It was designed to handle up to about 25 pounds of explosives according to the doc. They put 45 pounds in it and it did not contain the explosion.

I thought these carriers were basically a funnel that directed blasts straight up. But they mention “close the hatch;” I wonder if they amplified the destruction by using the giant pressure vessel they created.

Nobody asked “25 pounds of what?”

25 pounds of black powder is different from 25 pounds of TNT which itself pales in comparison to C4. These jackasses glanced at some box labels, figured everything was as powder-dense as ladyfingers and ALSO went way over design capacity for THAT assumption; idiot arrogance likely causing some senior nitwit to assume “these things are always over-designed because they think we’re idiots- let’s prove what this baby can really handle.”

Black powder is about 55% the power of TNT, C4 about 134% the power of TNT.

TNT and C4 have much higher velocities, but black powder actually has a higher density than either of them.

25lbs of TNT or equivilent that is how explosives are measured.

So say for C4 it would be rated for 18.51lbs. For BP it for be ~45.45lbs which they probably assumed since that is what they loaded. The 25 LBS is the rated MAX (though it probably has some designed in overages. But it wasn't BP and they didn't add in the detcord and other triggering explosives.
