The search for missing Malaysian Airlines Flight MH370 is back on. Here’s what to know

More than a decade ago, Malaysia Airlines Flight MH370 vanished without a trace, sparking one of aviation’s most baffling mysteries. Despite years of multinational searches, investigators still do not know exactly what happened to the plane or its 239 passengers and crew. On Wednesday, Malaysia’s government said American marine robotics company Ocean Infinity would resume a seabed hunt for the missing plane on Dec. 30, reigniting hopes that the plane might finally be found. A massive search in the southern Indian Ocean, where the jet is believed to have gone down, turned up almost nothing. Apart from a few small fragments that washed ashore, no bodies or large wreckage have ever been recovered. Here’s what we know about the deadly aviation tragedy.
