The mysteries surrounding the disappearance of Malaysia Airlines Flight 370, and the true identities of some of its passengers, are as deep as the southeast Asian waters where multinational search teams are searching for the jet. Navies from two of Malaysia's neighbors were pursuing new leads as Sunday turned into Monday in the region. Vietnam's navy has spotted a floating object about 80 kilometers (50 miles) southwest of Vietnam's Tho Chu Island, which is off the country's southwest coast in the Gulf of Thailand, Vietnam National Search and Rescue Committee spokesman Hung Nguyen told CNN. The object was spotted by a Vietnamese navy rescue aircraft at about 7:30 a.m. ET Sunday (6:30 p.m. local time). Because of the dark, the navy aircraft could not get close enough to identify the floating object and was recalled to base. Three search and rescue boats have since been deployed to that location.
