Relatives of passengers onboard Malaysia Airlines Flight MH370 pray during a candlelight vigil in the early morning, at Lido Hotel, in Beijing April 8, 2014, after a month of searching for the missing Malaysia Flight 370. An Australian ship searching for a missing Malaysia Airlines jetliner has picked up signals consistent with the beacons from aircraft black box recorders, in what search officials said on Monday was the most promising lead yet in the month-long hunt.
