Flight 77 and crash it into the

Pennsylvania.
 In New York and Virginia, firefighters
and police officers rush to the scene
of the attacks.

of the World Trade Center collapsed.
 Fires caused by the planes full fuel

World trade centre collapse
Collapse of 7 World Trade
Center. As the North
Tower collapsed, heavy
debris hit 7 World Trade
Center, causing damage
to the south face of the
building and starting fires
that continued to burn
throughout the afternoon.
World trade centre collapse
There were 2996
people dead and
more than 6,000
injured on 9/11.
Everyone who
was working in
the buildings, on
the planes that
crashed into the
buildings and the
hijackers were in
great danger of
death. There were
246 people on the 4
planes that
crashed into the
building, and no-
one survived on
the planes. 2606
people died in the
Manhattan towers
and 125 at the
Pentagon.
55 military personnel were killed at the Pentagon. More than
90% of the people in the towers were higher than where the
impact was. There were many more casualties in the north
tower because it was struck first. The people in the south
tower started evacuating in fear of their lives.
HOW MANY CASUALTIES
WERE THERE?
World trade centre collapse
Rescue and recovery
The local, state, federal and global reaction to
the September 11 attacks on the World Trade
Centre was unprecedented.
The equally unsurpassed events of that day elicited
the largest response of local emergency and rescue
personnel to assist in the evacuation of the two
towers and also contributed to the largest loss of the
same personnel when the towers collapsed.
After the attacks, the media termed the World
Trade Centre site "Ground Zero", while rescue
personnel referred to it as "the Pile".
In the ensuing recovery and cleanup efforts,
personnel related to metalwork and construction
professions would descend on the site to offer their
services and remained until the site was cleared in
May 2002.
