The 'Black Box' .The Black Box Flight Recorder is part of modern aircraft equipment as we still have air crashes. The other side of the flight data recorder is the flight deck voice recorder.

Nothing is waterproof, especially considering the high stresses involved in an airplane accident. The flight data recorder is water resistant. It is also designed to minimize the probability of data loss even if it does get wet internally.
The black boxes are two separate devices, the Cockpit Voice Recorder (CVR) and the Flight Data Recorder (FDR) Old CVRs recorded thirty minutes of sound, new data replacing old data. New CVRs record two hours of sound. FDRs can record 17-25 hours of data.
