The disappearance of Malaysia Airlines Flight 370 demonstrated the limits of the contemporary flight recorder technology , namely how physical possession of the flight recorder device is necessary to help investigate the cause of an aircraft incident . Considering the advances of modern communication , technology commentators called for flight recorders to be supplemented or replaced by a system that provides " live streaming " of data from the aircraft to the ground . Furthermore , commentators called for the underwater locator beacon 's range and battery life to be extended , as well as the outfitting of civil aircraft with the deployable flight recorders typically used in military aircraft . Previous to MH370 , the investigators of the 2009 Air France Flight 447 urged to extend the battery life as " rapidly as possible " after the crash 's flight recorders went unrecovered for over a year
