Power with Control
Now I'm going to take my speculation a little bit further here. Y'all remember that fake Volkswagen commercial back in the day that was never officially aired should a guy setting off suicide vest inside of golf and it was just puff and noise. Nothing else happened.
My speculation is that the steel outer panels of that truck kept things from being worse. I'm also going to go a little bit further out of the limb and say I don't think the main pack ever caught on fire.
Let me emphasize I'm quite sure this was not what explosive experts would consider a "real" explosive device, not a high order detonation. I'm going to bet it was a bunch of cobbled together fireworks.
