Todd Baur, who identified himself as the father of a passenger from the plane, told Philadelphia's NBC-10 television that a female passenger was injured when she was partially sucked into a window near the afflicted engine before being pulled back into the aircraft by other passengers.
Philadelphia Fire Department Commissioner Adam Thiel (TEAL') declined to release any additional details on the victim or their condition. To make matters worse, NBC Philadelphia is reporting that a passenger was almost sucked out of a window after shrapnel from the decimated engine broke it.
It depressurised the plane immediately and one passenger, a woman, was partially drawn out of the plane and was pulled back inwards by the other passengers.

The plane, a twin-engine Boeing 737 bound from NY to Dallas with 149 people aboard, made an emergency landing in Philadelphia just before noon as passengers breathing through oxygen masks that dropped from the ceiling said their prayers and braced for impact.
