There HAD to be enough resistance to cause debris to be blown around the site. That's a lot of wind to move a single ten thousand pound panel. At freefall speed, it would take nine seconds for roof to kiss sidewalk. Do your own counting. Compressed air, metallic elasticity, bending moments can't be avoided in any sort of collapse - even with explosives.
As for the step ladder analogy just drop your nuts on the floor. They are going to spread during their fall and land in a larger pattern than the size of the palm of your hand. Set up a half dozen pill bottles and I bet some that weren't directly under your nuts when you dropped then will be hit.
