I know it is off topic a little but I have seen or heard of: ( after the fact of course)
a green gas bottle blow out ( break the glass , not exploding the glass, but luanching into it)a car winsheild,
a can of soda blow and launch the can like a bottle rocket round and round the car hitting glass, personal stuff and spray sticky soda all over
I have seen several bic lighters swell up then blow up like mini grenades
anything under pressure even not combustable can and does bad things when in the SUN or when too hot, shit even whip cream could blow and shoot out the tip ( fail safe) and shoot around like a whipcrem spitting rocket can.....
OH altutude can do it too but you'll never see it now with the new travel restrictions on what we can carry but back back wen I got home to find wife's lotions and my shaving cream that had gone off while in the air messing up that garment bag real good........
