Ever seen a Volkswagen magnesium engine block burning? Real neat, Real hot.
Sat behind a Volkswagen 410(I think) wagon while it burned up next to route
95 one day near the Philly Airport about 15 years back. All I could do was
direct traffic away from it while waiting for the fire department. (I was a
volunteer firefighter at the time- so I stayed back, and controlled traffic)
Started in back- whole car went to the ground...

Never been too fond of magnesium bits in cars after that.
