If you wonder what this is about, please see this 6 second video clip of the building collapse:
Yes, this 47 floor skyscraper came down in only 6 seconds, and the US goverment said it happened because of office fires. But engineers say never before has a steel frame building collapsed like this. I am no engineer, but I can tell this building is not collapsing due to fire. So I think they should reinvestigate the collapse of WTC-7. What do you think?
