There is a good reason for not actuating the airbags - the airbag and actuator cost around £75 ($100) to replace, and are one of the likeliest parts to be salvaged from a wreck. On the other hand, from my memory of (British) explosives regulations, storing them on a shelf or in a box together would breach the regulations, while leaving them in the wrecks until needed would not. Incidentally, I am reliably informed that the airbags on European Fords will not actuate unless the seatbelt is being worn - belt and braces approach?

Spaw - if you like, I'll do you a dish of Pneu Farcie avec Amortisseurs Brules for dinner!
