2016 Ford Superduty Looks Hot!

My first thought, when seeing the photo of the explosion mentioned, that it looked like Magnesium in the mix, too. But, if you look closely, all of the white particles are whole, not giving off any energy (heat or light). My guess is an air bag exploding in it's stored location and what the white stuff is are components of the dashboard. In any event, it's an instantaneous pressure release and not caused by aluminum reacting. I'm with T&P, it's something going off with stored pressure.
