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. News media should direct questions on this investigation to the FBI's press office at (202) 324-3691.
