and, like at Disneyland, was opened unfinished. On opening day, only two attractions opened: the Grand Prix Raceway, and the Skyway to Fantasyland. Tomorrowland was noted for being very barren and sterile at this time, due to the land being very flat and undetailed. A large orange wall was located past the two large show buildings, and blocked guests from walking further than the Skyway building. The wall had a small stage built into it, and a large outdoor food court sat adjacent to it to compensate for a lack of food venues at the time. It was removed within two years and the Carousel of Progress took its place. The largest counter service restaurant in the Magic Kingdom was the Tomorrowland Terrace. America the Beautiful opened in November, and Flight to the Moon opened late on Christmas Eve, 1971, due to technical problems. The south show building received an expansion in 1972, which housed If You Had Wings. The south building was further expanded in 1973, opening the Plaza Pavilion, which was an open-air restaurant, and served as a convenient way of getting from Main Street to Tomorrowland quickly. In 1973, the plans for Tomorrowland were finalized; and for about two years, construction was a common sight. In 1974, Star Jets, a spinner attraction sat on the WEDWay Peoplemover station. It resembled a Saturn V Rocket like its Disneyland cousin, the Rocket Jets. The ride vehicles between the two had some differences. The Disneyland Rockets were more narrow and resembled the central Saturn V rocket more, while the Magic Kingdom's vehicles look more like jets, hence the name "Star Jets".The Space Bar, another restaurant opened below the Peoplemover station. The next year, Space Mountain and The Carousel of Progress opened on January 15. This was the first Space Mountain to open. It was the first totally indoor roller coaster in Florida and was the first roller coaster to have computer aided designs and use zoning to have 8 trains on the track at a time. Another Railroad station was planned to be built next to the entrance and exit to Space Mountain, but due to crowds in this area, it was never built. Carousel of Progress opened on the same day, and was similar to Disneyland's version except it rotated in the opposite direction. It also had a different song: Instead of "There's a Great Big Beautiful Tomorrow", the
