What would that footprint be in shoe size considering that it was 16 acres?Now, each building crumbles into it's own footprint. Okay, so in the documented history of steel-structured skyscapers like the WTC towers...there has NEVER (I'm just letting you know, so you don't have to look it up) There has NEVER been a steel-structured skyscraper, that has COMPLETELY collapsed into it's footprint by virtue of a FIRE.
