I know how much steel and concrete are on each floor close enough to do a good momentum model on paper which shows the towers could fall in 12.08 seconds in one case. I can't help it if you are model challenged and unable after 7 years to understand what I understood on 911. I must of listened in class and I respect science; you clearly have disdain for the scientific method and it shows in your shoddy research and failed models. Self debunking nonsense is your best product, I enjoy each post were you confirm your contempt for science.
I see you treat your beliefs on 911 as a religious like faith based on lies, hearsay, sloppy research, minimal math, shoddy physics, poor models, fantasy ideas, and pure opinion based malarkey. Your models prove this as you can’t estimate after 7 years the weight of each floor already done for you by another 911Truth want to be person as pointed out here to save you time. You can’t do the simple research after 7 years but you can whine and make up excuses for your own failed ideas by blaming me on some false charges and failed delusion of yours.
No you are suppose to look at the aircraft impacts and start your study based on science no your opinions and common sense delusions. You just want to be a no plane person? A failed engineer and physics like 911Truth offers as experts who only have failed nut case ideas?
You can come real close to the mass involves, but you may have to work at in instead of whining online about it.
