Exactly 30 days after its disappearance, Malaysia Airlines Flight 370's fate remains a mystery. Over the weekend, authorities reported a potentially promising lead in the search for the black box: a U.S. Navy pinger locator towed by an Australian ship detected signals consistent with transmissions from aircraft black boxes.
And on Monday, Malaysia's transport minister would not rule out hope for survivors, saying "Miracles do happen."
What's next in the search? And what have we learned in the past month?
