The search continues for a missing Malaysian Airlines jetliner.
There are still no concrete answers as to what happened to the plane. It was carrying 239 passengers.
At least 43 ships and 39 civilian and military planes from several countries are aiding in the search. The search area covers more than 27,000 nautical miles.
Military officials say radar may have picked up the plane taking a left turn and flying hundreds of miles off course toward the Malacca Strait.
Malaysian officials say now they're not sure.
"There is a possibility this aircraft made a turn back, but we are not sure whether it is the same aircraft," said Malaysian Air Force Chief Rodzali Daud.
Malaysian authorities are now going through the professional records and personal lives of the pilot and co-pilot. So far, they say there were no warning signs indicating any kind of trouble.
