th Wing, established on 17 June 1948 at Howard Field, Canal Zone, and this organization. History Until 1939, the Army Air Corps provided all flying training with military instructor pilots. Beginning in 1939, it contracted with nine civilian flying schools to provide primary flight training. Primary training consisted of a three-month course of 65 hours of flying instruction. As the United States prepared to enter World War II by expandi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
California World War II Army Airfields
During World War II, the United States Army Air Forces (USAAF) established numerous airfields in California for training pilots and aircrews of USAAF fighters and bombers. Most of these airfields were under the command of Fourth Air Force or the Army Air Forces Training Command (AAFTC). However, Air Technical Service Command (ATSC), Air Transport Command (ATC) and I Troop Carrier Command used a significant number of airfields in a support role. A significant number of them had operational squadrons for air defense of the Pacific coastline and anti-submarine patrols, and one was even handed over to Civil Air Patrol pilots for their use. In addition to the major fields, dozens of minor auxiliary fields and airstrips were built, generally to provide more room for basic flight training, but also to support other operations. A few of these were designed as "fallback fields" for launching defensive operations in case of a Japanese invasion. Most Army airfields were built with three runw ...

Glider (sailplane)
A glider or sailplane is a type of glider aircraft used in the leisure activity and sport of gliding (also called soaring). This unpowered aircraft can use naturally occurring currents of rising air in the atmosphere to gain altitude. Sailplanes are aerodynamically streamlined and so can fly a significant distance forward for a small decrease in altitude. In North America the term 'sailplane' is also used to describe this type of aircraft. In other parts of the English-speaking world, the word 'glider' is more common. Types Gliders benefit from producing the least drag for any given amount of lift, and this is best achieved with long, thin wings, a slender fuselage and smooth surfaces with an absence of protuberances. Aircraft with these features are able to soar – climb efficiently in rising air produced by thermals or hills. In still air, sailplanes can glide long distances at high speed with a minimum loss of height in between. Sailplanes have rigid wings and eithe ...

Aircraft Engine
An aircraft engine, often referred to as an aero engine, is the power component of an aircraft propulsion system. Most aircraft engines are either piston engines or gas turbines, although a few have been rocket powered and in recent years many small UAVs have used electric motors. Manufacturing industry In commercial aviation the major Western manufacturers of turbofan engines are Pratt & Whitney (a subsidiary of Raytheon Technologies), General Electric, Rolls-Royce, and CFM International (a joint venture of Safran Aircraft Engines and General Electric). Russian manufacturers include the United Engine Corporation, Aviadvigatel and Klimov. Aeroengine Corporation of China was formed in 2016 with the merger of several smaller companies. The largest manufacturer of turboprop engines for general aviation is Pratt & Whitney. General Electric announced in 2015 entrance into the market.

Military Aviation
Military aviation comprises military aircraft and other flying machines for the purposes of conducting or enabling aerial warfare, including national airlift ( air cargo) capacity to provide logistical supply to forces stationed in a war theater or along a front. Airpower includes the national means of conducting such warfare, including the intersection of transport and warcraft. Military aircraft include bombers, fighters, transports, trainer aircraft, and reconnaissance aircraft. History The first military uses of aviation involved lighter-than-air balloons. During the Battle of Fleurus in 1794, the French observation balloon ''l'Entreprenant'' was used to monitor Austrian troop movements. The use of lighter-than-air aircraft in warfare became prevalent in the 19th century, including regular use in the American Civil War. Lighter-than-air military aviation persisted until shortly after World War II, gradually being withdrawn from various roles as heavier-than-air airc ...

General Aviation
General aviation (GA) is defined by the International Civil Aviation Organization (ICAO) as all civil aviation aircraft operations with the exception of commercial air transport or aerial work, which is defined as specialized aviation services for other purposes. However, for statistical purposes ICAO uses a definition of general aviation which includes aerial work. General aviation thus represents the "private transport" and recreational components of aviation. Definition The International Civil Aviation Organization (ICAO) defines civil aviation aircraft operations in three categories: General Aviation (GA), Aerial Work (AW) and Commercial Air Transport (CAT). Aerial work operations are separated from general aviation by ICAO by this definition. Aerial work is when an aircraft is used for specialized services such as agriculture, construction, photography, surveying, observation and patrol, search and rescue, and aerial advertisement. However, for statistical purposes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Runway
According to the International Civil Aviation Organization (ICAO), a runway is a "defined rectangular area on a land aerodrome prepared for the landing and takeoff of aircraft". Runways may be a man-made surface (often asphalt concrete, asphalt, concrete, or a mixture of both) or a natural surface (sod, grass, soil, dirt, gravel, ice, sand or road salt, salt). Runways, as well as taxiways and Airport apron, ramps, are sometimes referred to as "tarmac", though very few runways are built using Tarmacadam, tarmac. Takeoff and landing areas defined on the surface of water for seaplanes are generally referred to as waterways. Runway lengths are now International Civil Aviation Organization#Use of the International System of Units, commonly given in meters worldwide, except in North America where feet are commonly used. History In 1916, in a World War I war effort context, the first concrete-paved runway was built in Clermont-Ferrand in France, allowing local company Michelin to ...

Asphalt Concrete
Asphalt concrete (commonly called asphalt, blacktop, or pavement in North America, and tarmac, bitumen macadam, or rolled asphalt in the United Kingdom and the Republic of Ireland) is a composite material commonly used to surface roads, parking lots, airports, and the core of embankment dams. Asphalt mixtures have been used in pavement construction since the beginning of the twentieth century. It consists of mineral aggregate bound together with asphalt, laid in layers, and compacted. The process was refined and enhanced by Belgian-American inventor Edward De Smedt. The terms ''asphalt'' (or ''asphaltic'') ''concrete'', ''bituminous asphalt concrete'', and ''bituminous mixture'' are typically used only in engineering and construction documents, which define concrete as any composite material composed of mineral aggregate adhered with a binder. The abbreviation, ''AC'', is sometimes used for ''asphalt concrete'' but can also denote ''asphalt content'' or ''asphalt cement'', ...
