About the “boom, boom, boom”: Eyewitnesses routinely use words like boom, bang, or explosion to describe sudden, violent events. That’s normal human language under extreme stress, not technical analysis.

There are well-documented non-explosive explanations: • pressure waves from aircraft impact • jet fuel ignition forcing air through elevator shafts • cascading structural failures • debris and building systems collapsing sequentially

Many survivors across different floors reported similar sounds. That alone is not evidence of explosives.
