Laredo AFB
Laredo Air Force Base, is a since-deactivated Undergraduate Pilot Training (UPT) installation of the Air Training Command (ATC) in Laredo, Texas. The facility was originally established as Laredo Army Air Field, a World War II U.S. Army Air Force facility that began operations in November 1942, primarily as an aerial gunnery school with an associated gunnery range. The field became inactive in late 1945 and the property reverted to the city of Laredo, which used it as a municipal airport until 1950. That year, the base was reactivated and renamed Laredo Air Force Base in April 1952 to provide intermediate and advanced flight training for jet pilots, including pilot trainees from 24 countries. In the early 1960s, the Air Training Command transitioned to the Undergraduate Pilot Training (UPT) concept, where student pilots would take all flight training from basic through advanced at a single base. The initial host unit stationed at Laredo AFB was the 3640th Pilot Training Wing, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Concrete
Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. Concrete is the second-most-used substance in the world after water, and is the most widely used building material. Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminum combined. Globally, the ready-mix concrete industry, the largest segment of the concrete market, is projected to exceed $600 billion in revenue by 2025. This widespread use results in a number of environmental impacts. Most notably, the production process for cement produces large volumes of greenhouse gas emissions, leading to net 8% of global emissions. Other environmental concerns include widespread illegal sand mining, impacts on the surrounding environment such as increased surface runoff or urban heat island effect, and potential public health implications from toxic ingredients. Significant research and development is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
T-41 Mescalero
The Cessna T-41 Mescalero is a military version of the popular Cessna 172, operated by the United States Air Force and Army, as well as the armed forces of various other countries as a pilot-training aircraft. Design and development In 1964, the US Air Force (USAF) decided to use the off-the-shelf Cessna 172F as a lead-in aircraft for student pilots rather than starting them out in the T-37 jet aircraft. The USAF ordered 237 T-41As from Cessna. The first USAF class (67-A) of students began training on the T-41 from the civilian airport in Big Spring, Texas, in August 1965. The T-41B was the US Army version, with a Continental IO-360 engine and constant-speed propeller in place of the Continental O-300 and 7654 fixed-pitch propeller used in the 172 and the T-41A.Taylor, John: ''Jane's Pocket Book of Military Transport and Training Aircraft'', page 67.

Craig AFB
Craig Air Force Base near Selma, Alabama, was a U.S. Air Force undergraduate pilot training (UPT) installation that closed in 1977. Today the facility is a civilian airport known as Craig Field Airport and Industrial Complex (ICAO: KSEM; FAA: SEM). History World War II Originally built by the U.S. Army Air Force in 1940 to accommodate the growing number of flight trainees before World War II, Craig Field was one of the first training fields to offer single-engine training. Its first graduating class of 1941, the 39 cadets of Class 41D, completed the training course seven months before the United States' entry into World War II. The naming of the base was important to the nearby city of Selma, and several names were considered. The name finally chosen was to honor 1st Lt Bruce Kilpatrick Craig, who was killed when his B-24 crashed in June 1941. He was born in Selma and was initially commissioned as an officer in the Infantry Reserve prior to transferring to the Army Air Force an ...

Northrop T-38 Talon
The Northrop T-38 Talon is a two-seat, twinjet supersonic jet trainer. It was the world's first, and the most produced, supersonic trainer. The T-38 remains in service in several air forces. The United States Air Force (USAF) operates the most T-38s. In addition to training USAF pilots, the T-38 is used by NASA. The U.S. Naval Test Pilot School in Patuxent River, Maryland, is the principal US Navy operator (other T-38s were previously used as USN for dissimilar air combat training until replaced by the similar Northrop F-5 Tiger II). Pilots of other NATO nations fly the T-38 in joint training programs with USAF pilots. , the T-38 has been in service for over 60 years with its original operator, the United States Air Force. In September 2018, USAF announced the replacement of the Talon by the Boeing-Saab T-7 Red Hawk with phaseout to begin in 2023.

T-33
The Lockheed T-33 Shooting Star (or T-Bird) is an American subsonic jet trainer. It was produced by Lockheed and made its first flight in 1948. The T-33 was developed from the Lockheed P-80/F-80 starting as TP-80C/TF-80C in development, then designated T-33A. It was used by the U.S. Navy initially as TO-2, then TV-2, and after 1962, T-33B. The last operator of the T-33, the Bolivian Air Force, retired the type in July 2017, after 44 years of service. Design and development The T-33 was developed from the Lockheed P-80/F-80 by lengthening the fuselage by slightly more than 3 feet (1 m) and adding a second seat, instrumentation, and flight controls. It was initially designated as a variant of the P-80/F-80, the TP-80C/TF-80C. Design work on the Lockheed P-80 began in 1943, with the first flight on 8 January 1944. Following on the Bell P-59, the P-80 became the first jet fighter to enter full squadron service in the United States Army Air Forces. As more advanced jet ...

Asphalt
Asphalt, also known as bitumen (, ), is a sticky, black, highly viscous liquid or semi-solid form of petroleum. It may be found in natural deposits or may be a refined product, and is classed as a pitch. Before the 20th century, the term asphaltum was also used. Full text at Internet Archive (archive.org) The word is derived from the Ancient Greek ἄσφαλτος ''ásphaltos''. The largest natural deposit of asphalt in the world, estimated to contain 10 million tons, is the Pitch Lake located in La Brea in southwest Trinidad (Antilles island located on the northeastern coast of Venezuela), within the Siparia Regional Corporation. The primary use (70%) of asphalt is in Road surface, road construction, where it is used as the glue or binder mixed with construction aggregate, aggregate particles to create asphalt concrete. Its other main uses are for bituminous waterproofing products, including production of roofing felt and for sealing flat roofs. In material sciences an ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
