KUALA LUMPUR -- A Malaysian police investigation into the pilots of the missing Malaysian jet might turn up nothing, the force's chief said Wednesday, while the head of the international search effort also acknowledged that an air hunt to spot wreckage on the surface of the southern Indian Ocean was not certain of success.
The statements underscored the lack of knowledge authorities have about what happened on Flight 370 and where it may have ended, and point to a scenario that becomes more likely with every passing day -- that the fate of the Boeing 777 its 239 passengers and crew might remain a mystery forever.
The plane disappeared March 8 on a flight to Beijing from Kuala Lumpur after its transponders, which make the plane visible to commercial radar, were shut off. Military radar picked it up the jet just under an hour later, on the other side of the Malay peninsula. Authorities say until then its "movements were consistent with deliberate action by someone on the plane" but have not ruled out anything, including mechanical error. (AP)
