Good find. Seems to verify the pool deck area collapsed first. You can see the debris. Another video suggests there was time to get out. An 88 old woman made out of her 5th floor apartment as well as someone from the 11th floor that helped her.
Why did it take a week to get this out? And where is the video between the water pouring out and them seeing fire trucks. Looks cut. Collapse would be in between.
