2001 Ford Escape air bags problems

I was writing this for my sister who is no longer here. She drove a 2001 ford escape going 60 MPH down the highway. The people in front of her stopped and she rear ended them. Her car flipped several times and she was ejected. Although the state troopers said she wasn't wearing her seat belt she clearly had a 2" by 4" abrasion on her left shoulder exactly the size and location that her seat belt would have been. The SUV was completely destroyed, not a panel on it wasn't smashed - and yet the airbags didn't go off.

Tl* the contact owns a 2001 ford escape. While driving different speeds, the accelerator pedal became stuck. The contact placed the vehicle in neutral and depressed the brake pedal, which caused the vehicle to jerk and continue normal driving. The contact also stated that the passenger side air bag had bubbles and appeared as though it would explode. The failures were not diagnosed. The manufacturer was not made aware of the failures. The failure mileage was 163,000.
