that's the issue right now. this is an event that we have never had before. you can look at it, you can speculate how it happened, but at the end of the day, it will take us months. >> it will takes months. how do you even begin to do that? >> engineering is the way to go. and the way these buildings were built which is all the same ways. concrete piles. concrete reinforcement around the staircases and elevators, which is the spine of the building, and you can see how the building pancaked. so most people believe that there was a failure between the horizontal and the vertical. but that has to be looked at, that has to be junlgd, that has to be agreed upon. at the end of the day, the reason that the northeast corner is down and the southwest corner is still up, that's a mystery. you can see the vertical shaft holding it up, that's the spine. >> you call the vertical shaft the spine? >> most of the buildings here in florida are built in a similar matter, where the emergency staircases act as our sheer walls, that's what holds us up, our spines. and horizontal slabs is what pulls it in. >> i want to bring in kit in .
