Can you refute anything in that video?
Which video? If you mean Mitspa's video it's pretty simple, his video is a theory based on CGI models and other theories, its not actual proof. Aside from that the official NIST report admits they don't have evidence that the fire alone brought down WTC 7. They even admit the fire wasn't hot enough to bring the building down in such a manner. Now mind you Mitspa is on to something though. The fire would be enough to weaken the structure and when added to other factors could easily have brought WTC 7 down in its own footprint. Those other factors though you'll have to wait until tomorrow or until Mitspa digs them out of google lol.
EDIT: My bad for some reason thought Kenneth posted this lol.
