– “[M]any eyewitnesses reported regular, rapid energetic events in sequence down the building, which cannot be explained by any of the four common types of explosion.”
Yep, you can see those events on most collapse videos, and they’re referred to in the NIST report. They are dusty air being ejected through the perimeter columns. The internal front of destruction of floor assemblies proceeded (from memory) at around four or five storeys per second, and nearly all that air had to be ejected. These would have happened – would have to have happened – whether explosives were used or not.
In fact, think about it. If these ejections had been caused by explosives, there would have to have been another descending front of ejections caused by the expelled air.
– “Many eyewitnesses clearly thought they were watching explosions destroy the Twin Towers.”
Well of course they did! Whose first thoughts would turn to ejected air in the few seconds of witnessing such a sudden, momentous event?
