Oh yes! I definitely remember it! The ride vehicles looked exactly like the Haunted Mansion Doom Buggies, except they were blue! There was never any line for the ride, so you could walk right on it again and again. I loved it. That was definitely a part of the old Tomorrowland, and was kind of cheesy in that good Disney way, but I miss it! I can't believe Star Tours has been there since 1987, so that means Inner Space has probably been gone since 1986, right? I remember riding it in early 1986, but they must have removed it immediately after that. I also miss the People Mover and the old phone booths they used to have in Tomorrowland, where you could fit like 5 people in a booth, and you would all go in and sit on these seats and talk to the wall (the speaker was in the wall). Such fun retro-future stuff!
I actually do like Star Tours because of the motion simulator concept, but many folks feel the film is getting old and tired and needs to be changed.
