Flight data recorders (FDRs) and cockpit voice recorders (CVRs) in commercial airplanes continuously record information and can be immensely helpful to determine the cause of a crash. The deepest a flight recorder has been recovered was the case of South African Airways Flight 295, where the cockpit voice recorder was recovered 16,000 feet (4,900 m) under the ocean.[1] However, there are many cases where recovered recorders did not definitively identify the cause of a crash. Recorders may be recovered, but too damaged to read or have blanks, like in TWA Flight 800 or Swissair Flight 111, after power is cut off.
