Jiro Horikoshi
was the chief engineer of many Japanese fighter designs of World War II, including the Mitsubishi A6M Zero fighter. Early life Jiro Horikoshi was born near the city of Fujioka, Gunma Prefecture, Japan, in 1903. Horikoshi graduated from the newly established Aviation Laboratory (Kōkū Kenkyūjo) within the Engineering Department of the University of Tokyo, and started his career in Mitsubishi Internal Combustion Engine Company Limited, which later became Mitsubishi Heavy Industries, Nagoya Aircraft Manufacturing Plant. Engineering career One of Jiro Horikoshi's first works was the flawed Mitsubishi 1MF10, an experimental aircraft that never passed the prototype stage after some flight tests. However, lessons learned from this design led to the development of the far more successful Mitsubishi A5M ( Allied codename "Claude") which entered mass production in 1936. In 1937, Horikoshi and his team at Mitsubishi were asked to design Prototype 12 (corresponding to the 12th yea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Shōwa Era
The was the period of Japanese history corresponding to the reign of Emperor Shōwa (Hirohito) from December 25, 1926, until his death on January 7, 1989. It was preceded by the Taishō era. The pre-1945 and post-war Shōwa periods are almost completely different states: the pre-1945 Shōwa era (1926–1945) concerns the Empire of Japan, and post-1945 Shōwa era (1945–1989) concerns the State of Japan. Before 1945, Japan moved into political totalitarianism, ultranationalism and statism culminating in Japan's invasion of China in 1937, part of a global period of social upheavals and conflicts such as the Great Depression and World War II. Defeat in the Second World War brought about radical change in Japan. For the first and only time in its history, Japan was occupied by foreign powers, an American-led occupation which lasted for seven years. Allied occupation brought forth sweeping democratic reforms. It led to the formal end of the emperor's status as a demigod and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bombing Of Nagoya In World War II
The Bombing of Nagoya in World War II by the United States Army Air Forces took place as part of the air raids on Japan during the closing months of the war. History The first strategic bombing attack on Nagoya was on April 18, 1942, as part of the Doolittle Raid. A B-25 bomber targeted the Mitsubishi Aircraft Works, the Matsuhigecho oil warehouse, the Nagoya Castle military barracks, and the Nagoya war industries plant. However, it was not until the aerial attacks of 1944 and 1945 that Nagoya would suffer serious bomb damage. According to the United States Strategic Bombing Survey, during the last 9 months of the Pacific War 14,054 tons of bombs were dropped in precision and area air attacks on the factories and urban areas of Nagoya. No other Japanese city other than Tokyo received as many attacks. The city was attacked 21 times between December 13, 1944 and July 24, 1945. The aim of the attacks was stated as ''"(1) mainly by precision attacks, to wipe out Nagoya's aircra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bombing Of Tokyo (10 March 1945)
On the night of 9/10 March 1945, the United States Army Air Forces (USAAF) conducted a devastating firebombing raid on Tokyo, the Japanese capital city. This attack was code-named Operation Meetinghouse by the USAAF and is known as the Great Tokyo Air Raid in Japan. Bombs dropped from 279 Boeing B-29 Superfortress heavy bombers burned out much of eastern Tokyo. More than 90,000 and possibly over 100,000 Japanese people were killed, mostly civilians, and one million were left homeless, making it the most destructive single air attack in human history. The Japanese air and civil defenses proved largely inadequate; 14 American aircraft and 96 airmen were lost. The attack on Tokyo was an intensification of the air raids on Japan which had begun in June 1944. Prior to this operation, the USAAF had focused on a precision bombing campaign against Japanese industrial facilities. These attacks were generally unsuccessful, which contributed to the decision to shift to firebombing. The ope ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pleurisy
Pleurisy, also known as pleuritis, is inflammation of the membranes that surround the lungs and line the chest cavity ( pleurae). This can result in a sharp chest pain while breathing. Occasionally the pain may be a constant dull ache. Other symptoms may include shortness of breath, cough, fever, or weight loss, depending on the underlying cause. The most common cause is a viral infection. Other causes include bacterial infection, pneumonia, pulmonary embolism, autoimmune disorders, lung cancer, following heart surgery, pancreatitis and asbestosis. Occasionally the cause remains unknown. The underlying mechanism involves the rubbing together of the pleurae instead of smooth gliding. Other conditions that can produce similar symptoms include pericarditis, heart attack, cholecystitis, pulmonary embolism, and pneumothorax. Diagnostic testing may include a chest X-ray, electrocardiogram (ECG), and blood tests. Treatment depends on the underlying cause. Paracetamol (acetaminop ...

B-29
The Boeing B-29 Superfortress is an American four-engined propeller-driven heavy bomber, designed by Boeing and flown primarily by the United States during World War II and the Korean War. Named in allusion to its predecessor, the B-17 Flying Fortress, the Superfortress was designed for high-altitude strategic bombing, but also excelled in low-altitude night incendiary bombing, and in dropping naval mines to blockade Japan. B-29s dropped the atomic bombs on Hiroshima and Nagasaki, the only aircraft ever to drop nuclear weapons in combat. One of the largest aircraft of World War II, the B-29 was designed with state-of-the-art technology, which included a pressurized cabin, dual-wheeled tricycle landing gear, and an analog computer-controlled fire-control system that allowed one gunner and a fire-control officer to direct four remote machine gun turrets.
