Again, as turtle pointed out, aluminum as most know it is stable and
does NOT burn easily. It will if the right circumstances are in place

I'm not a chemistry wizard, just a dumb fireman. It's my dumb fireman's guess that the explosive shower of sparks was caused by SRS components cooking off like Turtle thought, or possibly magnesium components. Magnesium burns spectacularly, as any firefighter who's attempted to extinguish a burning old-style VW engine block will attest.
