What's fascinating is the propulsion system on the ride itself during the dark ride moments and launch. The dark ride portion feels a tad slower and you can feel the train slowing/speeding up to provide spacing for the vehicle in front of you. The launch itself also shutters a bit at the start and seems to change how fast you speed up. First run I noticed the launch was very slow, 2nd launch was much faster.
Also, the ride was 100% not show-ready (expected for a tech rehearsal) and had a bunch of lights on that would typically be off during the ride.
