Ok, and I'm disputing that is the case. But does anyone have any actual "evidence" of this besides some anecdotal "well this wasn't there before" situation? Like any actual plans, video, pictures, anything?
I mean its nice to take someones word for it, but it makes it better when dealing with actual fact based evidence for these discussions.
Plans for the '67 tunnel were posted above. I enlarged them and colored in the tunnel. I didn't highlight it, but there's a boxed out area indicated by dotted lines under the stage.
I don't remember where I read the information from, but the northwest end of the tunnel can be accessed by one of these doors:
It's not really relevant to the discussion, but thought it was a fun factoid.
This isn't an official blueprint, but gives the idea of where the '98 Rocket Rods queue tunnel was located:
Here is a real-world approximation (red is Rocket Rods, yellow is '67 utility tunnel)
This can be somewhat corroborated in this video:
It looks like after watching the movie on the old circlevision screens, they went to that southeast corner to go underground. They also emerge back above ground under the RR/PM loading platform.
As I was researching this, I saw on a message board that someone said the current entrance is still in the back corner of the Little Green Men store. This shot is in the direction of the old stairway and it's probably accessed through one of these doors:
Take it or leave it, but it's probably the most "evidence" you'll find on the internet. I'll say that is is possible the underground area under the Tomorrowland Terrace was connected to the Rocket Rods tunnel, but all things seem to point toward the RR tunnel being purpose-built in '98 based on the location of the '67 tunnel and its lack of being on the '67 blueprint.
