A simple question - what laws of physics have been suspended and how exactly?
The two 110 skyscrapers took no more than 11seconds to completely fall which is almost the speed of a free fall collapse.
A primary three schoolkid blessed with a little common sense can easily determine that the lower section of 80 structurally sound floors would have provided MASSIVE resistance to any potential pan caked collapse. It would take minutes not a second off free fall speed dah. The symmetrical collapse of Building 7 again in close to free fall proves beyond any shadow of a doubt explosives were used.
Oh wow, now I understand your mistake; you just don't understrand the way buildings can collapse, and you have no understanding of the time frame in which they can do so.
It is just completely and utterly wrong to say that it would take minutes to collapse sound floors. This was demonstrated in, for example, the L'Ambiance collapse, which occurred in about five seconds - just twice the free-fall speed. Similarly, in the Hyatt Regency walkway collapse, the walkways fell too quickly for people to get off them or under them - it took nothing like "minutes". Singapore's Hotel New World, a smaller building, collapsed within about 30 seconds. The Plasco Building collapsed in seconds; watch it from 39 seconds to about 46 seconds here;
See it from 22 seconds here;
Here's another collapse of a skyscraper, in seconds;

Once the upper floors start falling, they strike the lower floors at velocity. As Newton told us, the force increases by the square of the velocity. The falling floors therefore create much higher loads on the lower floors than if the upper floors were still stuck where they should be. This extra load is too great for the lower floor, which then collapses itself, and so on in a chain reaction of progressive collapse.
This is incredibly basic - just try hitting something and you will find that a moving object creates more force than a stationary object. Surely you must have noticed this? If not, I wonder how you actually manage to hammer a nail in.
