How Demolition Charges Were Placed in WTC 1 AND 2: A Hypothesis

[Charles Drago]

Also, Charles, remember that:

1) All three buildings (WTC 1, 2, and 7) had been evacuated twice, floor by floor, in June and July of 2001, and:

2) Anyone with access to the elevator shafts would have been able to plant demolition charges in all three buildings.

I do remember.

And I would expand upon your second point: "[They] would have been able to plant demolition charges [and/or update, modify, and examine the condition of existing] demolition charges [and systems] in all three buildings."
