Malaysia Airlines Flight 370 flew north of Indonesia and around Indonesian airspace in its journey to the southern Indian Ocean, a senior Malaysian government source told CNN.
The conclusion was reached by investigators after reviewing radar track data from neighboring countries.
The plane did not fly over Indonesia or its airspace after making a westward turn in the South China Sea and flying across the Malaysian Peninsula, the source said.
According to the source, the plane may have purposely been flown along a route designed to avoid radar detection.
Flight 370: Search teams investigate sounds picked up in ocean
Search teams looking for Malaysia Airlines Flight 370 are investigating a number of sounds detected by ships in the southern Indian Ocean, authorities said Sunday, but it’s not yet clear if any of them are from the missing plane’s so-called black box.
A British Royal Navy vessel is on its way to an area where a Chinese ship reported picking up electronic signals twice, once on Friday and again on Saturday, said Angus Houston, the head of the Australian agency coordinating search operations.
And the Australian naval ship Ocean Shield, which has highly sophisticated equipment, is pursuing “an acoustic noise” that it detected in a different area, Houston said at a news conference.
He said the detections were “an important and encouraging lead,” but he cautioned that they be treated “carefully” as they haven’t been verified as being related to Flight 370.
