They disappeared without a trace. Two years after Malaysia Airlines flight 370 vanished en route from Kuala Lumpur to Beijing with 239 aboard, loved ones still don’t have closure. Investigators released a report today, noting that they remain “hopeful” the plane will be found. They’re searching a 46,000 square mile area, but so far the $133 million effort has netted just a single confirmed piece of debris. Many families want the search to continue until they have answers, but the painstaking effort will likely be suspended in June.
