Physicist Steven Jones: “the Towers fall very rapidly to the ground, with the upper part falling nearly as rapidly as ejected debris which provide free-fall references . . . . Where is the delay that must be expected due to conservation of momentum---one of the foundational Laws of Physics? That is, as upper-falling floors strike lower floors---and intact steel support columns---the fall must be significantly impeded by the impacted mass. . . . [b]ut this is not the case. . . . How do the upper floors fall so quickly, then, and still conserve momentum in the collapsing buildings? The contradiction is ignored by FEMA, NIST and 9/11 Commission reports where conservation of momentum and the fall times were not analyzed”

Prove that is the speed they fell.

Except for the two 100+story buildings that fell right next to it.
