Pierced Steel Planking
Marston Mat, more properly called pierced (or perforated) steel planking (PSP), is standardized, perforated steel matting material developed by the United States at the Waterways Experiment Station shortly before World War II, primarily for the rapid construction of temporary runways and landing strips (also misspelled as Marsden matting). The nickname came from Marston, North Carolina, adjacent to Camp Mackall airfield where the material was first used. Description Pierced steel planking (or pressed steel planking, named after the manufacturing process) consisted of steel strips with punched lightening holes in it. These holes were in rows, and a formation of ''U''-shaped channels between the holes. Hooks were formed along one long edge and slots along the other long edge so that adjacent mats could be connected. The short edges were cut straight with no holes or hooks. To achieve lengthwise interlocking, the mats were laid in a staggered pattern. The hooks were usually held i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aircrew Of No
Aircrew are personnel who operate an aircraft while in flight. The composition of a flight's crew depends on the type of aircraft, plus the flight's duration and purpose. Commercial aviation Flight deck positions In commercial aviation, the crew responsible for operating and controlling the aircraft are called ''flight crew''. Some flight crew position names are derived from nautical terms and indicate a rank or command structure similar to that on ocean-going vessels, allowing for quick executive decision making during normal operations or emergency situations. Historical Cockpit, flightdeck positions include: * Pilot in command, Captain, the Aircraft pilot, pilot Pilot-in-Command and highest-ranking member or members of a flight crew. * First officer (aviation), First officer (FO, also called a co-pilot), another pilot who is normally seated to the right of the captain. (On helicopters, an FO is normally seated to the left of the captain, who occupies the right-hand ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carolina Maneuvers
The Carolina Maneuvers were a series of United States Army exercises held around the border of North Carolina and South Carolina in 1941. The exercises, which involved some 350,000 troops, were designed to evaluate United States training, logistics, doctrine Doctrine (from , meaning 'teaching, instruction') is a codification (law), codification of beliefs or a body of teacher, teachings or instructions, taught principles or positions, as the essence of teachings in a given branch of knowledge or in a ..., and commanders.

Foreign Object Damage
In aviation and aerospace, the term foreign object damage (FOD) refers to any damage to an aircraft attributed to foreign object debris (also referred to as "FOD"), which is any particle or substance, alien to an aircraft or system which could potentially cause damage to it. External FOD hazards include bird strikes, hail, ice, sandstorms, ash-clouds or objects left on a runway or flight deck. Internal FOD hazards include items left in the cockpit that interfere with flight safety by getting tangled in control cables, jam moving parts or short-out electrical connections. To jet engines Jet engines can suffer major damage from even small objects being sucked into the engine. In the United States, the Federal Aviation Administration (FAA) requires that all engine types pass a test which includes firing a fresh chicken (dead, but not frozen) into a running jet engine from a small cannon. The engine does not have to remain functional after the test, but it must not cause signifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Douglas C-54 Skymaster
The Douglas C-54 Skymaster is a four-engined transport aircraft used by the United States Army Air Forces in World War II and the Korean War. Like the Douglas C-47 Skytrain derived from the DC-3, the C-54 Skymaster was derived from a civilian airliner, the Douglas DC-4. Besides transport of cargo, the C-54 also carried presidents, prime ministers, and military staff. Dozens of variants of the C-54 were employed in a wide variety of non-combat roles such as air-sea rescue, scientific and military research, and missile tracking and recovery. During the Berlin Airlift it hauled coal and food supplies to West Berlin. After the Korean War it continued to be used for military and civilian uses by more than 30 countries. It was one of the first aircraft to carry the President of the United States, the first being President Franklin D. Roosevelt during World War II. Design and development With the looming entry of the United States into World War II, in June 1941 the War Departm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tempelhof Airport
Berlin Tempelhof Airport () was one of the first airports in Berlin, Germany. Situated in the south-central Berlin borough of Tempelhof-Schöneberg, the airport ceased operating in 2008 amid controversy, leaving Tegel and Schönefeld as the two main airports serving the city for another twelve years until both were replaced by Berlin Brandenburg Airport in 2020. Tempelhof was designated as an airport by the Reich Ministry of Transport on 8 October 1923. The old terminal was originally constructed in 1927. In anticipation of increasing air traffic, the Nazi government began an enormous reconstruction in the mid-1930s. While it was occasionally cited as the world's oldest operating commercial airport, the title was disputed by several other airports, and is no longer an issue since its closure. Tempelhof was one of Europe's three iconic pre-World War II airports, the others being London's now defunct Croydon Airport and the old Paris–Le Bourget Airport. It acquired a furt ...

Berlin Airlift
The Berlin Blockade (24 June 1948 – 12 May 1949) was one of the first major international crises of the Cold War. During the multinational occupation of post–World War II Germany, the Soviet Union blocked the Western Allies' railway, road, and canal access to the sectors of Berlin under Western control. The Soviets offered to drop the blockade if the Western Allies withdrew the newly introduced Deutsche Mark from West Berlin. The Western Allies organised the Berlin Airlift (German: ''Berliner Luftbrücke'', lit. "Berlin Air Bridge") from 26 June 1948 to 30 September 1949 to carry supplies to the people of West Berlin, a difficult feat given the size of the city and the population. American and British air forces flew over Berlin more than 250,000 times, dropping necessities such as fuel and food, with the original plan being to lift 3,475 tons of supplies daily. By the spring of 1949, that number was often met twofold, with the peak daily delivery totalling 12,941 ton ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coral
Corals are colonial marine invertebrates within the subphylum Anthozoa of the phylum Cnidaria. They typically form compact Colony (biology), colonies of many identical individual polyp (zoology), polyps. Coral species include the important Coral reef, reef builders that inhabit tropical oceans and secrete calcium carbonate to form a hard skeleton. A coral "group" is a colony of very many cloning, genetically identical polyps. Each polyp is a sac-like animal typically only a few millimeters in diameter and a few centimeters in height. A set of tentacles surround a central mouth opening. Each polyp excretes an exoskeleton near the base. Over many generations, the colony thus creates a skeleton characteristic of the species which can measure up to several meters in size. Individual colonies grow by asexual reproduction of polyps. Corals also breed sexually by spawning: polyps of the same species release gametes simultaneously overnight, often around a full moon. Fertilized eggs form ...

Invasion Of Normandy
Operation Overlord was the codename for the Battle of Normandy, the Allied operation that launched the successful liberation of German-occupied Western Europe during World War II. The operation was launched on 6 June 1944 ( D-Day) with the Normandy landings (Operation Neptune). A 1,200-plane airborne assault preceded an amphibious assault involving more than 5,000 vessels. Nearly 160,000 troops crossed the English Channel on 6 June, and more than two million Allied troops were in France by the end of August. The decision to undertake cross-channel landings in 1944 was made at the Trident Conference in Washington in May 1943. American General Dwight D. Eisenhower was appointed commander of Supreme Headquarters Allied Expeditionary Force, and British General Bernard Montgomery was named commander of the 21st Army Group, which comprised all the land forces involved in the operation. The Normandy coast in northwestern France was chosen as the site of the landings, with the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
C-47 Skytrain
The Douglas C-47 Skytrain or Dakota ( RAF designation) is a military transport aircraft developed from the civilian Douglas DC-3 airliner. It was used extensively by the Allies during World War II. During the war the C-47 was used for troop transport, cargo, paratrooper, for towing gliders and military cargo parachute drops. The C-47 remained in front-line service with various military operators for many years.Parker 2013, pp. 13, 35, 37, 39, 45–47. It was produced in approximately triple the numbers as the larger, much heavier payload Curtiss C-46 Commando, which filled a similar role for the U.S. military. Approximately 100 countries' armed forces have operated the C-47 with over 60 variants of the aircraft produced. As with the civilian DC-3, the C-47 remains in service, over 80 years after the type's introduction. Design and development The C-47 differed from the civilian DC-3 by way of numerous modifications, including being fitted with a cargo door, hoist attach ...

Narsarsuaq
Narsarsuaq (lit. ''Great Plain'';''Facts and History of Narsarsuaq'', Narsarsuad Tourist Information old spelling: ''Narssarssuaq'') is a settlement in the Kujalleq municipality in southern Greenland. It had 123 inhabitants in 2020. There is a thriving tourism industry in and around Narsarsuaq, whose attractions include a great diversity of wildlife, gemstones, tours to glaciers, and an airfield museum.

Narsarsuaq Air Base
Bluie West One, later known as Narsarsuaq Air Base and Narsarsuaq Airport, was built on a glacial moraine at what is now the village of Narsarsuaq, near the southern tip of Greenland. Construction by the United States Army began in June 1941. The first aircraft landed there in January 1942, as a link in the North Atlantic air ferry route in World War II. The base had a peak population of about 4,000 American servicemen, and it is estimated that some 10,000 aircraft landed there en route to the war in Europe and North Africa. Soon after the United States entered the war, the War Department decided to deploy Major General Carl Spaatz's Eighth Air Force to Britain, putting the North Atlantic ferry route facilities constructed by the Corps to an early test. Radioing from Bluie West 1, while crossing the Atlantic in mid-June 1942, Spaatz ordered the movement to begin. The P-38 and P-39 fighters, piloted by combat crews who had been given special training in long-distance flying, were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
