Jeffrey thinks his ROOSD can begin right away but it can't as the floors could take 29 million lbs. of force, which is a static load of about five additional full floors with their live load. The dynamic load of one floor assembly would be nowhere near 5g's so ROOSD needs to wait until a sufficient number of floors have broken loose and gained momentum.
Can't have a one story column disappearance... it would be 3 and the core above would drop causing more than 6 floors to break free and drop and no I don't think it would arrest.
And no I don't think the tower would stand with one floor of columns instantly vaporized. And yes a floor can support one or two as additional floors slabs as static load...dynamic... not so sure.
