The National Transportation Safety Board (NTSB) deals with all modes of travel safety including aviation, highway, sea, and rail. The NTSB is charged with investigating every civil aviation accident in the United States as well as all other significant accidents by rail, highway, and sea. Also the NTSB investigates all airline crashes in which a US manufactured aircraft is involved. From this investigation the NTSB determines the probable cause of the accident.
The NTSB maintains a database of civil aviation accidents and conducts research on safety and travel. The NTSB is not part of the DOT. The NTSB has issued nearly 12,000 recommendations to the travel provider industry and maintains a most wanted list for safety improvements at www.ntsb.gov/recs/mostwanted/index.htm.
The State Department and the National Transportation Safety Board, as described in Wallman v. Tower Air, Inc., 189 F.R.D. 566, N.D.Cal.,1999, requires passenger lists and contact lists to be collected by airlines for the purpose of enabling these agencies to reach family members of passengers who have been seriously injured or killed in a plane crash.
