Interesting! Of course for any new ride to be placed on the slab. it would mean the removal/relocation of the Tumblebug. The concrete slab , as it stands, originally supported the Big Dipper station and track supports. If it can handle the weight of the Tumblebug, then I am confident it could accommodate a new compact coaster, if one was to be installed. The question that needs to be asked, however , is can the Flying saucer "pad" handle the weight of the Tumblebug? If it can then this would be my choice on where to relocate it in the park, freeing up the necessary space on the Tumblebug site for a new coaster.
You are correct in saying that some of the LPS offices are still located behind the Flying saucer site.
Agree with your comments RE the Flying Saucer. They are such a unique ride and now that LPS unit is gone, there are only about 12 left in existence.
Here is some info about the Huss UFO taken from Dave Burton's Amusement Extravaganza page.
"The HUSS UFO premiered in 1978 based on their successful Enterprise design. With passengers standing up and facing inwards, an entirely different ride sensation results to the enterprise; similar to a Roundup but with a greater diameter and incline of 87°
Holding 48 standing adults or children in twelve 4-person gondolas, this 20m/66ft diameter HUSS monster holds a commanding presence as one of the best standup gravity ride sensations around.
UFO was never quite as popular as the Enterprise with approximately 12 units in existence mainly in Europe, two in North America and one in Sth Africa America."
I actually think a Techno Jump would be an excellent choice for a ride at LPS, but I don't think it should be placed on the Flying Saucer site. Techno Jumps are great family rides, a little bit unique and also no park in Australia has one. I think it would prove extremely popular.
