Response to You didnt post and run, because I looked up info to point out your mistake.
Don't boil out a huge mushroom-shaped cloud of debris from the top ... nor do they eject material sideways. They just crumple straight down and fall over to one side or the other, carrying any dust that's created, down with the momentum of the fall. That should be pretty simple to understand.
