Shit happens, and its not worth destroying lives over that. Airline gets people to where they need to be and people carry on.

Now if they took a clearly defective (puffy) battery on board, we could have that discussion, but there's no point in getting angry at someone who cant realistically prevent said shit from happening.

Won't someone think of the airlines?

Even a “good” battery can develop an internal short circuit from dendrite growth.

You could require the more resilient chemistries (but ones like iron phosphate output even worse gases). But this isn’t something you can 100% fix right now.

I don’t know if Samsung still x-rays phone batteries even.
