CURV-III
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 is ...

Pisces Class DSV
''Pisces class submersibles'' are three person research deep-submergence vehicles designed and built by Hyco International Hydrodynamics of North Vancouver in British Columbia with a maximum operating depth of 2,000 m (6,560 ft). The vehicles have multiple view ports, sample collecting, environmental sensing, and instrument placement capabilities. The pressure hull has a inside diameter and is made of HY-100 steel with 3 forward-looking acrylic windows, in diameter. Designed by Allan Trice, the ''Pisces'' series of submersibles are representative of early crewed submersibles built in the late 1960s and were proven workhorses in offshore exploration and oceanographic research. ''Pisces II'' was the first production model of the design and was completed in 1968, with 9 more ''Pisces'' subs built before the manufacturer folded in the late 1970s. 1973 ''Pisces'' III rescue ''Pisces III'' was being used to bury cable and repeaters of the CANTAT-2 transatlantic telephone c ...

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 res ...

SS Edmund Fitzgerald
SS ''Edmund Fitzgerald'' was an American Great Lakes freighter that sank in Lake Superior during a storm on November 10, 1975, with the loss of the entire crew of 29 men. When launched on June 7, 1958, she was the largest ship on North America's Great Lakes, and she remains the largest to have sunk there. She was located in deep water on November 14, 1975, by a U.S. Navy aircraft detecting magnetic anomalies, and found soon afterwards to be in two large pieces. For 17 years, ''Edmund Fitzgerald'' carried taconite iron ore from mines near Duluth, Minnesota, to iron works in Detroit, Michigan; Toledo, Ohio; and other Great Lakes ports. As a workhorse, she set seasonal haul records six times, often breaking her own record. Captain Peter Pulcer was known for piping music day or night over the ship's intercom while passing through the St. Clair and Detroit rivers (between lakes Huron and Erie), and entertaining spectators at the Soo Locks (between Lakes Superior and Huron) ...

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 wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1966 Palomares B-52 Crash
The 1966 Palomares B-52 crash, also called the Palomares incident, occurred on 17 January 1966, when a B-52G bomber of the United States Air Force's Strategic Air Command collided with a KC-135 tanker during mid-air refueling at over the Mediterranean Sea, off the coast of Spain. The KC-135 was destroyed when its fuel load ignited, killing all four crew members. The B-52G broke apart, killing three of the seven crew members aboard. At the time of the accident, the B-52G was carrying four B28FI Mod 2 Y1 thermonuclear (hydrogen) bombs, all of which fell to the surface. Three were found on land near the small fishing village of Palomares in the municipality of Cuevas del Almanzora, Almería, Spain. The non-nuclear explosives in two of the weapons detonated upon impact with the ground, resulting in the contamination of a area with radioactive plutonium. The fourth, which fell into the Mediterranean Sea, was recovered intact after a search lasting two and a half months. Acci ...

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 ...
