Ouch! The box is heavy but the fire truck was heavier im sure. Factor that in addition to it being at an angle with minimal bumper contact, with the fire truck, and that is why it looks so severe and possibly why the air bags did not deploy. IMHO.
Reminds me of my work van that was involved in a chain reaction crash, at highway speed, last february but not as severe. The front of the wan was so mangled that you could not determine where the bumper was. One day when the legal proceedings are over ill upload pictures of it. Im blessed to have walked away with a sprung ankle and fractured metacarpal. Wish everyone was as lucky that day.
