Passengers aboard the Delta Air Lines plane that flipped onto its back after crash-landing in Toronto recalled the frightening incident.

Investigators probing Monday's Delta plane crash at Toronto Pearson International Airport are piecing together what caused the dramatic incident.

One passenger said he was “drenched with jet fuel” as the planed rolled upside down and another claimed the crash occurred due to the flight crew’s "inadequate training," according to the lawsuits.
