Plane missing since March 2014 is aviation’s biggest mystery. Malaysia Airlines Flight 370, missing since 2014, was probably steered off course deliberately and flown to the southern Indian Ocean, according to the Malaysian government’s safety report into the disaster. Experts mapped the Boeing 777’s course only after picking through hourly data hookups with a satellite. Extensive sonar searches of remote waters off Australia’s west coast failed to locate the wreckage. Monday’s report didn’t support either theory explicitly, but struggled to come up with a mechanical explanation for the aircraft’s deviations. A few pieces of wreckage from MH370 did wash up in Africa but no bodies have ever been recovered.
