December

December is the twelfth and final month of the year in the Julian and Gregorian Calendars. It is the last of seven months to have a length of 31 days. December got its name from the Latin word decem because it was the tenth month of the year in the calendar of Romulus c. 750 BC which began in March. The winter days following December were not included as part of any month; the months of January and February were created out of the monthless period and added to the beginning of the calendar, but December retained its name. In Ancient Rome, as one of the four Agonalia, this day in honor of Sol Indiges was held on December 11, as was Septimontium. Dies natalis was held at the temple of Tellus on December 13, Consualia was held on December 15, Saturnalia was held December 17–23, Opiconsivia was held on December 19, Divalia was held on December 21, Larentalia was held on December 23, the dies natalis of Sol Invictus was held on December 25; these dates do not correspond to the modern Gregorian calendar.

Viasa Flight 897

Viasa Flight 897 refers to an international scheduled Rome–Madrid–Lisbon–Santa Maria–Caracas passenger service that crashed into the Atlantic Ocean off the coast of Portugal on 30 May 1961, shortly after takeoff from Portela Airport. There were no survivors among the 61 occupants of the aircraft. Named Fridtjof Nansen, the aircraft involved in the accident was a Douglas DC-8-53, registration PH-DCL, owned by KLM and operated on Viasa's behalf. With constructor's number 45615/131, the airframe was the newest one of the type in KLM's fleet at the time the accident took place; the crash of Viasa Flight 897 occurred on the third leg of a trip that originated in Rome and was scheduled to conclude in Caracas, Venezuela. Intermediate stops were to be made in Madrid, Lisbon, on Santa Maria Island. At the time the airliner lifted off from Lisbon at 01:15 UTC, the nighttime sky had a cloud base of 3,700 feet. A few minutes after take off the DC-8 entered a spiral dive to the left shortly after sending two short messages to Air Traffic Control.

The pilot over-corrected to the right and the aircraft struck the sea with a pitch angle of 25° nose down. The cause for the crash of Viasa Flight 897 was never determined by either Portuguese or Dutch authorities; the official report out of Portugal concluded "Notwithstanding a thorough, time-consuming investigation, in which many authorities and experts co-operated, it was not possible to establish a probable cause of the accident." The Netherlands, as state of registry for the aircraft, commented: "Though there are no direct indications in this respect, the Board regards it as possible that the accident was due to the pilot or pilots being misled by instrument failure, in particular of the artificial horizon, or to the pilot having been distracted, so that a serious deviation from the normal flight path was not discovered in time." At the time it occurred, Flight 897 was the third fatal crash of a big jetliner since they were introduced into service in 1958. It was the worst civilian aviation incident to take place in Portugal until the crash of TAP Air Portugal Flight 425 in 1977.
