If you watch to the end, you'll see a NASA shot showing the base of all three buildings, with building 7 being the hottest. That is the work of some fancy incendiary used as a corrosive, and I wouldn't be surprised if hydraulics were what brought down the center first.
We'd be interested to know why, kyle.
It was chance that saw WTC7 hit by debris from WTC1 and fires started there. The large debris could have missed (it nearly did) .... little damage, no fires.
Then what? WTC7 spontaneously collapses hours later for absolutely no reason? They go in and remove the 'fancy indendiaries' and 'hydraulics' because they're no longer needed?
As narratives go, the whole WTC7 demolition business doesn't have one.
(prediction - very shortly we'll be pointing out that shredders are a much more reliable and discreet way of destroying incriminating evidence than blowing up buildings).
