Seriously, I recall several similar, if not as catastrophic building failures over the past several decades, a few here in the US; buildings on the East Coast have been known to spontaneously collapse, although usually due to some underlying event like an internal explosion, etc,; one possible cause I haven't heard mentioned is a sinkhole of some kind; Florida is well-known for its sink holes (no, it not a dig at Gov. DeSantis) and, in recent years, it seems as if they have been more frequent and more severe in size and effects; if there was a failure under the center(s) of the mass of the collapsed section(s) caused by a sudden collapse by a sink hole, the pancaking effect would be more explainable; from the photos and videos I have seen of the disaster site thus far, the floors (stories) rather 'neatly' piled upon each other, which gives almost n hope of finding anymore living residents; if the collapse had been more lateral (horizontal), there might have been areas created to possibly provide survival protections, but the motion was almost perfectly vertical, meaning those on each successively lower floor were crushed directly by the floors above them...
