In your graphic you have misplaced the WTC towers. I have added them and the other WTC buildings on the attached revised graphic. 1 and 2 are the north and south towers respectively.
It looks like the "mushroom cloud" might be coming from 6WTC or 7WTC.
Also attached is a Fox News graphic I used as reference.
