I like your analogy here. To be honest, this is an aspect I probably take for granted if I ever decide to talk to some truthers about this whole mess - the fact that they might not have the same background as me. What seems obvious, they may not have thought through.

Take a 25lb bag of sand. If I'm holding it in my arms, I'm stopping it falling right? That load on my arms is its static load. Now if I pass that to you and you take it, nothing bad happens because we do it in a way to make sure the dynamic load is minimized. But if I raise that bag 10 feet in the air and drop it
into your arms, are you going to try and catch it? Of course not, because you know the dynamic load is going to be enough to injure you.

However, to make your analogy more accurate to the situation, the person trying to catch the sandbag should have one arm tied behind their back.
The floor below the one that collapsed (and so on) had already had it's structural integrity partially compromised by the whole having an airplane crash into it and having a fire burn for hours thing...
