Australian Prime Minister Tony Abbott said there is a "high degree of confidence" that pings picked up in the hunt for the wreckage of Malaysia Airlines Flight 370 are from the jet's black boxes, NBC New reported. But Abbott stressed the fact that if the pings are from the missing flight, they are deep in the ocean and getting to them will be difficult. "Trying to locate anything four and a half kilometers beneath the surface of the ocean about 1,000 kilometers from land is a massive, massive task," he said.
