Which roller coaster, opened in 1975, is a part of the Walt Disney World Quest Magical Racing Tour?
Walt Disney World Quest: Magical Racing Tour:  Players compete in races on tracks inspired by attractions such as the Haunted Mansion, Pirates of the Caribbean, Space Mountain and Big Thunder Mountain Railroad to acquire missing parts for the park's fireworks machine, which was accidentally destroyed by Chip 'n' Dale while they were gathering acorns. Space Mountain (Magic Kingdom):  Opened on January 15, 1975, Space Mountain is the oldest operating roller coaster in the state of Florida, and is the original version of the iconic attraction that has since been replicated at all of The Walt Disney Company's Magic Kingdom-style theme parks worldwide, except for the Shanghai Disneyland Resort.
