These two clips were obtained using a process developed by Concourse Six Laboratories in which one leaves an audio recording device in a Disney ride and returns later to retrieve it. You therefore get several looping full segments and one hell of an idea of the atmosphere in that portion of the ride. The proper term used to describe this maneuver is "Drop Off".
This is when we did a drop off in the "Choose your Tomorrow" star field room.
Of course in the Space scene with all of the different sounds.
More to come. Enjoy!
