Christian Kendall says the SUV involved flipped at least 14 times before disappearing off interstate.
Kendall says it was like something out of a movie.
"It was the tightest spiral I'd ever seen. A car, something that weighs upward of 4, 500 to 6,000, pounds spinning like that, I’ve never seen anything like that," says Kendall.
Kendall witnessed that three car crash on I-264, Monday.
He says he watched as a mid-sized SUV flipped several times after being hit from behind rolling right off the interstate.
That Chevy Blazer plummeted 25-feet down to the railroad tracks below at Greenwich Road.
State police say the driver and his 15-year-old passenger were both taken to the hospital.
As for Kendall, he says when he saw what happened he pulled over then slid down a 20-foot embankment to help.
“The driver was cognoscente enough to scream because he was screaming. I cut his seat belt off of him because his neck was wrapped around. They spun so much that his neck was under the seat belt the other way," says Kendall.
There has been no word yet on the condition of the teen or the driver.
