It’s probably not a whole lot different than BTMRR actually, maybe a little tighter.[/QUOTE]
I understand it’s your opinion, but I have to disagree.
Big Thunder and Space Mountain are very different animals though I see why you’d feel as you do.
It’s the multiple helix elements on both coasters, and yes, Space’s are much tighter, if for no reason other than the Big Thunder trains being very much longer, heavier, and wider.
For me, Space Mountain reminds me of the boardwalk wild mouse coasters that used to be in a few places on the Jersey shore. Tight and dense layouts with quick drops and very tight turns.
Big Thunder, on the other hand, is the most evolved (themed) version of the runaway mine train coaster in the world. There are two coasters in WDW that are related. Of course Everest is considered an oversized mine train coaster (with two one of a kind on ride switches) and is Big Thunder’s big brother. The other coaster is The Barnstormer, a family coaster with a smooth, fun layout. Big Thunder and all mine trains, are oversized family coasters once you get under the hood.
We all know any discussion of coasters brings this out in me.
