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.

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.

Ed Bastian, the CEO of Delta Air Lines, spoke exclusively to "CBS Mornings" about the frightening Toronto plane crash investigation, the experience of the crew on board the plane and aviation safety.
