The first generation air bags were the worse. I worked at the port in Washington and worked on the new import cars that came off the ships and if the cars were damaged to much we would blow the air bags pull the gas tanks and take the car to the crusher. I did lots that way and remember we had 50 at one time we destroyed. We blew the air bags with a 9 volt battery from a distance and would about rip the windshield right out of the cars. Defiantly shook the hell out of them.
