Side/window Air Bag problems of the 1999 Plymouth Breeze

The car went into a curve and would not steer out,then for no reason the driver side airbag deployed, knocking the driver out temporaily,causing the car to then proceed off the road, up onto a gaurdrail which then sent the car airborne onto the side of a concrete bridge which then flipped the car head-on into the conrete wall of the oncoming side of the bridge.
