That's a lot
"there were a grand total of 109 incidences of batteries on planes exploding, enflaming or just plain smoking"
So if you counted all batteries on and OFF planes exploding, enflaming or smoking, then it would be incredibly large!
Conversely if you counted all the deaths from foreign objects in orifices WHILE ON A PLANE, then that would be tiny by comparison to batteries exploding.
Seriously, that number is huge, far bigger than I would imagine and suggests a big problem with batteries.
