CURV-III PISCES RESCUE - NAVY PHOTO 1973
CURV-III was the fourth generation of the United States Navy Cable-controlled Undersea Recovery Vehicle (CURV). CURV was a prototype for remotely operated underwater vehicles and a pioneer for teleoperation. It became famous in 1966 when CURV-I was used to recover a hydrogen bomb from the floor of the Mediterranean Sea. In 1973, CURV-III performed the deepest underwater rescue in history when it rescued two men from the ocean surface who were stranded 76 hours in the submersible ''Pisces III'' with just minutes of air remaining. The CURV-III became known in the Great Lakes region in 1976 when it was used to survey the wreck of the SS ''Edmund Fitzgerald''. CURV-21 is the current generation that replaced CURV-III. History CURV was developed by Naval Ordnance Test Station, Pasadena, California, US in the early 1960s. It was initially designed to recover test ordnance lost off San Clemente Island at depths as great as . CURV was the pioneer for teleoperation. CURV-III i ...

Altimeter
An altimeter or an altitude meter is an instrument used to measure the altitude of an object above a fixed level. The measurement of altitude is called altimetry, which is related to the term bathymetry, the measurement of depth under water. The most common unit for altimeter calibration worldwide is hectopascals (hPa), except for North America (other than Canada ) and Japan where inches of mercury (inHg) are used. To obtain an accurate altitude reading in either feet or meters, the local barometric pressure must be calibrated correctly using the barometric formula. History The scientific principles behind the altimeter were first written by Rev. Alexander Bryce a Scottish minister and astronomer in 1772 who realised that the principles of a barometer could be adjusted to measure height. Pressure altimeter Altitude can be determined based on the measurement of atmospheric pressure. The greater the altitude, the lower the pressure. When a barometer is supplied with a nonlinear ...

Rescue Of Roger Mallinson And Roger Chapman
The rescue of Roger Mallinson and Roger Chapman occurred between 29 August and 1 September 1973 after their Vickers Oceanics small submersible ''Pisces III'' was trapped on the seabed at a depth of , off Ireland in the Celtic Sea. The 76-hour multinational rescue effort resulted in the deepest sub rescue in history. Submersible and the crew The Canadian commercial submersible ''Pisces III'' measured long by wide by high. It was built by International Hydrodynamics of North Vancouver, British Columbia, and had been launched in 1969. ''Pisces III'' originally had tail fins, which were removed to improve access and handling when the submersible was purchased by Vickers Oceanics. Ironically, if the fins had been retained they would have prevented the entanglement of the towline on the craft's machinery sphere which caused the 1973 accident. ''Pisces III'' had sunk once before, during trials in Vancouver Bay in 1971. Peter Messervy of Vickers Oceanics, who would lead the re ...

Transatlantic Telephone Cable
A transatlantic telecommunications cable is a submarine communications cable connecting one side of the Atlantic Ocean to the other. In the 19th and early 20th centuries, each cable was a single wire. After mid-century, coaxial cable came into use, with amplifiers. Late in the 20th century, all cables installed used optical fiber as well as optical amplifiers, because distances range thousands of kilometers. History When the first transatlantic telegraph cable was laid in 1858 by Cyrus West Field, it operated for only three weeks; subsequent attempts in 1865 and 1866 were more successful. In July 1866 '' Great Eastern'' sailed out of Valentia Island, Ireland and on July 26th landed at Hearts Content in Newfoundland. It was active until 1965. Although a telephone cable was discussed starting in the 1920s, to be practical it needed a number of technological advances which did not arrive until the 1940s. Starting in 1927, transatlantic telephone service was radio-based. TAT-1 (Tra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Invention & Technology Magazine
''Invention & Technology Magazine'' (formerly known as ''American Heritage of Invention & Technology'') is a quarterly magazine dedicated to the history of technology. It was launched with sponsorship from General Motors in the summer of 1985 as a spinoff of ''American Heritage'' magazine. Later, the magazine had a partnership with the National Inventors Hall of Fame. “Our subject matter is actually nothing less than the making of the world we live in, and the stories of all the extraordinary people who made it,” wrote Frederick Allen, the Founding Editor, in 1985. He noted that the field of the history of technology is relatively new. "Up to now there has been no general magazine of wide circulation reporting on it. A gap exists between the findings of the scholars and the educated public," he wrote. There were three issues of the magazine a year until 1992, when it became quarterly. Following the Summer 2007 issue (volume 23, number 1), publication was suspended (along with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grappling Hook
A grappling hook or grapnel is a device that typically has multiple hooks (known as ''claws'' or ''flukes'') attached to a rope; it is thrown, dropped, sunk, projected, or fastened directly by hand to where at least one hook may catch and hold onto objects. Generally, grappling hooks are used to temporarily secure one end of a rope. They may also be used to dredge for submerged objects. The device was invented by the Romans in approximately 260 BC. The grappling hook was originally used in naval warfare to catch ship rigging so that it could be boarded. Design A common design has a central shaft with a hole ("eye") at the shaft base to attach the rope, and three or four equally spaced hooks at the end, arranged so that at least one is likely to catch on some protuberance of the target. Some modern designs feature folding hooks to resist unwanted attachment. Most grappling hooks are thrown by hand, but some used in rescue work are propelled by compressed air (e.g., the Plu ...

DSV Alvin
''Alvin'' (DSV-2) is a crewed deep-ocean research submersible owned by the United States Navy and operated by the Woods Hole Oceanographic Institution (WHOI) in Woods Hole, Massachusetts. The vehicle was built by General Mills' Electronics Group in Minneapolis, Minnesota. Named to honor the prime mover and creative inspiration for the vehicle, Allyn Vine, ''Alvin'' was commissioned on 5 June 1964. The submersible is launched from the deep submergence support vessel , which is also owned by the U.S. Navy and operated by WHOI. The submersible has made more than 5,000 dives, carrying two scientists and a pilot, to observe the lifeforms that must cope with super-pressures and move about in total darkness, as well as exploring the wreck of ''Titanic''. Research conducted by ''Alvin'' has been featured in nearly 2,000 scientific papers. Design ''Alvin'' was designed as a replacement for bathyscaphes and other less maneuverable oceanographic vehicles. Its more nimble design was made ...

Palomares, Almería
Palomares is an agricultural, fishing, and tourist town along the Mediterranean Sea in the Almería province of Andalusia, Spain. It is about above sea level. The village falls within the municipality of Cuevas del Almanzora. The ruins of ''El Artial'' lie just outside the village. Crashes of a B-52 and a KC-135 in 1966 The town is noted for a fatal accident in 1966 in which a B-52 Stratofortress of the Strategic Air Command crashed after a midair collision with a KC-135 Stratotanker plane, causing radioactive contamination after its payload of four hydrogen bombs (H-bombs) was dispersed and crashed. There were four thermonuclear weapons in the bomber. The high-explosive igniters in two of these bombs detonated on impact, spreading radioactive material, including deadly plutonium-239, over a wide area of the Spanish countryside, but safety mechanisms and electronics prevented nuclear explosions. The third H-bomb landed via parachute into a stream, where it was relatively in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boeing KC-135 Stratotanker
The Boeing KC-135 Stratotanker is an American military aerial refueling aircraft that was developed from the Boeing 367-80 prototype, alongside the Boeing 707 airliner. It is the predominant variant of the C-135 Stratolifter family of transport aircraft. The KC-135 was the United States Air Force's first jet-powered refueling tanker and replaced the KC-97 Stratofreighter. The KC-135 was initially tasked with refueling strategic bombers, but it was used extensively in the Vietnam War and later conflicts such as Operation Desert Storm to extend the range and endurance of US tactical fighters and bombers. The KC-135 entered service with the United States Air Force (USAF) in 1957; it is one of nine military fixed-wing aircraft with over 60 years of continuous service with its original operator. The KC-135 is supplemented by the larger McDonnell Douglas KC-10 Extender. Studies have concluded that many of the aircraft could be flown until 2030, although maintenance costs have great ...
