Just curious, but does anybody know if technology exists (or if there have been either rumors or ideas like this before) that would allow a seemingly "standard" rollercoaster car to, mid-ride, hook up to inverted tracks and leave the bottom tracks in a mild fashion, to create the impression of flying? I've gotten these ideas for an indoor rollercoaster using this technology and I don't know where the idea came from. It could've been sparked by some Disney rumors, for all I know. Just wondering...
