The passenger's seatbelt was buckled.

"When flight attendant C reached row 14, she saw that the head, upper torso, and arms of the passenger seated in 14A had been pulled outside the airplane through the window. The passenger’s seat belt was buckled. Flight attendant C grabbed onto the passenger and, with assistance from flight attendant A, tried to bring the passenger back into the airplane, but flight attendant A reported that they could not get the passenger back into the airplane by themselves because of the pressure and the altitude. Two male passengers (in seats 8D and 13D) offered to help; they were able to pull the passenger back into the airplane and laid the injured passenger across seats 14ABC."

RIP Jennifer Riordan.
