The NorthropB-2 Spirit, also known as the Stealth Bomber, is an American heavy strategic bomber, featuring low observable stealth technology designed for penetrating dense anti-aircraft defenses; it is a flying wing design with a crew of two. The bomber can deploy both conventional and thermonuclear weapons, such as up to eighty 500-pound class (230 kg) Mk 82 JDAM Global Positioning System-guided bombs, or sixteen 2,400-pound (1,100 kg) B83 nuclear bombs. The B-2 is the only acknowledged aircraft that can carry large air-to-surface standoff weapons in a stealth configuration.
Laika was a Soviet space dog who became one of the first animals in space, and the first animal to orbit the Earth. Laika, a stray mongrel from the streets of Moscow, was selected to be the occupant of the Soviet spacecraft Sputnik 2 that was launched into outer space on 3 November 1957.
Prairie dogs are herbivorous burrowing rodents native to the grasslands of North America. The five species are: black-tailed, white-tailed, Gunnison's, Utah, and Mexican prairie dogs. They are a type of ground squirrel, found in the United States, Canadian Prairies and Mexico. In Mexico, prairie dogs are found primarily in the northern states, which lie at the southern end of the Great Plains: northeastern Sonora, north and northeastern Chihuahua, northern Coahuila, northern Nuevo León, and northern Tamaulipas. In the United States, they range primarily to the west of the Mississippi River, though they have also been introduced in a few eastern locales. Despite the name, they are not actually canines.
The Siberian Husky is a medium size working dog breed. The breed belongs to the Spitz genetic family. It is recognizable by its thickly furred double coat, erect triangular ears, and distinctive markings, and is smaller than a very similar-looking dog, the Alaskan Malamute.
The Labrador Retriever, or just Labrador, is a large type of retriever-gun dog. The Labrador is one of the most popular breeds of dog in Canada, the United Kingdom and the United States.
The German Shepherd is a breed of medium to big-sized working dog that originated in Germany. In the English language, the breed's officially recognized name is German Shepherd Dog. The breed was officially known as the Alsatian in Britain from after the First World War until 1977 when its name was changed back to German Shepherd. Despite its primitive, wolf-like appearance the German Shepherd is a relatively modern breed of dog, with their origin dating to 1899. As part of the Herding Group, German Shepherds are working dogs developed originally for herding sheep. Since that time however, because of their strength, intelligence, trainability, and obedience, German Shepherds around the world are often the preferred breed for many types of work, including disability assistance, search-and-rescue, police and military roles, and acting. The German Shepherd is the second-most registered breed by the American Kennel Club and seventh-most registered breed by The Kennel Club in the United Kingdom.
The Airbus A320 family consists of short- to medium-range, narrow-body, commercial passenger twin-engine jet airliners by Airbus. The family includes the A318, A319, A320 and A321, as well as the ACJ business jet. The A320s are also named A320ceo following the introduction of the A320neo. The aircraft family can accommodate up to 236 passengers and has a range of 3,100 to 12,000 km, depending on model.
The Dam Busters is a 1955 British epic war film starring Richard Todd and Michael Redgrave. It was directed by Michael Anderson. The film recreates the true story of Operation Chastise when in 1943 the RAF's 617 Squadron attacked the Möhne, Eder, and Sorpe dams in Nazi Germany with Barnes Wallis's bouncing bomb.
The Jack Russell Terrier is a small terrier that has its origins in fox hunting in England. It is principally white-bodied and smooth, rough or broken-coated and can be any colour.
The Cessna L-19/O-1 Bird Dog was a liaison and observation aircraft. It was the first all-metal fixed-wing aircraft ordered for and by the United States Army following the Army Air Forces' separation from it in 1947. The Bird Dog had a lengthy career in the U.S. military, as well as in other countries.
The Boeing AGM-69 SRAM was a nuclear air-to-surface missile. It had a range of up to 50 nautical miles, and was intended to allow US Air Force strategic bombers to penetrate Soviet airspace through the neutralization of surface-to-air missile defenses.
The PDSA Dickin Medal was instituted in 1943 in the United Kingdom by Maria Dickin to honour the work of animals in World War II. It is a bronze medallion, bearing the words "For Gallantry" and "We Also Serve" within a laurel wreath, carried on a ribbon of striped green, dark brown, and pale blue. It is awarded to animals that have displayed "conspicuous gallantry or devotion to duty while serving or associated with any branch of the Armed Forces or Civil Defence Units". The award is commonly referred to as "the animals' Victoria Cross".
The North American Aviation AGM-28 Hound Dog was a supersonic, turbojet-propelled, air-launched cruise missile developed in 1959 for the United States Air Force. It was primarily designed to be capable of attacking Soviet ground-based air defense sites prior to a potential air attack by B-52 Stratofortress long range bombers during the Cold War. The Hound Dog was first given the designation B-77, then redesignated GAM-77, and finally as AGM-28. It was conceived as a temporary standoff missile for the B-52, to be used until the GAM-87 Skybolt air-launched ballistic missile was available. Instead, the Skybolt was cancelled within a few years and the Hound Dog continued to be deployed for a total of 15 years until its replacement by newer missiles, including the AGM-69 SRAM and then the AGM-86 ALCM.
The Pratt & Whitney J52 is an axial-flow dual-spool turbojet engine originally designed for the United States Navy, in the 40 kN class. It powered the A-6 Intruder and the AGM-28 Hound Dog cruise missile. The engine is still in use in 2017 in models of the A-4 Skyhawk and the EA-6B Prowler.
A dog-leg is a configuration of stairs between two floors of a building, often a domestic building, in which a flight of stairs ascends to a half-landing before turning at a right angle and continuing upwards. The flights do not have to be equal, and frequently are not.
The domestic dog is a member of the genus Canis (canines), which forms part of the wolf-like canids, and is the most widely abundant terrestrial carnivore. The dog and the extant gray wolf are sister taxa as modern wolves are not closely related to the wolves that were first domesticated, which implies that the direct ancestor of the dog is extinct. The dog was the first species to be domesticated and has been selectively bred over millennia for various behaviors, sensory capabilities, and physical attributes.
The Grand National Teams (GNT) national bridge championship is held at the summer American Contract Bridge League (ACBL) North American Bridge Championship (NABC).
The Boeing B-52 Stratofortress is an American long-range, subsonic, jet-powered strategic bomber. The B-52 was designed and built by Boeing, which has continued to provide support and upgrades. It has been operated by the United States Air Force (USAF) since the 1950s. The bomber is capable of carrying up to 70,000 pounds (32,000 kg) of weapons, and has a typical combat range of more than 8,800 miles (14,080 km) without aerial refueling.
