2007 Ford Focus engine problems

My car was in a single vehicle accident as we hit a power pole head on going at least 50 MPH. I wasn't the driver. At impact both the driver and myself had our heads crash into the dashboard. The driver smashed his head into the steering wheel and I hit the area above the glove box. My head also hit the passenger door. The car caught on fire and burned completely to the ground. My concerns are that with an accident of that magnitude, not a single airbag deployed in the car.

My son was involved in a 4 car accident, he was the third car in the accident. The first car claims that another car ahead of her stopped short and to avoid hitting the car she slammed on the brakes causing the second car to hit her in the back. My son couldn't stop immediately so he hit the second car in the back., then the fourth car hit [xxx] on the back with enough force to dent the whole hood and broke the radiator and cave the front bumper into the motor. The car is not drivable.
