KaPow means the tube bubbled out of the slit before it popped - not a simple puncture where the tread and tube get cut at the same time.
Certainly not caused by too much pressure. Possibly some torn threads in the casing - or brittle threads if it's an old tire.
So you've probably got a pretty good gash in the rubber, and a pretty big rupture in the tube.
Probability of fixing this with sealant I'd put at about 1%.
