A couple has been praised for their quick actions when they realized tat a girl behind them was panicking because of a horrible roller coaster malfunction.

A day at Worlds of Fun amusement park in Kansas City, Missouri, became a nightmate for a girl when her seatbelt came undone while on a roller coaster at the park on October 11.

The couple infront of her immediately sprang to action when they noticed that the girl’s seatbelt on the Mamba roller coaster came undone. They heard the girl screaming not in excitement but in pure fear.

The couple Chris and Casie Evins later spoke the media about the terrifying incident and reflected on their quick actions that likely saved the young girl’s life.

As with most roller coaster , a picture was taken mid-ride that showed how the couple had helped the girl stay in her seat.

Chris said while speaking to the media, “We get on the roller coaster and the very first hill, the girl sitting behind my wife just lets out this blood-curdling scream like I’ve never heard before.”

He said he initially thought that perhaps the girl is on a ride such as this for the first time but he quickly realized that something was wrong when she began screaming that her seatbelt had come undone.

The ride can reach up to 75mph and heights of 205ft. Without thinking twice, the couple turned and tried their best to help keep the girl secure in her seat.
