Due to a technical glitch, the attraction began to rotate backwards and spun like this without stopping for 10 minutes. Unfortunate people could only cry for help, because these 10 minutes seemed like an eternity to them.
In the end, the Music Express was stopped, and all the rescued were examined by doctors. No one was hurt, but visitors are understandably unhappy - especially with how slow the park staff were in putting them through such torture. The attraction should have been stopped much earlier.
It is unfortunate, but the incident caused Internet users not only sympathy, but also jokes. The most common joke is that the Music Express has become a time machine. If people scrolled for another 10 minutes, they would go back in time.
