How about multiple ejectable tubes(wing tips, tail and nose locations)that record flight and voice data and are ejected if an explosion or structural failure is detected or if the speed and trajectory indicates the plane will impact the ground. Eject with a small parachute and are made to float, along with a homing beacon, flashing LEDs. And capability to transmits the data to a satellite if possible or maybe even remotely to a surface ship or search team without physically finding the tube.
