NEW
YORKBarely half an hour before the south tower of the World Trade
Center collapsed at 9:59 a.m. on Sept. 11, 2001, none of the fire chiefs
briefing the mayor and police commissioner at a meeting on a nearby street
expressed concern that the 110-story building was in danger of falling, the
staff of the 9/11 investigating commission said in a report issued Tuesday.
.
"None of the chiefs present believed a
total collapse of either tower was possible," the report said, recounting the
impromptu meeting that occurred at 9:20 a.m. Only after Mayor Rudolph Giuliani
left did one senior chief present "articulate his concern that upper floors
could begin to collapse in a few hours," the report added.
.
"And so he said that firefighters should
not ascend above floors in the 60s." The findings were made public as the
independent, bipartisan commission created by Congress began two days of
hearings in Manhattan in advance of its final report, due in July.
.
Tuesday's report, one of more than a
dozen already made public by the 10-member commission, was read aloud at the
televised hearing, along with videotaped interviews of witnesses and officials
quoted in the report and graphic scenes from the disaster. Many family members
of 9/11 victims were in the audience at the New School University.
.
The commission staff said the purpose of
this report was only to offer a "reliable summary of what happened" on Sept. 11
without "much commentary." A follow-up report on Wednesday will "offer more
analysis and suggest some lessons that emerge for the future."
.
Much of the information released Tuesday
has been previously reported. The commission staff said: Rescue operations were
hampered by flawed radio communications systems or an inability to operate them
properly. In one case, a radio relay device, called a repeater, that was
intended to boost radio signals in the high-rise trade center complex, was
thought to be inoperative; in fact, the fire chief who had tested it in the
north tower failed to push one of two needed buttons.
.
"When he could not communicate," the
report said, "he concluded that the system was down. The system was working,
however, and was used subsequently by firefighters in the south tower." Partly
because they lacked comprehensive radio communications with firefighters deep
inside the building, the commission said, "the chiefs in the north tower were
forced to make decisions based on little or no information."
.
Although firefighters, police officers
and other "first responders" performed heroically, often at the cost of their
lives, interdepartment rivalries, especially between the police and fire
departments, added to the confusion over what has happening and how to deal with
it.
.
Although the administration of Mayor
Rudolph Giuliani issued a directive in July 2001 intended to eliminate potential
conflict among emergency agencies, each department "considered itself
operationally autonomous," the report said.
.
The confusion, agency conflicts and radio
problems not only kept many tenants from leaving the towers, but also led to
many police officers and firefighters entering or staying in the buildings even
after superiors had decided that the fires could not be fought or that everyone,
including rescue workers, should evacuate.
.
After the first hijacked airliner struck
the north tower at 8:46 a.m., conflicting information was given to tenants in
both towers about the dangers they faced and whether and when they should
evacuate. Public address systems were damaged by the successive impacts to each
building, and announcements that did get heard were sometimes erroneous or
confusing.
.
"All the emergency officials that morning
quickly judged that the north tower should be evacuated," the commission staff
said. "The acting fire director in the north tower immediately ordered everyone
to evacuate the building, but the public address system was damaged and no one
apparently heard the announcement."
.
People who sought information from
emergency telephone operators fared no better. The report said, "911 operators
and FDNY dispatchers had no information about either the location or magnitude
of the impact zone and were therefore unable to provide information as
fundamental as whether callers were above or below the fire."
.
Many people in the south tower "were
unaware initially of what happened in the other tower," the report said. "The
evacuation standard operating procedures did not provide a specific protocol for
when to evacuate one tower in the event of a major explosion in the other."
.
"According to one fire chief," the report
said, "it was unimaginable, 'beyond our consciousness,' that another plane might
hit the adjacent tower." As a result, officials initially thought the wiser
course was for people in the south tower to "stay in place" - standard procedure
for conventional high-rise fires for occupants not in the immediate vicinity of
smoke and flame.
.
"Indeed, evacuees in the sky lobbies and
the main lobby were advised by building personnel to return to their offices,"
the report said in recounting the confusion in the south tower from the time the
first plane struck the north tower to the time the second plane struck the south
tower 17 minutes later. "As a result of the announcement, many civilians in the
south tower remained on their floors. Others reversed their evacuation and went
back up."
.
By 9:02 a.m. officials decided that the
south tower should be evacuated as well, which its tenants were told via public
address system. "One minute later," the report noted, "a plane hit the south
tower."
