You mean, you can watch that implosion and not realize that was a controlled demolition?
Yes, I can.
Just because it had some superficial resemblance to controlled demolition does not mean it was a controlled demolition.
I saw buildings falling into their own footprints due to entirely explicable physical forces and the initiating events that made the resulting collapse inevitable once one floor collapsed onto another already severely damaged floor, which then fell onto another.
I've talked about 911 with a contractor who was one of my business' clients whose business is controlled demolition. He has brought down some of the largest structures demolished in Northern California, including the 200 foot tall concrete Spreckels Sugar tower in Manteca. He said it was in no way a controlled demolition. It bore no signs of being one. None of the WTC building did.
You obviously have little comprehension of the months of advance work required before any controlled demolition will work, especially on a building of that size. That work cannot be accomplished without being noticed, especially preparing the demolition of that central core. There would have been drilling and jackhammering going on for months. . . and some of those holes they drilled would have been backfilled with concrete to direct the pre-placed shaped charges. Much of it would have to be done inside the offices of tenants, stripping wall finishes to the bare concrete to gain access to drill and place the charges. The demo-contractors would not have allowed any unauthorized radio or cellular phone transmissions anywhere in the building.
You've watched too many Hollywood movies with special effects building implosions where it is made to look easy and a few guys can do it with a knapsack of tiny C4 explosives in a few minutes. It's not at all easy and takes meticulous planning and preparation.
