By Siva Govindasamy and Nguyen Phuong Linh KUALA LUMPUR/PHU QUOC ISLAND, Vietnam (Reuters) - Officials investigating the disappearance of a Malaysia Airlines jetliner with 239 people on board suspect it may have disintegrated in mid-flight, a senior source said on Sunday, as Vietnam reported a possible sighting of wreckage from the plane. International police agency Interpol confirmed that at least two passports recorded in its database as lost or stolen were used by passengers on the flight, raising suspicions of foul play. Malaysia's air force chief said the Beijing-bound airliner may have turned back from its scheduled route before it vanished from radar screens. "The fact that we are unable to find any debris so far appears to indicate that the aircraft is likely to have disintegrated at around 35,000 feet," a source involved in the investigations in Malaysia told Reuters.
