Context paragraphs:
Swissair Flight 111: Swissair Flight 111 (ICAO: SWR111) was a scheduled international passenger flight from New York City, United States, to Geneva, Switzerland.  This flight was also a codeshare flight with Delta Air Lines.  On 2 September 1998, the McDonnell Douglas MD-11 performing this flight, registration HB-IWF, crashed into the Atlantic Ocean southwest of Halifax International Airport at the entrance to St. Margarets Bay, Nova Scotia.  The crash site was 8 km from shore, roughly equidistant from the tiny fishing and tourist communities of Peggy's Cove and Bayswater.  All 229 passengers and crew aboard the MD-11 died—the highest death toll of any McDonnell Douglas MD-11 accident in aviation history, and the second-highest of any air disaster to occur in Canada, after Arrow Air Flight 1285, which crashed in 1985 with 256 fatalities.  This is one of the three MD-11 accidents with passenger fatalities along with China Eastern Airlines Flight 583 and another hull loss of China Airlines Flight 642.

WD Mersey: The TSHD "WD Mersey" is a British trailing suction hopper dredger, owned and operated by Boskalis Westminster Ltd (known as Westminster Dredging Company until 2014) and built in Italy.  The ship maintained ports around the British Isles, including Liverpool, the Manchester Ship Canal, Harwich, Heysham and the Firth of Clyde

Sospan Dau: The TSHD Sospan Dau is a Dutch trailing suction hopper dredger owned by Sosban BV.  The vessel has worked on dredging projects, including offshore aggregates, port maintenance, land reclamation, coastal defense and beach replenishment.  The name "Sospan Dau" is Welsh and originates from Sosban Fach and Llanelli's tin plating industry, Sospan being the Welsh for Saucepan and "Dau" being Welsh for Two as the ship is a successor to the original Sospan.

Northwest Airlines Flight 253: Northwest Airlines Flight 253 was an international passenger flight from Amsterdam Airport Schiphol in Haarlemmermeer, Netherlands, to Detroit Metropolitan Wayne County Airport in Romulus, Michigan, United States.  The flight was the target of a failed al-Qaeda bombing attempt on Christmas Day, December 25, 2009, in which a passenger tried to set off plastic explosives sewn to his underwear.  There were 290 people on board the aircraft—an Airbus A330-323E operated by Northwest Airlines, which had merged with Delta Air Lines the year before.  Had the attempt succeeded, it would have surpassed American Airlines Flight 191 as the deadliest aviation occurrence on U.S. soil and tied Iran Air Flight 655 as the eighth-deadliest of all time.  The incident was also the second in 2009 involving an Airbus A330, after the crash of Air France Flight 447 on June 1.  This was also the final accident/incident involving Northwest Airlines as it closed down a month later when it merged with Delta Air Lines.

Air Caraïbes Flight 1501: Air Caraïbes Flight 1501 (TX1501/FWI1501) was a scheduled international passenger flight, flying from Saint Martin Airport in the Dutch overseas territory of Sint Maarten to Saint Barthélemy Airport in the French overseas region of Guadeloupe.  The flight was operated by Air Caraïbes, a Caribbean regional airliner, using a de Havilland Canada DHC-6-300 Twin Otter.  On 24 March 2001, during an approach to Saint Barthélemy Airport, the DHC-6 Twin Otter banked steeply to the left and crashed onto a house, killing all 19 passengers and crews on board.  One person on the ground was also killed in the explosions that followed.

Delta Air Lines Flight 1086: Delta Air Lines Flight 1086 (DL1086/DAL1086) was a scheduled Delta Air Lines domestic passenger flight between Atlanta and New York's LaGuardia Airport.  On March 5, 2015, the McDonnell Douglas MD-88 aircraft veered off the runway shortly after landing at LaGuardia Airport in New York City.  The plane ran up the seawall berm and struck the perimeter fence, sliding along it for approximately 940 ft before coming to rest with the nose of the aircraft hanging over the berm above Flushing Bay.  There were no fatalities, although 24 people suffered minor injuries.  The aircraft was seriously damaged.

Queen of the Netherlands (ship): Queen of the Netherlands is a Dutch Trailing suction hopper dredger ship constructed in 1998.  After lengthening in 2009, she was the largest and most powerful dredger in the world.  The vessel has been used in high-profile salvage and dredging operations including the investigation into the Swissair Flight 111 crash and in the Port Phillip Channel Deepening Project.  It has been called "the world's largest floating vacuum cleaner".

Delta Air Lines Flight 191: Delta Air Lines Flight 191 was a regularly scheduled Delta Air Lines domestic service from Fort Lauderdale, Florida, to Los Angeles, via Dallas that crashed on August 2, 1985, at 18:05 ().  The Lockheed L-1011 TriStar operating this flight encountered a microburst while on approach to land on runway 17L (now marked 17C) at Dallas/Fort Worth International Airport (DFW).  The pilots were unable to escape the weather event and the aircraft struck the ground over a mile short of the runway.  The flight hit a car driving north of the airport and two water tanks, disintegrating.  The crash killed 136 people on board, including 128 of the 152 passengers and 8 of the 11 crew, and the driver of the car.  The National Transportation Safety Board (NTSB) determined that the crash resulted from the flight crew's decision to fly through a thunderstorm, the lack of procedures and training to avoid or escape microbursts, and the lack of hazard information on wind shear.

Trailing suction hopper dredger: Trailing suction hopper dredger is a ship that has a full sailing capacity used to maintain navigable waterways, deepening the maritime canals that are threatened to become silted, to construct new land elsewhere or to replace sand eroded by storms or wave action on the beaches.  This made possible by large powerful pumps and engines able to suck sand, clay, silt and gravel.

Delta Air Lines Flight 1141: Delta Air Lines Flight 1141 was a scheduled domestic passenger flight between Dallas/Fort Worth, Texas and Salt Lake City, Utah.  On August 31, 1988, the flight, operated by a Boeing 727, crashed during takeoff, killing 14 of the 108 people on board, and injuring 76 others.
