Question: What is the original nickname for the type of plane used in KLM Flight 861?

Context paragraphs:
Scrub plane: The scrub plane is a type of plane used to remove large amounts of wood from the surface of lumber, such as when eliminating cup or twist in the first stages of preparing rough stock, or when reducing the thickness of a board significantly.  Scrub planes generally have a short soles, a relatively narrow but thick blade, a very wide mouth, and a deeply curved edge (of about a 3 inch radius) to make a deep, gouging cut.

Boeing 747: The Boeing 747 is an American wide-body commercial jet airliner and cargo aircraft, often referred to by its original nickname, ""Jumbo Jet"".  Its distinctive "hump" upper deck along the forward part of the aircraft makes it among the world's most recognizable aircraft, and it was the first wide-body produced.  Manufactured by Boeing's Commercial Airplane unit in the United States, the original version of the 747 was envisioned to have 150 percent greater capacity than the Boeing 707, one of the common large commercial aircraft of the 1960s.  First flown commercially in 1970, the 747 held the passenger capacity record for 37 years.

Smoothing plane: A smoothing plane or smooth plane is a type of bench plane used in woodworking.  The smoothing plane is typically the last plane used on a wood surface.  When used properly, it produces a finish that equals or surpasses that made by sandpaper.  The smooth finish is the result of planing the wood off in strips, rather than by successive buffing and scratching.

Plane of reference: In celestial mechanics, the plane of reference (or reference plane) is the plane used to define orbital elements (positions).  The two main orbital elements that are measured with respect to the plane of reference are the inclination and the longitude of the ascending node.

GP Express Flight 861: GP Express Flight 861, from Hartsfield-Jackson International Airport in Atlanta, Georgia to Anniston Metropolitan Airport in Anniston, Alabama, crashed while attempting to land at approximately 8:04 a.m. CDT on June 8, 1992.  The Beechcraft Model 99 had four passengers and a crew of two on board.  There were three survivors.  Two passengers and the captain received fatal injuries.

Moulding plane: In woodworking, a moulding plane (molding plane in US spelling) is a specialised plane used for making the complex shapes found in wooden mouldings.

TWA Flight 260: 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.

KLM Flight 607-E: KLM Flight 607-E, flown by Lockheed Super Constellation named "Hugo de Groot" and registered PH-LKM, was an international scheduled flight that crashed 180 km west of Shannon, Ireland on 14 August 1958.  All ninety-one passengers and eight crew died in the accident, including six members of the Egyptian fencing team (Osman Abdel Hafeez, Mohamed Ali Riad, Ahmed Sabry, etc.).  The "E" in the flight number stood for the designation of being an extra economy class flight to match the increased seasonal tourist demand.

Jointer plane: The jointer plane (also known as the "try plane" or "trying plane") is a type of hand plane used primarily to straighten the edges of boards in the operation known as jointing.  A jointer plane may also be used to flatten the face of a board.  Its long length is designed to 'ride over' the undulations of an uneven surface, skimming off the peaks, gradually creating a flat surface.  In thicknessing or preparing rough stock, the jointer plane is usually preceded by the fore plane or jack plane and followed by the smoothing plane.

KLM Flight 861: KLM Flight 861, operated by a Boeing 747 registered PH-BUA and named "Mississippi", was hijacked on November 25, 1973, by three young Arabs over Iraqi airspace on a scheduled Amsterdam-Tokyo flight with 247 passengers on board.
