Malaysia Airlines Flight 370 flew north of Indonesia and around Indonesian airspace in its journey to the southern Indian Ocean, according to a report from 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, a senior Malaysian government source told CNN.

According to the source, the plane may have purposely been flown along a route designed to avoid radar detection.
