To me it didn't look anything like a controlled demolition. Controlled demolitions are usually from the bottom up, and you can clearly see it happening before the mass of the structure falls on it's own footprint. That was not evident with towers at all. In fact, it was pretty obvious that it was a top down collapse.
I'm not an engineer, so I don't know what words to use to describe the effects, but to me, it doesn't look anything like the controlled demolitions I've seen...
Good observation.
