 But we do know that there's a bunch of charges in the motor of the rocket, and they're supposed to go off sequentially. So one, two, three, four, five, six. It slowly builds pressure. It gets forced through the venturi, and that's what generates the propulsion, I guess, out the other side. Something happened, and it went number one, and then like two through whatever's left all at once. And the tube couldn't handle that, and so it just exploded. It essentially became a pipe bomb.
