Looking through old maps it seems like the building first appears in 1990, though without a label (it’s tucked half in frame to the left of The Missile). I can’t seem to find an 89 map, so can’t say if it appears on that one, but I wouldn’t expect it to appear any earlier as that area of the park hadn’t been developed then, had it?
There’s also this map apparently from 1990 as well, which includes a list of attractions in the area. The only ones I can’t really put anything to are G-Force or Outer Limits. No idea what those are and if they maybe have anything to do with the building? Interesting side-note, notice how this map includes Buffalo but it’s missing from the previous image. Assuming this is some kind of error, as there shouldn’t be any case where The Missile is featured and Buffalo isn’t, as far as I’m aware.
Interestingly the building doesn’t appear to be present on this map in 1993.
In 95 it reappears again, tucked off the side but again seems quite unassuming and doesn’t look to have an attraction number overlaid on it.
The front cover of this year’s map also says 2 new rides, those being Iron Wolf/Twin Looper and Alien, so although the building comes back onto the map it doesn’t appear to have any real significance (not as a ride at any rate).
On the 1997 map it’s labelled as Black Hole and has a “NEW” marker over it. I’ve always wondered what it was but I’ve never known what was inside.
On the 1999 map it’s referred to as Cyber Storm. Was this the name it had when it became the laser dodgems?
What with it appearing, disappearing, and seeming to go unmarked up until 1997, I wonder if the building was just some sort of facilities/storage location, or maybe a shop/F&B outlet for the first half of its life. Then it became Black Hole (whatever that may have been) for a few years, before then changing to the dodgems in 1999 for the remainder of its life.
Also does anyone remember, there was a second dome in Spaceport, much closer to the train tracks with a sign on the door saying “closed for refurbishment” from about 1998 until the year the park closed.
I think that dome was the cinema style attraction you’re referring to? It’s listed on one of the above maps as Screen 2001.
