BAe Dunsfold
Dunsfold Aerodrome (former ICAO code EGTD) is an unlicensed airfield in Surrey, England, near the village of Cranleigh. It extends across land in the villages of Dunsfold and Alfold. It was built by the Canadian Army and civilian contractors as a Class A bomber airfield for Army Co-operation Command. It was commanded by the Royal Canadian Air Force from 1942 to 1944 and was known as Royal Canadian Air Force Station Dunsfold. Under RAF control it was RAF Dunsfold. Post-war it was used by Hawker Siddeley and then its successor British Aerospace. From 2002 to 2020, it was used as the main site of the BBC show ''Top Gear''. History Construction and military use Canadian engineers were charged with the construction of the aerodrome. Such projects had previously taken up to a year to complete and this site was complicated by the two hundred acres of woodland that first had to be cleared. The Canadian sappers had access to large-scale earth moving equipment from North America o ... [...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] |
430 Tactical Helicopter Squadron
430 Tactical Helicopter Squadron is a unit of the Canadian Forces under the Royal Canadian Air Force. It operates Bell CH-146 Griffons from CFB Valcartier, near Quebec City in Quebec, Canada. History No. 430 Squadron RCAF was a unit of the Royal Canadian Air Force formed during World War II as the "City of Sudbury" squadron in 1943. Initially created as an army co-operation squadron, 430 was redesignated as a fighter reconnaissance unit later that year. The unit was stationed in England, France, Belgium, the Netherlands, and Germany, and flew photo reconnaissance missions in support of planning for the Normandy landings. After D-Day, missions included before-and-after photography of attacks on V-1 flying bomb launch sites and support for ground forces. 430 Squadron was disbanded in Germany in August 1945.430 T ...

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 Department t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Avro Lancastrian
The Avro 691 Lancastrian was a Canadian and British passenger and mail transport aircraft of the 1940s and 1950s developed from the Avro Lancaster heavy bomber. The Lancaster was named after Lancaster, Lancashire; a Lancastrian is an inhabitant of Lancashire. The Lancastrian was basically a modified Lancaster bomber without armour or armament and with the gun turrets replaced by streamlined metal fairings, including a new nose section. The initial batch was converted directly from Lancasters; later batches were new builds. Design and development In 1943, Canada's Victory Aircraft converted a Lancaster X bomber for civilian transport duties with Trans-Canada Airlines (TCA). (After the war Victory Aircraft was purchased by what became Avro Canada). This conversion was a success, resulting in eight additional Lancaster Xs being converted. The "specials" were powered by Packard-built Merlin 38 engines and featured a lengthened, streamlined nose and tail cone. Range was incre ...

Avro York
The Avro York was a British transport aircraft developed by Avro during the Second World War. The design was derived from the Avro Lancaster heavy bomber, several sections of the York and Lancaster being identical. Due to the importance of Lancaster production, York output proceeded slowly until 1944, after which a higher priority was placed upon transport aircraft. The York saw service in military and civilian roles with various operators between 1943 and 1964. In civilian service, British South American Airways (BSAA) and British Overseas Airways Corporation (BOAC) were the largest users of the type. In military service, large numbers of Yorks were used for air-supply missions during the Berlin Blockade 1948–49. A number of the type were used as air transports of heads of state and government; VIPs who flew on Yorks included British Prime Minister Winston Churchill, French General Charles de Gaulle, Indian Governor-General Lord Mountbatten and South African Prime Min ...

Prisoners Of War
A prisoner of war (POW) is a person who is held Captivity, captive by a belligerent power during or immediately after an armed conflict. The earliest recorded usage of the phrase "prisoner of war" dates back to 1610. Belligerents hold prisoners of war in custody for a range of legitimate and illegitimate reasons, such as isolating them from the enemy combatants still in the field (releasing and Repatriation, repatriating them in an orderly manner after hostilities), demonstrating military victory, punishing them, prosecuting them for war crimes, exploitation of labour, exploiting them for their labour, recruiting or even Conscription, conscripting them as their own combatants, collecting military and political intelligence from them, or Indoctrination, indoctrinating them in new political or religious beliefs. Ancient times For most of human history, depending on the culture of the victors, enemy fighters on the losing side in a battle who had surrendered and been taken as ...

Hawker Tempest
The Hawker Tempest is a British fighter aircraft that was primarily used by the Royal Air Force (RAF) in the Second World War. The Tempest, originally known as the ''Typhoon II'', was an improved derivative of the Hawker Typhoon, intended to address the Typhoon's unexpected deterioration in performance at high altitude by replacing its wing with a thinner laminar flow design. Since it had diverged considerably from the Typhoon, it was renamed ''Tempest''. The Tempest emerged as one of the most powerful fighters of World War II and at low altitude was the fastest single-engine propeller-driven aircraft of the war. Upon entering service in 1944, the Tempest performed low-level interception, particularly against the V-1 flying bomb threat, and ground attack supporting major invasions like Operation Market Garden. Later, it successfully targeted the rail infrastructure in Germany and ''Luftwaffe'' aircraft on the ground, as well as countering similar attacks by German fighters. T ...

Hawker Typhoon
The Hawker Typhoon is a British single-seat fighter-bomber, produced by Hawker Aircraft. It was intended to be a medium-high altitude interceptor, as a replacement for the Hawker Hurricane, but several design problems were encountered and it never completely satisfied this requirement.Thomas and Shores 1988, p. 16. The Typhoon was originally designed to mount twelve .303 inch (7.7 mm) Browning machine guns and be powered by the latest engines. Its service introduction in mid-1941 was plagued with problems and for several months the aircraft faced a doubtful future. When the ''Luftwaffe'' brought the new Focke-Wulf Fw 190 into service in 1941, the Typhoon was the only RAF fighter capable of catching it at low altitudes; as a result it secured a new role as a low-altitude interceptor. The Typhoon became established in roles such as night-time intruder and long-range fighter. From late 1942 the Typhoon was equipped with bombs and from late 1943 RP-3 rockets were added to i ...

Supermarine Spitfire
The Supermarine Spitfire is a British single-seat fighter aircraft used by the Royal Air Force and other Allied countries before, during, and after World War II. Many variants of the Spitfire were built, from the Mk 1 to the Rolls-Royce Griffon engined Mk 24 using several wing configurations and guns. It was the only British fighter produced continuously throughout the war. The Spitfire remains popular among enthusiasts; around 70 remain airworthy, and many more are static exhibits in aviation museums throughout the world. The Spitfire was designed as a short-range, high-performance interceptor aircraft by R. J. Mitchell, chief designer at Supermarine Aviation Works, which operated as a subsidiary of Vickers-Armstrong from 1928. Mitchell developed the Spitfire's distinctive elliptical wing with innovative sunken rivets (designed by Beverley Shenstone) to have the thinnest possible cross-section, achieving a potential top speed greater than that of several contemporary figh ...

Netherlands Naval Aviation Service
The Netherlands Naval Aviation Service ( nl, Marineluchtvaartdienst, shortened to MLD) is the naval aviation branch of the Royal Netherlands Navy. History World War I Although the MLD was formed in 1914, with the building of a seaplane base at De Mok, Texel, it developed slowly in the inter-war years due to limited budget. After the graduation of the first pilot group in 1915, on August 18, 1917, the MLD was founded under official decree and De Mok became the main base. At this time, the emphasis was on seaplane operations in the Dutch East Indies where Dornier Wal aircraft enabled patrols of the large archipelago in 1926. The perceived threat from Nazi Germany in the 1930s accelerated the development of air capability and the purchase of new equipment. World War II The German invasion of the Netherlands on May 10, 1940, rapidly overwhelmed Dutch resistance and the MLD aircraft were redeployed to France before the Dutch formally surrendered on 15 May. Shortly after, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medium Bomber
A medium bomber is a military bomber Fixed-wing aircraft, aircraft designed to operate with medium-sized Aerial bomb, bombloads over medium Range (aeronautics), range distances; the name serves to distinguish this type from larger heavy bombers and smaller light bombers. Mediums generally carried about two tons of bombs, compared to light bombers that carried one ton, and heavies that carried four or more. The term was used prior to and during World War II, based on available parameters of Aircraft engine, engine and Aerospace engineering, aeronautical technology for bomber aircraft designs at that time. After the war, medium bombers were replaced in world air forces by more advanced and capable aircraft. History In the early 1930s many air forces were looking to modernize their existing bomber aircraft fleets, which frequently consisted of older biplanes. The new designs were typically twin-engined monoplanes, often of all-metal construction, and optimized for high enough pe ...
