A system for locating a debris field resulting from a plane crash comprises a plurality of low-power, battery operated electronic transponder tags, and at least one locator operative to the interrogate the tags to determine the location thereof. The tags are placed on or in an airplane in multiple locations, thereby enabling the locator to determine the location of a debris field in the event of a crash. The locator, which may be airborne, preferably reports tag positions for map display. The tags may be hermetically sealed to prevent water infiltration, and may be triggered to an active state in response to a large acceleration or always in an ON state. Tags placed on or in the airplane may be mounted in a manner to intentionally detach. The tags may further include a barometric pressure sensor, a shock sensor and/or an accurate time base to record the time of a crash.
