Two passengers are suing Delta Air Lines after a plane overturned during a crash landing at Toronto Pearson International Airport, injuring 21 people. The aircraft, arriving from Minneapolis-St. Paul International Airport, burst into flames before flipping upside down on the tarmac.

Texas resident Marthinus Lourens filed a lawsuit Thursday, claiming he was “drenched with jet fuel” as the plane flipped. His attorney, Andres Pereira, stated that Lourens fell onto the ceiling after unbuckling his seatbelt and had to help open the cabin door when the flight attendant struggled. The lawsuit details injuries to his head, neck, back, knees, and face, as well as the trauma of assisting fellow passengers despite his condition.

On Friday, Minneapolis resident Hannah Krebs also sued, alleging “gross negligence and recklessness” by Delta’s flight crew, along with “inadequate training and supervision.” Her attorney, Jim Brauchle, called the crash a preventable accident, stating that passengers’ lives were “forever changed.” According to the lawsuit, Krebs was violently thrown inside the cabin and suffered serious injuries and emotional distress.

The Transportation Safety Board of Canada is investigating the incident, with assistance from the U.S. National Transportation Safety Board. Delta has not commented on the lawsuits but issued a statement defending the flight crew’s qualifications and FAA certification.

Both lawsuits, filed in U.S. federal courts in Georgia and Minnesota, cite the Montreal Convention, which allows passengers to sue in their home country. The legal action follows Delta’s offer of $30,000 to each of the 76 passengers, which the airline says comes with no obligations. Delta also confirmed that all injured passengers had been released from the hospital.
