Ah, I didn’t make myself clear. I am and was absolutely convinced that you can’t free yourself once “plugged” unless very lucky. I was thinking about the bring sucked into pieces aspect. But it’s the same calculation I guess. How much force can human body structure take? I think 330kg static pressure wouldn’t rip you apart but when there is some movement involved there is some extra momentum. I think that could work. Or we increase the area. But then we don’t have the nice space movie effect of being sucked through a small slot.
