The search is still on for wreckage from Malaysia Airlines flight MH370, which disappeared from radar south of Vietnam early Saturday morning carrying 239 passengers and crew, South China Morning Post reported. Two-thirds of the passengers were from China. Several potential crash sites have been identified, including an oil slick and other debris but officials have yet to positively identify the Boeing 777. The cause of the crash remains a mystery. The Malaysian military says the plane may have turned around just before disappearing. Two people boarded the flight using stolen passports and Malaysian officials have not ruled out the role of terrorism in the incident.
