A flight attendant on board a Delta plane that crash-landed in Canada and flipped upside down claims an inexperienced pilot is to blame for the incident in a bombshell new lawsuit.

Vanessa Miles, 67, who worked for Delta's regional subsidiary Endeavor Air as a flight attendant, was traveling as a passenger on the regional aircraft to her next assignment when it crashed on February 17.

Endeavor Flight 4819 a crash-landed in Toronto from Minneapolis and burst into flames after flipping over and skidding on the tarmac.

Dozens were hospitalized but miraculously all 76 passengers and four crew members survived the horrific crash.

Now a lawsuit filed against both Delta Air Lines and Endeavor in federal court in Michigan on Monday claims the fiery crash was caused by, 'an inexperienced and inadequately trained pilot'.
