Question: Crash Landing, is a 1958 dramatic, "disaster" film directed by Fred F. Sears, and was based on Pan Am Flight 6, was an around-the-world airline flight that ditched in the Pacific Ocean on which date, after two of its four engines failed?
Context: Pakistan International Airlines (PIA) Flight 688 (PK688, PIA688) was operated by Pakistan's flag carrier Pakistan International Airlines as a domestic passenger flight from Multan to Lahore and Islamabad.  At 12:05 pm on 10 July 2006, the Fokker F27 deployed on the route crashed into a field when one of its two engines failed shortly after takeoff from Multan International Airport.  All 41 passengers and four crewmembers on board were killed.  It was the deadliest plane crash in Pakistan until 2010 when an Airbus A321 flew into Margalla Hills in Islamabad while on approach to Benazir Bhutto International Airport. The 1987 Alianza Lima air disaster took place on 8 December 1987, when a Peruvian Navy Fokker F27-400M chartered by Peruvian football club Alianza Lima plunged into the Pacific Ocean six miles short of its destination, off the Ventanilla District of the city of Callao.  On board the flight were a total of 44 players, managers, staff, team supporters, and crewmembers, of whom only the pilot survived the accident.  The team was returning from a Peruvian league match in Pucallpa.  Uncomfortable with the malfunctioning indicator on his control panel, the pilot requested a flyby of the control tower at Lima's Jorge Chávez International Airport so that spotters on the ground could confirm that the aircraft's landing gear was down and locked.  Upon receiving visual confirmation of safe configuration for landing, the aircraft went around for another attempt at a landing, during which the aircraft flew too low, hitting the Pacific Ocean. Helicopter Underwater Egress Training in the United States, and Helicopter Underwater Escape Training in most other countries, (often abbreviated HUET, pronounced "hue-wet", "hue-way" or "you-way") is training provided to helicopter flight crews, offshore oil and gas industry staff law enforcement personnel, and military personnel who are regularly transported by helicopters over water.  As the name implies, the purpose is to prepare them for emergency exit in the case of a crash landing over water.  While the training may be taken by crew and frequent passengers in all small aircraft that could ditch over water, a fixed wing aircraft such as a seaplane or small jet is not as prone to rollover as quickly or sink as rapidly as a helicopter with its main rotor on top of the aircraft.  In addition, due to the slow speed of helicopters versus fixed wing aircraft and the lower height above the water, their cabins have a greater chance of being intact with passengers inside when ditched in the water. Scandinavian Airlines Flight 751 was a regularly scheduled Scandinavian Airlines passenger flight from Stockholm, Sweden, to Warsaw, Poland, via Copenhagen, Denmark.  The McDonnell Douglas MD-81, registration OY-KHO, was piloted by Danish captain Stefan G. Rasmussen (44) and Swedish first officer Ulf Cedermark (34).  On 27 December 1991, ice had collected on the wings' inner roots (close to the fuselage) before takeoff.  It broke off and was ingested into the engines as the aircraft became airborne on takeoff.  After both engines failed, the pilots were forced to make an emergency landing in a field near Gottröra, Sweden.  All 129 passengers and crew aboard survived. Crash Landing (aka Rescue at Sea) is a 1958 dramatic, "disaster" film directed by Fred F. Sears, starring Gary Merrill and Nancy Reagan.  This was the last film in which Nancy Reagan (billed as Nancy Davis) appeared, though she continued to work in television for some years thereafter.  "Crash Landing" was based on Pan Am Flight 6, a real-life ditching at sea. The Swamp Ghost is a Boeing B-17E Flying Fortress piloted by Captain Frederick 'Fred' C. Eaton, Jr, that ditched in a swamp on Papua New Guinea during the Second World War, after a raid on ships at Japanese-occupied New Britain on February 23, 1942.  While flying over Rabaul, it was intercepted and eventually, having run out of fuel, had to force-land in a remote swamp near the north coast of New Guinea.  All of the crew survived the crash landing and arduous trek out. On 15 December 1989, KLM Flight 867, en route from Amsterdam to Narita International Airport Tokyo, was descending to Anchorage International Airport Alaska when all four engines failed.  The Boeing 747-400 combi, less than six months old at the time, flew through a thick cloud of volcanic ash from Mount Redoubt, which had erupted the day before. Air France Flight 66 (AF066) is a scheduled international passenger flight from Paris Charles de Gaulle Airport to Los Angeles International Airport, operated by Air France using an Airbus A380.  On 30 September 2017, the aircraft suffered an uncontained engine failure and made an emergency landing at Goose Bay Airport, Canada at 15:42 GMT, or 12:42pm local time.  The failure occurred west of Nuuk, Greenland, over the Atlantic Ocean, while the aircraft was en route.  The cause of the failure to the aircraft's No. 4 Engine Alliance GP7000 engine is still undetermined with the airline saying that it suffered "serious damage to one of its four engines." The 2000 Marsa Brega Short 360 crash occurred on 13 January 2000 when a fully loaded Swiss-registered Short 360 leased by Avisto ditched into the sea near Marsa Brega in Libya.  The aircraft was chartered by Sirte Oil Company to transport oil workers to the city.  It was carrying 41 people (38 passengers and three crew).  Most of the passengers were foreigners.  As both engines failed in mid-flight, the crew chose to ditch the aircraft.  The crash claimed the lives of 21 people.  An official investigation concluded that the de-icing device on the aircraft was not activated.  The aircraft flew into an adverse weather condition and an icing condition occurred in mid-flight.  The ice melted and flooded the engine, causing both engines to fail.  The Libyan Civil Aviation Authority also blamed the pilots for conducting conversation unrelated to the flight. Pan Am Flight 6 (registration N90943, and sometimes erroneously called Flight 943) was an around-the-world airline flight that ditched in the Pacific Ocean on October 16, 1956, after two of its four engines failed.  Flight 6 left Philadelphia as a DC-6B and flew westward on a planned multi-stop trip.  It stopped at San Francisco International Airport, then flew onward to Honolulu.  On the evening of October 15, 1956, the flight left Honolulu on a Boeing 377 Stratocruiser named "Clipper Sovereign Of The Skies" (Pan Am fleet number 943, registered N90943).  The accident was the basis for the 1958 film "Crash Landing".
Answer: October 16, 1956
