No that was the sound of Rush Vortex doesn’t make any noise when stopped. The operator would’ve done a cycle stop/soft stop, as an e-stop on Vortex would bring the ride to an end, but would prevent the floor rising ?
I couldn’t help but laugh at parts of that article - NOT the incident itself of course, but the overly dramatic way it was written and just the general Sun language ? And a chair?!
I find the part about the staff “standing around laughing” odd and hard to believe though.
