Riding the world’s tallest water slide has cost the life of a 10-year-old boy, Caleb Thomas Schwab, on Sunday.

The boy was the son of Kansas State representative Scott Schwab. The adventure at Kansas City’s Schlitterbahn Water Park claimed the life of the boy. The water slide has been reported unsafe for a long time. Travel Channel documentary “Xtreme Waterparks” stated that the water slide was declared unsafe in 2014 and was recorded to be so in the Guinness Book of World Records.

The above revelation about the water slide being unsafe came only after the death of the boy. According to reports, a “glitch” caused water rafts to flow beyond the slides and enter the air. This was one of the problems that creators and designers looked into and rectified ahead of the grand opening of the adventurous site in July 2014.

When USA Today had an interview with creator Jeff Henry in 2014, he agreed with the flaws relating to the world’s tallest water slide. “We had many issues on the engineering side. Our correction coefficients were all off. Models didn’t show air and water friction. A lot of our math was based on roller coasters at first, and that didn’t translate to a water slide like this. No one had ever done anything like this before.”

Schwab and wife Michele issued a statement on Sunday where they confirmed the death of their son while riding the Verrückt slide at the adventure park.  The official website of the park also mentioned the incident.

According to US Magazine, visitors in the park had grievances related to the working of the harness. They said that the day when the boy died, the harness that was used to fasten passengers into the slide was not working properly.

Schlitterbahn Water Park will remain closed on Monday and the Verruckt  slide will be closed as long as the investigation on the matter is not complete.
