1 November 1944 Reconnaissance Sortie Over Japan
On 1 November 1944, a United States Army Air Forces (USAAF) F-13 Superfortress conducted the first flight by an Allied aircraft over the Tokyo region of Japan since the Doolittle Raid in April 1942. This photo reconnaissance sortie returned with 7000 photographs which helped with planning air raids on Japan during the last months of World War II. Attempts by Japanese air units and anti-aircraft gun batteries to shoot down the F-13 failed, as the available fighter aircraft and guns could not reach the high altitude at which it operated. Background In late 1944 the United States Twentieth Air Force's XXI Bomber Command prepared to conduct strategic bombing raids on the Japanese home islands from bases in the Mariana Islands. These attacks were to replace the largely unsuccessful Operation Matterhorn raids which had been conducted by XX Bomber Command aircraft based in India and staging through bases in China since June 1944. While XX Bomber Command conducted photo reconnaissance ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air Raids On Japan
Air raids conducted by Allied forces on Japan during World War II caused extensive destruction to the country's cities and killed between 241,000 and 900,000 people. During the first years of the Pacific War these attacks were limited to the Doolittle Raid in April 1942 and small-scale raids on military positions in the Kuril Islands from mid-1943. Strategic bombing raids began in June 1944 and continued until the end of the war in August 1945. Allied naval and land-based tactical air units also attacked Japan during 1945. The United States military air campaign waged against Japan began in earnest in mid-1944 and intensified during the war's last months. While plans for attacks on Japan had been prepared prior to the Pacific War, these could not begin until the long-range B-29 Superfortress bomber was ready for combat. From June 1944 until January 1945, B-29s stationed in India staged through bases in China to make a series of nine raids on targets in western Japan, but this ...

Oahu
Oahu () (Hawaiian language, Hawaiian: ''Oʻahu'' ()), also known as "The Gathering place#Island of Oʻahu as The Gathering Place, Gathering Place", is the third-largest of the Hawaiian Islands. It is home to roughly one million people—over two-thirds of the population of the U.S. state of Hawaii. The island of O’ahu and the Northwestern Hawaiian Islands constitute the City and County of Honolulu, Hawaii, City and County of Honolulu. The state capital, Honolulu, is on Oʻahu's southeast coast. Oʻahu had a population of 1,016,508 according to the 2020 U.S. Census, up from 953,207 people in 2010 (approximately 70% of the total 1,455,271 population of the State of Hawaii, with approximately 81% of those living in or near the Honolulu urban area). Name The Island of O{{okinaahu in Hawaii is often nicknamed (or translated as) ''"The Gathering Place"''. It appears that O{{okinaahu grew into this nickname; it is currently the most populated Hawaiian islands, Hawaiian Island, how ...

Photographic Processing
Photographic processing or photographic development is the chemical means by which photographic film or paper is treated after photographic exposure to produce a negative or positive image. Photographic processing transforms the latent image into a visible image, makes this permanent and renders it insensitive to light.Karlheinz Keller et al. "Photography" in Ullmann's Encyclopedia of Industrial Chemistry, 2005, Wiley-VCH, Weinheim. All processes based upon the gelatin silver process are similar, regardless of the film or paper's manufacturer. Exceptional variations include instant films such as those made by Polaroid and thermally developed films. Kodachrome required Kodak's proprietary K-14 process. Kodachrome film production ceased in 2009, and K-14 processing is no longer available as of December 30, 2010. Ilfochrome materials use the dye destruction process. Deliberately using the wrong process for a film is known as cross processing. Common processes All photographic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Tokyo Rose
Tokyo Rose (alternative spelling Tokio Rose) was a name given by Allied troops in the South Pacific during World War II to all female English-speaking radio broadcasters of Japanese propaganda. The programs were broadcast in the South Pacific and North America to demoralize Allied forces abroad and their families at home by emphasizing troops' wartime difficulties and military losses.Berg, Jerome S. ''The Early Shortwave Stations: A Broadcasting History Through 1945''. Jefferson: McFarland, 2013. ''CREDO Reference''. Web. Retrieved 5 March 2017. p.205. Several female broadcasters operated using different aliases and in different cities throughout the territories occupied by the Japanese Empire, including Tokyo, Manila, and Shanghai. The name "Tokyo Rose" was never actually used by any Japanese broadcaster, but it first appeared in U.S. newspapers in the context of these radio programs during 1943. During the war, Tokyo Rose was not any one individual, but rather a group of lar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nakajima Ki-44
The Nakajima Ki-44 ''Shoki'' (鍾馗, " Devil Queller") was a single-seat fighter-interceptor which was developed by the Nakajima Aircraft Company and operated by the Imperial Japanese Army from 1942 to 1945 during World War II. Its official designation was Army Type 2 Single-Seat Fighter (二式単座戦闘機) and its Allied reporting name was Tojo. The design and development of the Ki-44 differed greatly from that of other Japanese fighters of the time, incorporating speed and rate-of-climb in preference to maneuverability.Millman, 2011, pp.1–8 This was a result of a need for a heavy fighter aircraft that followed a more offensive doctrine and the Ki-44 is often classified as an Air Defence Fighter.Bueschel, 1971 Its development ran almost in parallel to its predecessor, the lighter and nimbler Nakajima Ki-43, and yet the two aircraft differed. The Ki-44 had a higher landing speed but was less maneuverable. These were concerns for pilots who would compare it to the Ki-43 ...

Sentai
In Japanese, is a military unit and may be literally translated as "squadron", " task force", " division (of ships)", "group" or "wing". The terms "regiment" and "flotilla", while sometimes used as translations of ''sentai'', are also used to refer to larger formations. Imperial Japanese aviation ''sentai'' The term was used during World War II by the military of the Empire of Japan for Imperial Japanese Army Air Service (IJAAS) and Imperial Japanese Navy Air Service (IJNAS) military aviation units equivalent to a group or wing in other air forces. However, the term had slightly different meanings in the IJAAS and the IJNAS. An IJAAS ''Sentai'' was made up of two to four squadrons (''chūtai''). In the IJAAS, two or more ''Sentai'' comprised a ''hikōdan'' (air brigade). In the later stages of World War II, the IJAAS abolished ''chūtai'' and divided its ''sentai'' into '' hikōtai'' (flying units) and ''seibitai'' (maintenance units).

Imperial Japanese Army Air Service
The Imperial Japanese Army Air Service (IJAAS) or Imperial Japanese Army Air Force (IJAAF; ja, 大日本帝國陸軍航空部隊, Dainippon Teikoku Rikugun Kōkūbutai, lit=Greater Japan Empire Army Air Corps) was the aviation force of the Imperial Japanese Army (IJA). Just as the IJA in general was modeled mainly on the German Army, the IJAAS initially developed along similar lines to the Imperial German Army Aviation; its primary mission was to provide tactical close air support for ground forces, as well as a limited air interdiction capability. The IJAAS also provided aerial reconnaissance to other branches of the IJA. While the IJAAS engaged in strategic bombing of cities such as Shanghai, Nanking, Canton, Chongqing, Rangoon, and Mandalay, this was not the primary mission of the IJAAS, and it lacked a heavy bomber force. It did not usually control artillery spotter/observer aircraft; artillery battalions controlled the light aircraft and balloons that operated in the ...

Jet Stream
Jet streams are fast flowing, narrow, meandering thermal wind, air currents in the Atmosphere of Earth, atmospheres of some planets, including Earth. On Earth, the main jet streams are located near the altitude of the tropopause and are westerly winds (flowing west to east). Jet streams may start, stop, split into two or more parts, combine into one stream, or flow in various directions including opposite to the direction of the remainder of the jet. Overview The strongest jet streams are the polar jets around the Polar vortex, polar vortices, at above sea level, and the higher altitude and somewhat weaker subtropical jets at . The Northern Hemisphere and the Southern Hemisphere each have a polar jet and a subtropical jet. The northern hemisphere polar jet flows over the middle to northern latitudes of North America, Europe, and Asia and their intervening oceans, while the southern hemisphere polar jet mostly circles Antarctica, both all year round. Jet streams are the prod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ground Speed
Ground speed is the horizontal speed of an aircraft relative to the Earth’s surface. It is vital for accurate navigation that the pilot has an estimate of the ground speed that will be achieved during each leg of a flight. An aircraft diving vertically would have a ground speed of zero. Information displayed to passengers through the entertainment system of airline aircraft usually gives the aircraft ground speed rather than airspeed. Ground speed can be determined by the vector sum of the aircraft's true airspeed and the current wind speed and direction; a headwind subtracts from the ground speed, while a tailwind adds to it. Winds at other angles to the heading will have components of either headwind or tailwind as well as a crosswind component. An airspeed indicator indicates the aircraft's speed relative to the air mass. The air mass may be moving over the ground due to wind, and therefore some additional means to provide position over the ground is required. This might be ...

Nagoya
is the largest city in the Chūbu region, the fourth-most populous city and third most populous urban area in Japan, with a population of 2.3million in 2020. Located on the Pacific coast in central Honshu, it is the capital and the most populous city of Aichi Prefecture, and is one of Japan's major ports along with those of Tokyo, Osaka, Kobe, Yokohama, and Chiba. It is the principal city of the Chūkyō metropolitan area, which is the third-most populous metropolitan area in Japan with a population of 10.11million in 2020. In 1610, the warlord Tokugawa Ieyasu, a retainer of Oda Nobunaga, moved the capital of Owari Province from Kiyosu to Nagoya. This period saw the renovation of Nagoya Castle. The arrival of the 20th century brought a convergence of economic factors that fueled rapid growth in Nagoya, during the Meiji Restoration, and became a major industrial hub for Japan. The traditional manufactures of timepieces, bicycles, and sewing machines were followed by th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
