Australian navy teams detected signals consistent with the frequency emitted by flight data and cockpit voice recorders some 900 nautical miles northwest of Perth in the Indian Ocean over the weekend, a development characterized by authorities as the best lead yet in the search for the wreckage of Malaysia Airlines Flight 370.
