Q: Is there anyway to find out what the original 911 hijackers were doing at H-Hour minus four days? To create a detailed timeline for their activities leading up to their boarding their target planes?

You'll remember that a few posts ago, I referred to the month of September as the empty stillness between gunshots. Remember that stillness can be shattered and empty can....become....FULL in the blink of an eye.
