However, even though it is enjoyable, it will be a different story if the ride suddenly experiences an error that poses a risk to safety. This nightmare was experienced by dozens of roller coaster passengers at Universal Studios, Osaka, Japan last Wednesday. They were left hanging at a height equivalent to a 10-storey building. To make matters worse, the machine was stuck in an upside-down position.

The Roller Coaster Flying Dinosaur suddenly stopped in the middle of the track on May 1, 2018, leaving passengers hanging upside down for about two hours. The ride they were on malfunctioned and abruptly stopped at separate points along the 1,120-meter track. The park operator stated that the damage occurred due to a defective part in the train's control device.

According to NHK's report, another roller coaster at Universal Studios Japan also experienced the same mechanical problem. On January 22, 2022, around 30 people had to be rescued from the Hollywood Dream ride. They were trapped, sitting upright, for about 90 minutes before being rescued. This incident occurred three months after the same roller coaster suddenly stopped due to a power disruption, trapping 35 people. (Report: M Bintang Alfan Nur Fauzi)
