Question: Queen of the Netherlands is a Dutch Trailing suction hopper dredger ship, constructed in 1998, the vessel has been used in high-profile salvage and dredging operations including the investigation into which scheduled international passenger flight from New York City, United States, to Geneva, Switzerland, the flight was also a codeshare flight with Delta Air Lines?

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. <SEP>  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. Swissair Flight 111 (ICAO: SWR111) was a scheduled international passenger flight from New York City, United States, to Geneva, Switzerland.  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. <SEP> 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". <SEP> 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.
