full_context: Document 1: Ford Galaxie: The Ford Galaxie is a full-sized car that was built in the United States of America by Ford for model years 1959 through to 1974. The name was used for the top models in Ford's full-size range from 1958 until 1961, in a marketing attempt to appeal to the excitement surrounding the Space Race. For 1962, all full-size Fords wore the Galaxie badge, with "500" and "500/XL" denoting the higher series. The Galaxie 500/LTD was introduced for 1965 followed by the Galaxie 500 7-Litre for 1966. The Galaxie 500 part was dropped from the LTD in 1966, and from the XL in 1967; however the basic series structuring levels were maintained. The "regular" Galaxie 500 continued below the LTD as Ford's mid-level full-size model from 1965 until its demise at the end of the 1974 model year.

Document 4: Ford Taurus (sixth generation): The sixth generation of the Ford Taurus is a full-size car manufactured by Ford. Produced since June 2009, it is the current version of the Ford Taurus in markets outside of China. Sharing its underpinnings with its 2008-2009 predecessor, the sixth generation features a completely redesigned exterior and interior, marking the introduction of Kinetic Design for the Taurus.
Document 5: Ford F-Series (third generation): The third-generation of the Ford F-Series are trucks that were produced by Ford from 1956 to 1960. Following its competitors at Dodge and General Motors, Ford widened the front bodywork to integrate the cab and front fenders together. Going a step further, the F-Series integrated the hood into the bodywork with a clamshell design; the feature would stay part of the F-Series for two decades. Although offered previously, the optional chrome grille was far more prominent than before. In the rear, two types of pickup boxes were offered, starting a new naming convention: the traditional separate-fender box was dubbed "FlareSide", while "StyleSide" boxes integrated the pickup bed, cab, and front fenders together. As before, Ford still offered a "Low GVWR" version of each model.
Document 6: Safari Trek Motorhome: The Safari Trek was a line of Motorhomes built by the Safari Motorcoach Corporation (SMC) based out of Harrisburg, Oregon. The Trek line was developed in the late 1980s with some early model prototypes. The first official model year began in 1991 and ended in 2001 under the Safari Motorcoach Corporation banner. In 2001 SMC was purchased by Monaco Coach who took over the production of subsequent model years. The early pre-Monaco Trek's now hold a venerated status among Safari RV enthusiants-"Trekkies". This is in part due to the Trek's patented "Electro-Majic Bed" which provided for spacious floor plans. There was as well an exceptionally high build quality that used a riveted aluminum outer skin in lieu of the more popular tin or fiberglass, real hardwood cabinetry, and a small bus like design that made the Trek easy to drive and maneuver. In 2009 Monaco Coach filed for chapter 11 bankruptcy ending the "Safari Trek" line of motorhomes. The exact production numbers of the early pre-Monaco Treks have never been officially released, but estimated to be approximately 200 per year at peak production during the ten-year run. Much of this is derived from former employees and customers who took the factory tours that Safari Motorcoach Corporation would give to potential buyers. Since there is no official registry, it is difficult to know how many are still on the road today.
Document 7: Ford Explorer: The Ford Explorer is a full-size sport utility vehicle produced by the American manufacturer Ford Motor Company since 1990, based since 2010 on a crossover platform. The Ford Explorer became one of the most popular sport utility vehicles on the road. The model years 1991 through 2010 were traditional body-on-frame, mid-size SUVs. For the 2011 model year, Ford moved the Explorer to a more modern unibody, full-size crossover SUV platform, the same Volvo-derived platform the Ford Flex and Ford Taurus use although with significantly greater ground clearance. It is slotted between the traditional body-on-frame, full-size Ford Expedition and the mid-size CUV (Crossover Utility Vehicle) Ford Edge. Although outwardly similar, the fifth generation Explorer, Ford Edge and Ford Escape do not share platforms. The fifth generation Explorer does, however, share platforms with the Ford Flex and Lincoln MKT.

The ride features a loop, a sidewinder, and a double corkscrew. It was originally built for and located at Expo '86 in Vancouver, B.C., operating as Scream Machine from May to October 1986. It began operating as Ninja at Six Flags St. Louis in 1989. The coaster was started by Arrow Dynamics, but when Arrow fell into bankruptcy, it was sold to Vekoma, who finished it. The ride is formerly shared a name with Blue Hawk at Six Flags Over Georgia until that coaster's retheming in 2016. Another roller coaster with the same name exists at Six Flags Magic Mountain, but that ride is an Arrow Dynamics suspended swinging coaster. The Ninja, like most modern roller coasters, requires a minimum of two employees to dispatch the train. One operates the main panel, which controls the restraints, gates, and has a section for the mechanics. The other operator stands at the remote enable. Both operators have to do an all clear sweep and thumbs up, then press their buttons at the same time.

Document 11: Ford F-Series (seventh generation): The seventh generation of the Ford F-Series is a line of pickup trucks and medium-duty commercial trucks that was produced by Ford from 1979 to 1986. For the first time since 1965, the pickup trucks were based upon a completely new chassis and body. Distinguished by its squarer look, sharper lines and flatter panels, the trucks were designed with improved fuel efficiency in mind; to this end, Ford added its new AOD automatic overdrive (four-speed) transmission as an option on light-duty models. The 4-speed manual and 3-speed C6 automatic transmission were retained from previous years. To increase longevity, Ford increased the use of galvanized body panels to fight corrosion. Pickup trucks were available in three body styles: regular cab, SuperCab extended cab or crew cab with two bed lengths. The crew cab trucks were very large, stretching nearly 20 feet long with an eight-foot bed. These trucks are considered amongst enthusiasts to be the last generation of great trucks built by Ford and are now beginning to become popular amongst restorers as the models have just reached classic car status. They are typically considered to be the last of the "classic" Ford trucks, due to the fact it had features such as glass "eyed" headlights that made the truck appearing to have a set of two eyes.
