Big Stink (B-29)
''Big Stink'' – later renamed ''Dave's Dream'' – was a United States Army Air Forces Boeing B-29-40-MO Superfortress bomber ( Victor number 90) that participated in the atomic bomb attack on Nagasaki, Japan on August 9, 1945. Assigned to the 393d Bomb Squadron, 509th Composite Group, it was used as a camera plane in support of the bomb-carrying B-29 '' Bockscar'' to photograph the explosion and effects of the bomb, and also to carry scientific observers. The mission was flown by crew C-14 but with Group Operations Officer Major James I. Hopkins, Jr., as the aircraft commander. Victor 90 left without one of the support members when Major Hopkins ordered Robert Serber of Project Alberta to leave the plane – reportedly after the B-29 had already taxied onto the runway – because the scientist had forgotten his parachute. Since Serber was the only crew member who knew how to operate the high-speed camera, Hopkins had to be instructed by radio from Tinian o ...

Bikini Atoll
Bikini Atoll ( or ; Marshallese: , , meaning "coconut place"), sometimes known as Eschscholtz Atoll between the 1800s and 1946 is a coral reef in the Marshall Islands consisting of 23 islands surrounding a central lagoon. After the Second World War, the atoll's inhabitants were forcibly relocated in 1946, after which the islands and lagoon were the site of 23 nuclear tests by the United States until 1958. The atoll is at the northern end of the Ralik Chain, approximately northwest of the capital Majuro. Three families were resettled on Bikini island in 1970, totaling about 100 residents, but scientists found dangerously high levels of strontium-90 in well water in May 1977, and the residents were carrying abnormally high concentrations of caesium-137 in their bodies. They were evacuated again in 1980. The atoll is occasionally visited today by divers and a few scientists, and is occupied by a handful of caretakers. Etymology The island's English name is derived from t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Great Artiste
''The Great Artiste'' was a U.S. Army Air Forces Silverplate B-29 bomber (B-29-40-MO 44-27353, Victor number 89), assigned to the 393d Bomb Squadron, 509th Composite Group. The aircraft was named for its bombardier, Captain Kermit Beahan, in reference to his bombing talents. It flew 12 training and practice missions in which it bombed Japanese-held Pacific islands and dropped pumpkin bombs on targets in Japan. It was the only aircraft to have participated in both the bombings of Hiroshima and Nagasaki, albeit as an observation aircraft on each mission. After the war ended it returned with the 509th Composite Group to Roswell Army Air Field, New Mexico. It was scrapped in September 1949 after being heavily damaged in an accident at Goose Bay Air Base, Labrador, the year before. Aircraft history Built at the Glenn L. Martin Aircraft Plant at Omaha, Nebraska, ''The Great Artiste '' (B-29-40-MO 44-27353) was a Silverplate B-29 Superfortress bomber. It was accepted by the Army ...

First Lieutenant
First lieutenant is a commissioned officer military rank in many armed forces; in some forces, it is an appointment. The rank of lieutenant has different meanings in different military formations, but in most forces it is sub-divided into a senior (first lieutenant) and junior (second lieutenant) rank. The NATO equivalent rank for land force officers is OF-1 rank. In navies, while certain rank insignia may carry the name lieutenant, the term may also be used to relate to a particular post or duty, rather than a rank. Indonesia In Indonesia, "first lieutenant" is known as ''Letnan Satu'' (''Lettu''), Indonesian National Armed Forces uses this rank across all three of its services. It is just above the rank of second lieutenant and just below the rank of captain. Israel In the Israel Defense Forces, the rank above second lieutenant is simply lieutenant.

Altimeter
An altimeter or an altitude meter is an instrument used to measure the altitude of an object above a fixed level. The measurement of altitude is called altimetry, which is related to the term bathymetry, the measurement of depth under water. The most common unit for altimeter calibration worldwide is hectopascals (hPa), except for North America (other than Canada ) and Japan where inches of mercury (inHg) are used. To obtain an accurate altitude reading in either feet or meters, the local barometric pressure must be calibrated correctly using the barometric formula. History The scientific principles behind the altimeter were first written by Alexander Bryce (minister), Rev. Alexander Bryce a Scottish minister and astronomer in 1772 who realised that the principles of a barometer could be adjusted to measure height. Pressure altimeter Altitude can be determined based on the measurement of atmospheric pressure. The greater the altitude, the lower the pressure. When a barometer is s ...

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 ...

Atomic Bomb
A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission (fission bomb) or a combination of fission and fusion reactions (thermonuclear bomb), producing a nuclear explosion. Both bomb types release large quantities of energy from relatively small amounts of matter. The first test of a fission ("atomic") bomb released an amount of energy approximately equal to . The first thermonuclear ("hydrogen") bomb test released energy approximately equal to . Nuclear bombs have had yields between 10 tons TNT (the W54) and 50 megatons for the Tsar Bomba (see TNT equivalent). A thermonuclear weapon weighing as little as can release energy equal to more than . A nuclear device no larger than a conventional bomb can devastate an entire city by blast, fire, and radiation. Since they are weapons of mass destruction, the proliferation of nuclear weapons is a focus of international relations policy. Nuclear weapons have been deployed ...

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 ...

Paul Tibbets
Paul Warfield Tibbets Jr. (23 February 1915 – 1 November 2007) was a brigadier general in the United States Air Force. He is best known as the aircraft captain who flew the B-29 Superfortress known as the '' Enola Gay'' (named after his mother) when it dropped a Little Boy, the first of two atomic bombs used in warfare, on the Japanese city of Hiroshima. Tibbets enlisted in the United States Army in 1937 and qualified as a pilot in 1938. After the Japanese attack on Pearl Harbor, he flew anti-submarine patrols over the Atlantic. In February 1942, he became the commanding officer of the 340th Bombardment Squadron of the 97th Bombardment Group, which was equipped with the Boeing B-17. In July 1942, the 97th became the first heavy bombardment group to be deployed as part of the Eighth Air Force, and Tibbets became deputy group commander. He flew the lead plane in the first American daylight heavy bomber mission against Occupied Europe on 17 August 1942, and the first American ...

Colonel
Colonel (abbreviated as Col., Col or COL) is a senior military officer rank used in many countries. It is also used in some police forces and paramilitary organizations. In the 17th, 18th and 19th centuries, a colonel was typically in charge of a regiment in an army. Modern usage varies greatly, and in some cases, the term is used as an honorific title that may have no direct relationship to military service. The rank of colonel is typically above the rank of lieutenant colonel. The rank above colonel is typically called brigadier, brigade general or brigadier general. In some smaller military forces, such as those of Monaco or the Vatican, colonel is the highest rank. Equivalent naval ranks may be called captain or ship-of-the-line captain. In the Commonwealth's air force ranking system, the equivalent rank is group captain. History and origins By the end of the late medieval period, a group of "companies" was referred to as a "column" of an army. According to Raymond Ol ...

North Field (Tinian)
North Field is a former World War II airfield on Tinian in the Mariana Islands. Abandoned after the war, today North Field is a tourist attraction. Along with several adjacent beaches on which Allied forces landed during the Battle of Tinian, the airfield is the major component of the National Historic Landmark District Tinian Landing Beaches, Ushi Point Field, Tinian Island. North Field was one of several bases for Twentieth Air Force Boeing B-29 Superfortress operations against the Japanese Home Islands in 1944–45. North Field contributed aircraft to the 1945 campaign to burn out Japanese cities with incendiary bombs, including the 9 March 1945 bombing of Tokyo which still stands as the most destructive air raid ever. North Field was the base for the 313th Bombardment Wing which carried out Operation Starvation, the dropping of naval mines in the harbors and sea lanes used by Japan. North Field was also the base for the 509th Composite Group which flew the atomic bombing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lieutenant Colonel
Lieutenant colonel ( , ) is a rank of commissioned officers in the armies, most marine forces and some air forces of the world, above a major and below a colonel. Several police forces in the United States use the rank of lieutenant colonel. The rank of lieutenant colonel is often shortened to simply "colonel" in conversation and in unofficial correspondence. Sometimes, the term 'half-colonel' is used in casual conversation in the British Army. In the United States Air Force, the term 'light bird' or 'light bird colonel' (as opposed to a 'full bird colonel') is an acceptable casual reference to the rank but is never used directly towards the rank holder. A lieutenant colonel is typically in charge of a battalion or regiment in the army. The following articles deal with the rank of lieutenant colonel: * Lieutenant-colonel (Canada) * Lieutenant colonel (Eastern Europe) * Lieutenant colonel (Turkey) * Lieutenant colonel (Sri Lanka) * Lieutenant colonel (United Kingdom) * L ...
