Picture 3

Television image of an airliner creating a ball of fire as it hits one of the towers of the World Trade Center, September 11, 2001.

The aircraft crashed into Tower 2 (obscured) as Tower 1 burned after being hit minutes earlier by another hijacked airliner.

Both towers collapsed to the ground a short time later.

An aircraft was also crashed into the Pentagon near Washington this morning and another airliner crashed near Pittsburgh, Pennsylvania in an apparently related move.
