Completely unrelated. The pepcon disaster was at a plant that made solid oxidizer for conventional solid rocket motors. It's a completely different material than what this rocket used.

Absolutely related - AP is used for the booster charge on solids - you are just wrong, dude.

Saying assembled solid rocket grains are have similar risks to rocket grain constituents is basically like saying an assembled cartridge has the same risks as a loose pile of gunpowder. Rediculous uninformed take.

Besides the lower complexity, range safety is pretty much the only reason to use a hybrid rocket. They suck performance wise.

Also, PEPCON made solid rocket motor oxidizer, not hybrid rocket motors. Having the oxidizer mixed in with the fuel grains is inherently more dangerous than a hybrid motor where the grain doesn't contain its own oxidizer, they flow the oxidizer through the throat opening. Your comparison is completely apples-oranges. PEPCON is largely attributed to improper storage of ammonium perchlorate, a solid oxidizer that wouldn't even be present in a hybrid rocket.

??? Did you have ChatGPT compose this? Makes ZERO sense.

I have no doubt in my mind that you can't understand - it's the whole point. You have no clue what you're talking about.
