Feng Zhishang cries as family members mark the birthday of his son Feng Dong, a passenger on board the Malaysia Airlines Flight 370 at a hotel where relatives gather to wait for news of the missing plane in Beijing, China, Tuesday, April 8, 2014. Search crews have failed to relocate faint sounds heard deep in the Indian Ocean, possibly from the missing Malaysian jetliner's black boxes whose batteries are at the end of their life.
