You can see demolition squibs all over the place on the towers as they are falling. This is evidence of explosions I would say. You do realize that the fires were confined to a small number of floors don't you? The compounds used were thermite and nano- thermite, not conventional demolition explosives. The huge dust cloud you see from the collapse is called pyroclastic flow, caused by controlled demolition, which is the only explanation for pulverized concrete. The buildings were designed specifically to withstand impact from a jet, and designed so that if something catastrophic did happen, then the entire complex wouldn't collapse, but break off. How do explain the presence of thermite in the rubble? How do you explain Larry Silverstein saying they went ahead and "pulled" building 7? He admitted it was a controlled demolition on camera. Why was that building wired for controlled demolition? You really need to research the topic a bit more.
What you really can see there, is air bursting out from the easiest way, while collapse rise the pressure in the rooms. There is 4000 square meters of space in every room, room hight is at least 3 meters, so do you math. How many cubic meters of air there is in each room? When collapse presses floors toward each other, air between has to go somewhere. Furthermore, speed of those bursts is somewhere of the region 400-600 m/s, while slowest explosives are twise as fast.
And where is the sound? Where is the columns, cutted by the explosions? There is no such thing in ruins. If there would be some signs of explosion in the ruins, I bet that some foil hat would be pointing them out with pleasure. Have you seen one? No, because there isn't one. And try to explain why only few windows were broken, while there has to be tons of explosives detonated in that tower? Laws of physics demands that where is an explosion, there is a shock wave, and with that amount of explosives, it would be big. It would blow out all windows, not only few. This you don't see in demolition videos, because they usually take the windows away before detonation to prevent any flying glass.
