RV Le Suroît
RV ''Le Suroît'' is a French research vessel operated by IFREMER. In 1985, it was involved in the successful Franco-American expedition to find the wreck of the RMS Titanic, wreck of the RMS ''Titanic''. Since being refurbished in 1999, the vessel is able to undertake bathymetric and seismology, seismic research, as well as Core sample, coring, dredging, and trawling tasks. History The vessel was commissioned and built in 1975 by Ateliers et Chantiers de Manche, la Manche in Dieppe, Seine-Maritime. In 1985, the ship was equipped with the new ''System Acoustique Remorqué'' (SAR) sonar device. In early summer, the vessel undertook a 10-day sonar mission in an attempt to find the wreckage of RMS Titanic, RMS ''Titanic''. Aboard ''Le Suroît'' on this mission was Robert Ballard. ''Le Suroît'' was able to rule out large sections of a pre-determined search area – between 26 July and 6 August, 80% of the area had been searched. It later transpired that on one of its fir ...

Concarneau
Concarneau (, meaning ''Bay of Cornouaille'') is a commune in the Finistère department of Brittany in north-western France. Concarneau is bordered to the west by the Baie de La Forêt. The town has two distinct areas: the modern town on the mainland and the medieval Ville Close, a walled town on a long island in the centre of the harbour. Historically, the old town was a centre of shipbuilding, and its ramparts date from the 14th century. The Ville Close is now devoted to tourism with many restaurants and shops aimed at tourists. However restraint has been shown in resisting the worst excesses of souvenir shops. Also in the Ville Close is the fishing museum. The Ville Close is connected to the town by a bridge and at the other end a ferry to the village of Lanriec on the other side of the harbour. Events In August the town holds the annual ''Fête des Filets Bleus'' (Festival of the blue nets). The festival, named after the traditional blue nets of Concarneau's fishing fleet, is ...

1974 Ships
Major events in 1974 include the aftermath of the 1973 oil crisis and the resignation of United States President Richard Nixon following the Watergate scandal. In the Middle East, the aftermath of the 1973 Yom Kippur War determined politics; following Israeli Prime Minister Golda Meir's resignation in response to high Israeli casualties, she was succeeded by Yitzhak Rabin. In Europe, the invasion and occupation of northern Cyprus by Turkish troops initiated the Cyprus dispute, the Carnation Revolution took place in Portugal, and Chancellor of West Germany Willy Brandt resigned following an espionage scandal surrounding his secretary Günter Guillaume.

Cruising Speed
Cruise is the phase of aircraft flight that starts when the aircraft levels off after a climb, until it begins to descend for landing. Cruising usually consumes the majority of a flight, and it may include changes in heading (direction of flight), airspeed and altitude. Commercial or passenger aircraft are usually designed for optimum performance around their cruise speed ( VC) and cruise altitude. Factors affecting optimum cruise speed and altitude include payload, center of gravity, air temperature, and humidity. Cruise altitude is usually where the higher ground speed is balanced against the decrease in engine thrust and efficiency at higher altitudes. A typical cruising airspeed for a long-distance commercial passenger aircraft is approximately . The typical cruising altitude for commercial airliners is . The speed which covers the greatest distance for a given amount of fuel is known as the maximum range speed. This is the speed at which drag is minimised. For jet aircraft ...

Safe Working Load
Safe Working Load (SWL) sometimes stated as the Normal Working Load (NWL) is the maximum safe force that a piece of lifting equipment, lifting device or accessory can exert to lift, suspend, or lower, a given mass without fear of breaking. Usually marked on the equipment by the manufacturer. It is a calculation of the Minimum Breaking Strength (MBS) also known as Minimum Breaking Load (MBL) divided by a safety factor, usually ranging from 4 to 6 on lifting equipment. The factor can be as high as 10:1 or 10 to 1, if the equipment poses a risk to a person's life. Working Load Limit (WLL) is the maximum working load designed by the manufacturer. This load represents a force that is much less than that required to make the lifting equipment fail or yield. The WLL is calculated by dividing MBL by a safety factor (SF). An example of this would be a chain that has a MBL of 2000 lbf The pound of force or pound-force (symbol: lbf, sometimes lbf,) is a unit of force used in some sy ...

Kevlar
Kevlar (para-aramid) is a strong, heat-resistant synthetic fiber, related to other aramids such as Nomex and Technora. Developed by Stephanie Kwolek at DuPont in 1965, the high-strength material was first used commercially in the early 1970s as a replacement for steel in racing tires. It is typically spun into ropes or fabric sheets that can be used as such, or as an ingredient in composite material components. Kevlar has many applications, ranging from bicycle tires and racing sails to bulletproof vests, all due to its high tensile strength-to-weight ratio; by this measure it is five times stronger than steel. It is also used to make modern marching drumheads that withstand high impact; and for mooring lines and other underwater applications. A similar fiber called Twaron with the same chemical structure was developed by Akzo in the 1970s; commercial production started in 1986, and Twaron is now manufactured by Teijin.

RV Knorr
RV ''Knorr'' was a research vessel formerly owned by the U.S. Navy and operated by the Woods Hole Oceanographic Institution for the U.S. research community in coordination with and as a part of the University-National Oceanographic Laboratory System (UNOLS) fleet. On March 14, 2016, ''Knorr'' was officially transferred to the Mexican Navy and renamed ''Rio Tecolutla''. She was replaced at Woods Hole by the . ''Knorr'' is best known as the ship that supported researchers as they discovered the wreck of the RMS ''Titanic'' in 1985. R/V ''Knorr'' (AGOR-15) has traveled more than a million miles—the rough equivalent of two round trips to the Moon or forty trips around the Earth. Her sister ship is the RV ''Melville''. Ship R/V ''Knorr'' was named in honor of Ernest R.

Robert Ballard
Robert Duane Ballard (born June 30, 1942) is an American retired Navy officer and a professor of oceanography at the University of Rhode Island who is most noted for his work in underwater archaeology: maritime archaeology and archaeology of shipwrecks. He is best known for the discoveries of the wrecks of the RMS ''Titanic'' in 1985, the battleship ''Bismarck'' in 1989, and the aircraft carrier in 1998. He discovered the wreck of John F. Kennedy's ''PT-109'' in 2002 and visited Biuku Gasa and Eroni Kumana, who saved its crew. Despite his long successes in shipwrecks, Ballard considers his most important discovery to be that of hydrothermal vents. Ballard has also established the JASON Project and leads ocean exploration on the research vessel E/V ''Nautilus''. . Downloahere Early life Robert Ballard grew up in Pacific Beach, San Diego, California to a mother of German heritage and a father of British heritage.

RMS Titanic
RMS ''Titanic'' was a British passenger liner, operated by the White Star Line, which sank in the North Atlantic Ocean on 15 April 1912 after striking an iceberg during her maiden voyage from Southampton, England, to New York City, United States. Of the estimated 2,224 passengers and crew aboard, more than 1,500 died, making it the deadliest sinking of a single ship up to that time. It remains the deadliest peacetime sinking of a superliner or cruise ship. The disaster drew public attention, provided foundational material for the disaster film genre, and has inspired many artistic works. RMS ''Titanic'' was the largest ship afloat at the time she entered service and the second of three s operated by the White Star Line. She was built by the Harland and Wolff shipyard in Belfast. Thomas Andrews, the chief naval architect of the shipyard, died in the disaster. ''Titanic'' was under the command of Captain Edward Smith, who went down with the ship. The ocean liner carri ...
