Malaysia Flight 370: New signal sounds ‘just like’ one from a plane’s beacon
Tuesday is Day 32 since Malaysia Airlines Flight 370 disappeared. One hundred and thirty-three search missions have been carried out so far but they have been fruitless. Now, hope seems to rest on underwater pulses that an Australian navy ship has detected. Investigators hope the signals could be locator beacons from the plane's data recorders, but they're not sure yet.
