Students Scramble to Save Friends as Stage Collapses at High School in Indiana

It was a moment straight out of glee. Only this high school musical production ended in disaster when the stage collapsed. Approximately 50 to 60 people were trapped underneath the stage.

The students were performing a song that's been featured on glee. The Westfield Indiana High School version was just like it.

Seventeen teenagers were injured when the stage collapsed without warning during the spring musical at the school outside Indianapolis.

Student Reid Markus told WISH TV, "All of a sudden I just hear like this loud thud and the floor just collapsed right beneath my feet. It happened so quickly, I was on the ground before I knew what happened."

The high school is just 28 miles from the site of the horrific stage collapse that killed seven as a thunderstorm approached the Indiana State Fair in 2011.

So what went wrong with the high school stage collapse?

INSIDE EDITION asked crowd safety expert Paul Wetheimer to analyze the video.

Wetheimer said, "I think you'll find that the structure was never built for this kind of capacity of people jumping up and down, creating extraordinary pressure."
