NTSB PROVIDING TECHNICAL ASSISTANCE
TO FBI INVESTIGATION

WASHINGTON, D.C. - The National Transportation Safety Board is providing
technical assistance to the Federal Bureau of Investigation, which is the
lead agency investigating the terrorist attacks of September 11.

At the request of the FBI, the Safety Board has sent investigators
with knowledge of aircraft structures and flight recorders to the crash
sites in New York, Pennsylvania and at the Pentagon. They are assisting in
the search for the cockpit voice recorders and flight data recorders - the
so-called "black boxes" - and helping to identify aircraft parts.

The NTSB has offered the use of its laboratories to read out any
recorders the FBI may find.

The Safety Board also dispatched its family affairs specialists to
New York and Pennsylvania to advise the FBI and the airlines on providing
federal services to the families of the victims of these crimes. Similar
assistance is being provided for the crash at the Pentagon.

As the crashes of the four airliners on Tuesday are criminal acts,
the FBI is the lead investigative agency and will release all information on
the progress of the investigation.
