John Nelson is one of the 80 people who miraculously survived the disaster aboard Delta Flight 4819 that left 18 people injured.

Speaking to CNN, Nelson said the runways at the Canadian airport were in a "weird condition."

"It was a typical flight from Minneapolis to Toronto," he told the outlet. "And we were coming in, and I did notice the winds were super gusty. The snow had kinda blown over the runways. So coming it was routine but it was noticeable that the runways were in kind of a weird condition."
