Context: Empire Explorer was a  GRT cargo ship that was built as the cargo liner Inanda in 1925 by Swan, Hunter & Wigham Richardson Ltd, Newcastle upon Tyne, Northumberland, United Kingdom for a British shipping line.  She was hired by the Royal Navy in 1940 for use as an ocean boarding vessel but was sunk in an air raid London in September 1940.  She was salvaged, rebuilt as a cargo ship, passed to the Ministry of War Transport (MoWT) and renamed Empire Explorer.  She served until 9 July 1942, when she was torpedoed and sunk by "U-575" in the West Indies. The Erie L. Hackley was a passenger and cargo ship that operated in Lake Michigan from 1882 to 1903.

Discovered by divers from the French Navy Diving School in 1967, the archaeological investigations of the Roman wreck at Madrague de Giens constituted the first large scale, “truly scientific underwater excavation[s] carried out in France”.  The wreck lies at around 18 to 20 metres depth off the coast of the small fishing port of La Madrague de Giens on the Giens peninsula, east of Toulon, on the southern Mediterranean coast of France.  Sunk around 75-60 BCE, the vessel has been found to be “a large merchantman of considerable tonnage - 400 tons deadweight with a displacement of around 550 tons”, making it one of the largest Roman wrecks excavated, with only the wreck at Albenga, Italy (around 600 tons deadweight) exceeding it at the time of its discovery.  The vessel wrecked at Madrague de Giens measured around 40 metres in length; “showed a sharp bottom with “wine glass” section and a prominent keel creating a large leeboard”; displayed extended raking of the stem and stern; and had two masts.  The hull was characterised by a reverse stempost in the shape of a ram with a big cutwater which “must have given... [the] craft high-performance sailing qualities”.  The ship sunk while transporting a large cargo of wine and black glazed pottery from Italy.  It is not known why it sank. HMS "Cornwall", pennant number 56, was a County-class heavy cruiser of the "Kent" sub-class built for the Royal Navy in the mid-1920s.  The ship spent most of her pre-World War II career assigned to the China Station.  Shortly after the war began in August 1939, she was assigned to search for German commerce raiders in the Indian Ocean.  "Cornwall" was transferred to the South Atlantic in late 1939 where she escorted convoys before returning to the Indian Ocean in 1941.  She then sank the German auxiliary cruiser "Pinguin" in May.  After the start of the Pacific War in December 1941, she began escorting convoys until she was transferred to the Eastern Fleet in March 1942.  The ship was sunk on 5 April by dive bombers from three Japanese aircraft carriers during the Indian Ocean Raid. American Airlines Flight 444 was a Boeing 727 flying from Chicago to Washington, D.C.'s National Airport, which on November 15, 1979, was attacked by the Unabomber.  The bomb planted in the cargo hold caused "a sucking explosion and a loss of pressure," which was then followed by large quantities of smoke filling the passenger cabin, forcing the pilots to make an emergency landing at Dulles International Airport.  Twelve passengers had to be treated afterward for smoke inhalation.  It was later determined that the bomb was powerful enough to have destroyed the aircraft had it worked correctly. The savarin mould is a large ring shaped mould, designed originally with an accompanying gâteau recipe in mind.  It was created by the Julien brothers, Parisian pastry chefs who owned Julien Frères, a respected pastry shop in Paris in the mid 19th century.  The name Savarin is given in honour of Jean Anthelme Brillat-Savarin, the famous French gourmet, who gave Auguste Julien the recipe for the rum syrup used in the original Savarin Gâteau.  The moulds are in modern times, however, used for many preparations, sweet and savoury, including meat, seafood, and vegetable dishes, as well as cakes, breads, mousses and jellies.
