SEPANG, Malaysia — A signaling system was disabled on the missing Malaysia Airlines jet before a pilot spoke to air traffic control without mentioning trouble, a senior Malaysian official said Sunday, reinforcing theories that one of the pilots may have been involved in diverting the plane.
With the increasing likelihood that Flight 370 was purposefully diverted and flown possibly thousands of miles from its planned route, Malaysian officials faced more questions about how the investigation, marked by days of contradictory government statements, might have ballooned into a global goose chase for information.
Prime Minister Najib Razak acknowledged Saturday that military radar and satellite data raised the possibility that the plane could have ended up somewhere in Indonesia, the southern Indian Ocean, or along a vast arc of territory from northern Laos across western China to Central Asia.
