Lagoon’s Flying Saucer was a Chance Trabant with multi-colored metal panels. At night, it used over 800 lights for a radiating green glow.
When it first opened, it was located on the Midway about where Space Scrambler is now. Later, it was moved to the South Midway. It’s possible that it was moved around to a couple different spots on that end, but as shown in the photos below, the Flying Saucer was found at the very end of the South Midway in 1972 and ’73. I haven’t found any other references to the ride past 1973 so far, so it’s possible the ride was removed completely when the south station of the Sky Ride was built near that spot in 1974.
