List of unrecovered flight recorders
Flight data recorders (FDRs) and cockpit voice recorders (CVRs) in commercial aircraft continuously record information and can provide key evidence in determining the causes of an aircraft loss. The greatest depth from which a flight recorder has been recovered is 16,000 feet (4,900 m): the CVR of South African Airways Flight 295.
Recovered recorders are not always able to definitively identify, however, the causes of an accident. Recorders successfully recovered can be too damaged to be read, or may have missing data caused by power loss, as with TWA Flight 800, American Airlines Flight 77 and Swissair Flight 111. In the bombing of TWA Flight 841 on 8 September 1974, neither the FDR nor CVR were recovered from the Ionian Sea, despite the locations being narrowed down through the use of the attached Underwater locator beacons (knows as "pingers").
