Question: When was the airliner involved in the crash if TWA Flight 553 last delivered?
Context: TWA Flight 427 was a regularly scheduled TWA passenger flight departing Lambert-St.  Louis International Airport (STL) in Bridgeton, Missouri on November 22, 1994, operated using a McDonnell Douglas MD-82.  On the takeoff roll it struck a Cessna 441 Conquest II, killing both of its occupants.  It was the second of two flights numbered 427 that would be involved in an incident that year, the other being USAir Flight 427, which crashed in September near Pittsburgh, Pennsylvania killing all 132 on board. TWA Flight 15A (TWA 15A), a Douglas DC-2 operated by Transcontinental and Western Airways, crashed into a gully in Clifton, Pennsylvania, now Upper Saint Clair, a suburb approximately 7 miles (11 km) south of Pittsburgh.  The crash occurred at approximately 6:40 p.m. Eastern Standard Time on March 25, 1937, killing all 13 passengers and crew members.  Flight 15A was a regularly scheduled flight from Newark, New Jersey to Pittsburgh, Pennsylvania via Camden, New Jersey. TWA Flight 841 was a domestic, scheduled passenger flight from John F. Kennedy International Airport in New York City, en route to Minneapolis-Saint Paul International Airport in Minneapolis, Minnesota.  On April 4, 1979, at or around 9:48 p.m. Eastern Standard Time (01:48 UTC), while flying over Saginaw, Michigan, the Boeing 727-31 airliner began a sharp, uncommanded roll to the right, and subsequently went into a spiral dive.  The pilots were able to regain control of the aircraft and made a successful emergency landing at Detroit Metropolitan Airport. TWA Flight 260 was the Trans World Airlines (TWA) designation for a flight from Albuquerque, New Mexico to Santa Fe, New Mexico.  On February 19, 1955, the 40-passenger Martin 4-0-4 prop plane used by TWA for that route crashed into the Sandia Mountains.  Its deviation from the normal flight path, initially believed to be the result of pilot error, was revised to "unknown" given that the contribution of other factors could not be definitively ruled out. On December 20, 1972, North Central Airlines Flight 575 and Delta Air Lines Flight 954 collided on a runway at O'Hare International Airport in Chicago, Illinois, in the United States.  Ten people died – all on the North Central aircraft – and 17 were injured in the accident.  This was the second major airliner accident to happen in Chicago in December 1972; the other was United Airlines Flight 553, which crashed twelve days earlier on approach to Midway Airport. The McDonnell Douglas DC-9 (initially known as Douglas DC-9) is a twin-engine, single-aisle jet airliner.  It was first manufactured in 1965 with its maiden flight later that year.  The DC-9 was designed for frequent, short flights.  The final DC-9 was delivered in October 1982. TWA Flight 800 conspiracy theories suggest that the crash of Trans World Airlines Flight 800 (TWA 800) was due to causes other than those determined by the National Transportation Safety Board (NTSB).  The NTSB found the probable cause of the crash of TWA Flight 800 was an explosion of flammable fuel/air vapors in a fuel tank, most likely from a short-circuit.  Conspiracy theories say the crash was due to a U.S. Navy missile test gone awry, a terrorist missile strike or an on-board bomb.  On June 19, 2013, a documentary alleging that the investigation into the crash was a cover-up made news headlines with statements from six members of the original investigation team, now retired, who also filed a petition to reopen the probe. TWA Flight 513, registration NC86513, "Star of Lisbon", was a Lockheed L-049 Constellation operated by Transcontinental and Western Air on a training flight on July 11, 1946 when it crashed near Reading, Pennsylvania.  Electrical wiring in the baggage compartment arced, starting a fire.  The smoke and intense fire created made it impossible for the pilots to maintain control of the aircraft.  Of the six crewmembers aboard, five were killed.  This accident is memorable for grounding all Lockheed Constellations from July 12 until August 23, 1946 when cargo fire detection equipment could be installed.  The crash was referred to in Martin Scorsese's film "The Aviator", based on the life of TWA's then-owner, Howard Hughes. Trans World Airlines (TWA) Flight 553 was a McDonnell Douglas DC-9-15 jet airliner, registration N1063T, operated by Trans World Airlines in American airspace en route from Pittsburgh to Dayton.  While descending toward Dayton about 29 miles from the airport, the flight collided in midair with a Beechcraft Baron (a small general-aviation airplane) near Urbana, Ohio, on March 9, 1967.  All 25 people on board the DC-9 were killed, as was the pilot of the Beechcraft, its sole occupant. Kristina Borjesson is a freelance journalist.  She edited an award-winning collection of essays, "Into the Buzzsaw: Leading Journalists Expose the Myth of a Free Press" (2002), for which she wrote a chapter detailing her investigation of the TWA Flight 800 crash.  "Into the Buzzsaw" won the Arthur Rowse Award for Press Criticism and an Independent Publishers Award in the current events category.  The book was also a New York Public Library "Books to Remember"selection.  Borjesson's second book, "Feet to the Fire: The Media After 9/11, Top Journalists Speak Out" contains a series of interviews with distinguished American journalists and news executives discussing the problems of press coverage of the run-up to the Iraq War as well as the war itself.  "Feet to the Fire" also won the Independent Publishers Award in the current events category.  In July 2013, "TWA Flight 800," a feature-length investigative film Borjesson wrote, produced and directed, was released on the Epix premium cable channel.  In the film, former members of the original government investigation into the mid-air explosion of a 747 off the coast of Long Island, New York on July 17, 1996, come forward to discuss how the original investigation was undermined.  They also present forensic evidence showing what happened to the jetliner.  Previously, Borjesson won an Emmy for investigative reporting and a Murrow award for her work as Field Producer/Reporter for the CBS Reports documentary, "Legacy of Shame," updating CBS's signature documentary on migrant farmworkers, "Harvest of Shame" with Edward R. Murrow.  Borjesson also produced and co-wrote the CBS Reports biography of Cuba's Fidel Castro titled "The Last Revolutionary," which was Emmy-nominated.  For CNN's "NewsStand" show, she produced several lead pieces, including a two-part investigation of the business practices of Hollywood agents and managers.  In September 2013, Borjesson released on Amazon Kindle her first work of fiction, "The Reptile Club Librarian", a book based on the life of a man who spent most of his professional life working both sides of the law.
