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.

Investigators are looking into how all 76 passengers and four crew members aboard Delta Air Lines Flight 4819 survived after the plane crash-landed in Toronto on Monday.

No one was killed but 18 of the 80 people aboard were injured when the aircraft flipped while landing during the flight from Minnesota to Canada.
