Tinian
Tinian ( or ; old Japanese name: 天仁安島, ''Tenian-shima'') is one of the three principal islands of the Commonwealth of the Northern Mariana Islands. Together with uninhabited neighboring Aguiguan, it forms Tinian Municipality, one of the four constituent municipalities of the Northern Marianas. Tinian's largest village is San Jose. History Spanish colonial period Tinian, together with Saipan, was possibly first sighted by Europeans of the Spanish expedition of Ferdinand Magellan, when it made landfall in the southern Marianas on 6 March 1521. It was likely sighted next by Gonzalo Gómez de Espinosa in 1522 on board the Spanish ship ''Trinidad'', in an attempt to reach Panama after the death of Magellan. This would have happened after the sighting of the Maug Islands in between the end of August and end of September. Gonzalo de Vigo deserted in the Maugs from the ''Trinidad'' and in the next four years, living with the Chamorros, visited thirteen main islands in the ...

Boeing B-29 Superfortress
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. The $3 billion cost of design and production (equivalent to $ billion today), far exceeding the $1.9 b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Little Boy
"Little Boy" was the type of atomic bomb dropped on the Japanese city of Hiroshima on 6 August 1945 during World War II, making it the first nuclear weapon used in warfare. The bomb was dropped by the Boeing B-29 Superfortress ''Enola Gay'' piloted by Colonel Paul W. Tibbets, Jr., commander of the 509th Composite Group of the United States Army Air Forces and Captain Robert A. Lewis. It exploded with an energy of approximately and caused widespread death and destruction throughout the city. The Hiroshima bombing was the second man-made nuclear explosion in history, after the Trinity nuclear test. Little Boy was developed by Lieutenant Commander Francis Birch (geophysicist), Francis Birch's group at the Manhattan Project's Los Alamos Laboratory during World War II, a reworking of their unsuccessful Thin Man (nuclear bomb), Thin Man nuclear bomb. Like Thin Man, it was a gun-type fission weapon, but it derived its explosive power from the nuclear fission of uranium-235, where ...

William Sterling Parsons
Rear Admiral William Sterling "Deak" Parsons (26 November 1901 – 5 December 1953) was an American naval officer who worked as an ordnance expert on the Manhattan Project during World War II. He is best known for being the weaponeer on the ''Enola Gay'', the aircraft which dropped the Little Boy atomic bomb on Hiroshima, Japan in 1945. To avoid the possibility of a nuclear explosion if the aircraft crashed and burned on takeoff, he decided to arm the bomb in flight. While the aircraft was ''en route'' to Hiroshima, Parsons climbed into the cramped and dark bomb bay, and inserted the powder charge and detonator. He was awarded the Silver Star for his part in the mission. A 1922 graduate of the United States Naval Academy, Parsons served on a variety of warships beginning with the battleship . He was trained in ordnance and studied ballistics under L.T.E. Thompson at the Naval Proving Ground in Dahlgren, Virginia. In July 1933, Parsons became liaison officer between the Bureau ...

Captain (United States)
In the United States uniformed services, captain is a commissioned-officer rank. In keeping with the traditions of the militaries of most nations, the rank varies between the services, being a senior rank in the naval services and a junior rank in the ground and air forces. Many fire departments and police departments in the United States also use the rank of captain as an officer in a specific unit. Usage For the naval rank, a captain is a senior officer of U.S. uniformed services pay grades O-6 (the sixth officer rank), typically commanding seagoing vessels, major aviation commands and shore installations. This rank is used by the U.S. Navy, U.S. Coast Guard, U.S. Public Health Service Commissioned Corps, the National Oceanic and Atmospheric Administration Commissioned Corps, and the U.S. Maritime Service. Seaborne services of the United States and many other nations refer to the officer in charge of any seagoing vessel as "captain" regardless of actual rank. For instance ...

Wendover Air Force Base
Wendover Air Force Base is a former United States Air Force base in Utah now known as Wendover Airport. During World War II, it was a training base for B-17 and B-24 bomber crews. It was the training site of the 509th Composite Group, the B-29 unit that carried out the atomic bombings of Hiroshima and Nagasaki. After the war, Wendover was used for training exercises, gunnery range and as a research facility. It was closed by the Air Force in 1969, and the base was given to Wendover City in 1977. Tooele County, Utah, assumed ownership of the airport and base buildings in 1998, and the County continues to operate the airfield as a public airport. A portion of the original bombing range is now the Utah Test and Training Range (UTTR) which is used extensively by the Air Force with live fire targets on the range. Origins Wendover Air Force Base's history began in 1940, when the United States Army began looking for additional bombing ranges. The area near the town of Wendover was ...

Los Alamos National Laboratory
Los Alamos National Laboratory (often shortened as Los Alamos and LANL) is one of the sixteen research and development laboratories of the United States Department of Energy (DOE), located a short distance northwest of Santa Fe, New Mexico, in the American southwest. Best known for its central role in helping develop the first atomic bomb, LANL is one of the world's largest and most advanced scientific institutions. Los Alamos was established in 1943 as Project Y, a top-secret site for designing nuclear weapons under the Manhattan Project during World War II.The site was variously called Los Alamos Laboratory and Los Alamos Scientific Laboratory. Chosen for its remote yet relatively accessible location, it served as the main hub for conducting and coordinating nuclear research, bringing together some of the world's most famous scientists, among them numerous Nobel Prize winners. The town of Los Alamos, directly north of the lab, grew extensively through this period. After ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
