The fact that only about 3000 died was a miracle itself. We can't depend on miracles to save us.
“9/11 was an attempt to kill 50,000+ people.”
Lets not forget the visitors.
Some 50,000 people worked in the buildings, while another 200,000 visited or passed through each day.
And this was the second attempt. If the 1993 blast would of worked as plan when terrorists drove a truck packed with 1,100 lbs of explosives into the basement parking garage, the death toll would of been of much much worse. The blast was intended to topple one tower against the other bringing both down before anyone had a chance to escape. Thank God it did not go as plan.
If the 9/11 attack had come 30 minutes later and the planes had hit 15-20 stories lower, the death toll probably would have been 10-15 thousand.
