The "in its own footprint" is classic failure.
It means you have no facts to support your fantasy.
You bring up experiments for steel frame buildings, WTC 1, 2 and 7 were not like the experiment, they were real events, not tests. The experiments you present by google knowledge, do not say WTC 1, 2, and 7 can't collapse, and you can't use the report to make up lies about 911. You googled up the experiments used by 911 truth to fool the gullible. If you had something you would do a paper to prove your point. Yet, you never looked up the real reports, or did you?
You repeat failed claims googled up, and adopt them out of ignorance, like saying, "in its own footprint". What does it mean? You can't figure out 911 after 12 years, so you repeat failed junk.
You can't defend any of the 24 hard facts with evidence? Why not?
The " in its own footprint" is a red flag of woo. Means 911 truth has no evidence, only failed slogans of 911 truth. 12 years of the movement of fantasy, idiotic lies, and nonsense. 911 truth = failure. You will need evidence to change that fact.
