Malaysia Airlines Flight 370 report leaves families in dark 4 years on

Investigators probing the disappearance of Malaysia Airlines Flight 370 found no fault with the pilots or aircraft in Malaysia’s most comprehensive report yet into one of the world’s biggest aviation mysteries. But they had no explanation for what happened to the plane and the 239 people on board when it vanished about 4 years ago, and didn’t rule out the possibility of “unlawful interference” of the flight—though no terrorist groups have claimed responsibility. The report, released Monday said air-traffic controllers didn’t follow procedures and failed to watch radar displays as required. It said they also delayed activating emergency processes, which in turn delayed starting search-and-rescue operations. The leader of the investigative team said the report wasn’t final and conclusive given the plane’s wreckage hasn’t been found. <br/>
