MoltenMetalFallingObject

On the left we are looking
at the South Tower of the WTC. Less than a minute before it starts to fall. A large blob of liquid material
with the color temperature of molten iron pours out near the North-East
corner of the building. At almost the same time a 20 foot long object is thrown from the opposite side of the building.

Tracking the horizontal motion
of the falling object we find that it was thrown outward
at about 12 m/sec. Or 27 miles/h. Some questions arise. Why are objects being laterally
ejected at high speed prior to the fall of the building? How is this event related to the simultaneous
high temperature melting event.

How are both of these related to
the onset of collapse 40 seconds later?.
