Tip: compare the dust clouds with a(n) [artificial] volcanic eruption
Just before its destruction, molten steel was pouring out of the breaking points of the South Tower.
Little fountains of liquid metal, similar to discharges or little detonations were ejected from the facade.
When the South Tower collapsed, the spire turned for about 2.5 seconds in free fall.
The rotation velocity then decreased [free downward acceleration of fall] and stopped at an inclination angle of approx. 15°.
The model assumes the formation of a standing soliton (a superhot plasmic needle) that:
acted as locking bolt
pulverized the spire (after neutron radiation had weakened the structure)
“Conservation of angular momentum is the tendency of a rotating solid object to continue rotating at the same rate in the absence of torque.”
“Initially the block consisting of the top 30 stories of the tower acted as a solid object, and rotated about a fulcrum near the impact zone.”
“Although the fulcrum was the axis of rotation, the block had two types of momentum: the angular momentum of the block around its center of gravity, and the linear momentum of its center of gravity tilting away from the tower's vertical axis.”
“When the portion of the building below the collapse zone disintegrated, the block would preserve its angular momentum by continuing to rotate at the same rate.”
“But in reality, the rotation of the block rapidly decelerated as the downward plunge began. ”
The twin towers were destroyed as standing towers from top to bottom while dust clouds were shooting up from the ground and steam developed at the foundation.
During the disintegration of the South Tower, explosions shooting out of the facade far below the line of destruction could be observed.
An eruption-like behavior could obviously be observed for the South Tower.
During its disintegration, a clear separation between two different types of dust clouds was observed at the South Tower
The disintegration pattern resembled a water fountain.
The formation of the South Tower’s cloud stem was less distinctive than the one at the North Tower.
The aftermath of the explosion is overshadowed by a steel / concrete dust cloud that develops rapidly.
The suggested model gives a plausible explanation for the formation of a cloud stem.
The disintegration of the South Tower was accompanied by gas outbursts from below.
These gas outbursts took place just before the dust cloud reached the ground.
Standing steel structures remained to be visible during the disintegration of the tower.

@ 00:33: Byron Pitts: "As a fireball rolled towards us Mika grabbed her shoes, I grabbed her hand and we ran like hell..."
@ 01:07: "and the street below, caved in. The whole street caved in, you could see below the street. ...And at that point there was like fireballs coming up."
A few minutes before collapse molten steel was pouring out of the South Tower.
