It couldn't have been a 'controlled demolition'. Ask your dad how much explosives would have been required to bring them down and you'll find that the logistics of implanting that much would be impossible to hide and would have left far more evidence behind than the materials that are found in common building materials and office machines.
Also, ask your dad how far away he had to be when the explosives were detonated to avoid losing his hearing.
I said Building 7, buddy.
You're trynna tell me this is how a building collapses from a fire? the same way as it would from a controlled demolition?
and lol okay.. but my dad can't hear for shyt. his "indoor" voice, is pretty much yelling.
