Some Proofs of Demolition
The towers' concrete was pulverized in the air.
The steel superstructures of the towers provided
no more resistance to the falling rubble than air.
The volume of the dust clouds produced by the collapses
indicates heat energy far in excess of gravitation energy.
The South Tower's top shattered before falling
into intact structure.
Proofs 1 and 2 require only common sense.
Proof 3 uses basic thermodynamics,
and Proof 4 uses basic mechanics.
