The first video appears fake. Regardless, like in many fires there were sounds that were loud from close range. There are many items that can potentially sound explosive in fires. When the planes hit, some of the elevators slammed to the basement which sounded loud from close range. The jumpers made a loud sound when they hit the ground. There are no explosives heard during any of the buildings collapses.
The second video has nothing to do with anything. Place a 25lb weight on your foot: what do you feel? - probably not much. Now drop the same weight from ceiling height. Now what do you feel? OK, dont do it. Youd regret it. The force on your foot when the weight is dropped is many times the force when the weight is placed.
Those buildings werent designed to withstand any force that is many times the normal force of the floors above. That would make them very expensive to build, and it would leave less room for the occupants. Once the collapse started, there was no way the building underneath could stop it.
