Answer:
The human and economic costs of the attacks were horrendous. As of August 2016, six out of every 10
dead bodies in the twin Towers had not been identified. They were either completely burned or so
disfigured that their names could not be established with certainty.
Thousands of other New Yorkers, and the victims of the attack on the Pentagon, still suffer from their
injuries. The damage to buildings ran into billions of dollars. 15 years after 9/11, the construction of
three new World Trade Towers was still far from finished.
And throughout the shocked Western World, governments took unprecedented5 measures to prevent
more terrorist atrocities.
Air travel across the United States and Canada was almost completely suspended for three days; from
coast to coast, communities, sports clubs, and other organizations cancelled or postponed events that
could attract large crowds and offer targets for terrorists. Similar precautions were taken by some
European countries. In the United Kingdom, for instance, civilian aircraft were forbidden from flying
over London for several days after the attack.
The U.S. government was reorganized and put on emergency footing. The Congress created a
Department of Homeland Security (DHS) tasked with a huge mission: preventing terrorism disasters,
and managing border security, immigration, customs, and cybersecurity.
