Actually, there were several minutes of super loud “popping” as cracks opened up from the roof, downward, and the parking deck roof pieces fell down.
I am hearing this claim for the first time.
Source?
I keep repeating myself, but...
The only way a concrete deck building can pancake is if all the primary support columns fail at the same moment.
As of yesterday, there were ZERO support columns visible above the rubble pile, which is (was) only 25-30 feet high
What happened to the 90 feet of concrete support columns that used to be above the second and third floor?
Until proven otherwise - all of the columns anchored in the basement had to collapse at the same moment.
