When I am at Disneyland, I can find my way to Tomorrowland, by looking for the Astro Orbiter, which mark's it's entrance. I have never actually rode the attraction. It always looks a little high up there, and there's uaually a line. It definitely does remind one of Dumbo,which is in Fantasyland.
The original ride of this type, in Tomorrowland was the Astro Jets. They loaded on ground level, just like the Astro Orbiter does. You can go up and down in the same manner as you can in Dumbo. Must be a good view up there. The Astro Jets were at Disneyland from 1956 until 1966.
In July of 1967, the D-ticket attraction Rocket Jets opened. You needed to take an elevator to the loading area of this ride. The People Mover was actually lower than the Rocket Jets ride.
The Rocket Jets closed in 1997, and the following year the Astro Orbiter began operating. No more elevator to the launch area.
Perhaps one day I will go around in circles on the Astro Orbiter. I wonder if I will get dizzy, or be afraid about how high it is?
