21st Airlift Squadron
The 21st Airlift Squadron is part of the 60th Air Mobility Wing at Travis Air Force Base, California. It operates C-17 Globemaster III aircraft carrying out United States Air Force global transport missions, duties which involve airlift and airdrop missions as well as provision of services and support in order to promote quality of life for both soldiers and civilians in situations requiring humanitarian aid. First formed as the 21st Transport Squadron at Archerfield Airport, Australia on 3 April 1942. Activated in the wake of the United States withdrawal from the Philippines, the squadron was formed with a mixture of personnel withdrawn from Clark Field and some reinforcements which had arrived in Australia but did not see combat in the Philippines. The squadron was hastily put together with some impressed civilian Douglas DC-2s and DC-3s.

C-17A Globemaster III
The McDonnell Douglas/Boeing C-17 Globemaster III is a large military transport aircraft developed for the United States Air Force (USAF) between the 1980s to the early 1990s by McDonnell Douglas. The C-17 carries forward the name of two previous piston-engined military cargo aircraft, the Douglas C-74 Globemaster and the Douglas C-124 Globemaster II. The C-17 is based upon the McDonnell Douglas YC-15, YC-15, a smaller prototype airlifter designed during the 1970s. It was designed to replace the Lockheed C-141 Starlifter, and also fulfill some of the duties of the Lockheed C-5 Galaxy. The redesigned airlifter differs from the YC-15 in that it is larger and has swept wings and more powerful engines. Development was protracted by a series of design issues, causing the company to incur a loss of nearly US$1.5 billion on the program's development phase. On 15 September 1991, roughly one year behind schedule, the first C-17 performed its maiden flight. The C-17 formally entered USAF ...

Paratroop
A paratrooper or military parachutist is a soldier trained to conduct military operations by parachuting directly into an area of operations, usually as part of a large airborne forces unit. Traditionally paratroopers fight only as light infantry armed with small arms and light weapons, although some paratroopers can also function as artillerymen or mechanized infantry by utilizing field guns, infantry fighting vehicles and light tanks that are often used in surprise attacks to seize strategic positions behind enemy lines such as airfields, bridges and major roads. Overview Paratroopers jump out of aircraft and use parachutes to land safely on the ground. This is one of the three types of "forced entry" strategic techniques for entering a theater (warfare), theater of war; the other two being by land and by water. Their tactical advantage of entering the battlefield from the air is that they can attack areas not directly accessible by other transport. The ability of airbo ...

Douglas B-18 Bolo
The Douglas B-18 Bolo is an American twin-engined medium bomber which served with the United States Army Air Corps and the Royal Canadian Air Force (as the Digby) during the late 1930s and early 1940s. The Bolo was developed by the Douglas Aircraft Company from their Douglas DC-2, DC-2 as a replacement for the Martin B-10. By 1940 standards, it was slow, had an inadequate defensive armament, and carried too small a bomb load. By 1942, surviving B-18s were relegated to antisubmarine, training and transport duties. A B-18 was one of the first USAAF aircraft to sink a German U-boat, on 22 August 1942 in the Caribbean. Design and development In 1934, the United States Army Air Corps requested for a twin-engine bomber with double the bomb load and range of the Martin B-10 then entering service. During the evaluation at Wright Field the following year, Douglas offered its DB-1. It was competing against the Boeing Model 299 (later developed into the Boeing B-17 Flying Fortress) and ...

Boeing B-17D Flying Fortress
The Boeing B-17 Flying Fortress is an American four-engined heavy bomber aircraft developed in the 1930s for the United States Army Air Corps (USAAC). A fast and high-flying bomber, the B-17 dropped more bombs than any other aircraft during World War II, used primarily in the European Theater of Operations. It is the third-most produced bomber in history, behind the American four-engined Consolidated B-24 Liberator and the German multirole, twin-engined Junkers Ju 88. The B-17 was also employed in transport, anti-submarine warfare, and search and rescue roles. In a USAAC competition, Boeing's prototype Model 299/XB-17 outperformed two other entries but crashed, losing the initial 200-bomber contract to the Douglas B-18 Bolo. Still, the Air Corps ordered 13 more B-17s for further evaluation, which were introduced into service in 1938. The B-17 evolved through numerous design advances but from its inception, the USAAC (from 1941 the United States Army Air Forces, USAAF) pro ...

Lockheed C-56 Lodestar
The Lockheed Model 18 Lodestar is an American passenger transport aircraft of the World War II era, developed as part of the Model 10 Electra family, specifically from the Lockheed Model 14 Super Electra. Design and development Sales of the 10–14 passenger Lockheed Model 14 Super Electra, which first flew in 1937, had proved disappointing, despite the aircraft's excellent performance. It was more expensive to operate than the larger Douglas DC-3, already in widespread use. In order to improve the type's economics, Lockheed decided to stretch the aircraft's fuselage by , allowing an extra two rows of seats to be fitted. The prototype for the revised airliner, designated Model 18 by Lockheed, was converted from the fourth Model 14, one of a batch which had been returned to the manufacturer by Northwest Airlines after a series of crashes. The modified aircraft first flew in this form on 21 September 1939, another two prototypes being converted from Model 14s, with the first new ...

Squadron (aviation)
A squadron in an air force, or naval or army aviation service, is a unit comprising a number of military aircraft and their aircrews, usually of the same type, typically with 12 to 24 aircraft, sometimes divided into three or four flights, depending on aircraft type and air force. In most armed forces, two or more squadrons will form a group or a wing. Some military forces (including the United States Air Force, United States Space Force, French Air and Space Force, Royal Air Force, German Air Force, Royal Netherlands Air Force, Belgian Air Component and Republic of Singapore Air Force) also use the term "squadron" for non-flying ground units (e.g. radar squadrons, missile squadrons, air defense squadrons, aircraft maintenance squadrons, security forces squadrons, civil engineering squadrons, range operations squadrons, range management squadrons, weather squadrons, medical squadrons, etc.).

DC-3
The Douglas DC-3 is a propeller-driven airliner manufactured by the Douglas Aircraft Company, which had a lasting effect on the airline industry in the 1930s to 1940s and World War II. It was developed as a larger, improved 14-bed sleeper version of the Douglas DC-2. It is a low-wing metal monoplane with conventional landing gear, powered by two radial piston engines of . Although the DC-3s originally built for civil service had the Wright R-1820 Cyclone, later civilian DC-3s used the Pratt & Whitney R-1830 Twin Wasp engine. The DC-3 has a cruising speed of , a capacity of 21 to 32 passengers or 6,000 lbs (2,700 kg) of cargo, and a range of , and can operate from short runways. The DC-3 had many exceptional qualities compared to previous aircraft. It was fast, had a good range, was more reliable, and carried passengers in greater comfort. Before World War II, it pioneered many air travel routes. It was able to cross the continental United States from New Y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Douglas DC-2
The Douglas DC-2 is a retired 14-passenger, twin-engined airliner that was produced by the American company Douglas Aircraft Company starting in 1934. It competed with the Boeing 247. In 1935, Douglas produced a larger version called the DC-3, which became one of the most successful aircraft in history. Design and development In the early 1930s, fears about the safety of wooden aircraft structures drove the US aviation industry to develop all-metal airliners. United Airlines had exclusive right to the all metal twin-engine Boeing 247; rival TWA issued a specification for an all-metal trimotor. The Douglas response was more radical. When it flew on July 1, 1933, the prototype DC-1 had a robust tapered wing, retractable landing gear, and two 690 hp (515 kW) Wright radial engines driving variable-pitch propellers. It seated 12 passengers. The DC-2 was longer than the DC-1, had more powerful engines, and carried 14 passengers in a 66-inch-wide cabin. Douglas test ...
