We now apply this simple model to the WTC collapse. We assume that both WTC building collapses began with an upper block of n floors collapsing onto a series of lower floors as in the “domino effect”. We shall refer to this process as the first stage of collapse. For this stage, (see equation 1), we have an initial mass nmf falling onto the floor below and becoming mass (n+1)mf. This new, enlarged, block of floors descends with velocity v2= [n/(n+1)]v1 through a distance hf at which point it strikes the floor below and becomes mass (n+2)mf moving at velocity [n/(n+2)]v2, and so on. This implies a first stage collapse sequence for WTC 1: all floors from 110 to 96 (= 14 floors) collapse onto floor 95; all these floors collapse onto 94 93 92 and so on to 32 1; for WTC 2 all floors from 110 to 81 (= 29 floors) follow the same sequential process.
At the end of each of these collapse events we envision a second stage of collapse involving the destruction of the upper block of the WTC buildings: for WTC 1 the 97th floor, plus all floors above, collapse onto the pile of rubble topped by floor 96; this is followed by floor 98 (plus all floors above) collapsing onto floor 97 and so on. The 2nd stage sequence for WTC 1 ends with floor 110 collapsing on to all lower floors. For WTC 2 the 2nd stage involves floor 82 collapsing onto floor 81, followed by 83, 84, etc, collapsing on to the pile of rubble until floor 110 collapses onto all lower floors.

Your post was entirely unnecessary attack on my OP. The point of my OP is to question both government facts as well as non believers of the OS. Both rely on the same method at determining the rate in which free fall occurred. My OP points out that if my theory is true it means that the building fell faster than free fall, which means they were propelled or the air below acted as a suction effect.

That is right Misfit. What I propose is to calculate the rate in which the portion under the 15+ stories collapsed. I think the determination will be that it collapsed faster than the rate of free fall acceleration, which would point to demolition.
