Videos show the terrifying moment a young student going rope swinging was thrown off a 130-foot bridge – without a rope attached.

Three bungee-jumping instructors have now been charged in the death of the 21-year-old in Brazil who plummeted to her death as the safety rope could be seen lying unused on the platform.

The incident has since gone viral, along with resurfaced videos of the same instructors performing risky-looking stunts with a child, sparking outrage.

With fears rising about the dangers of participating in the extreme activity, we spoke with a bungee jump expert to break down everything that went wrong.
