They believe the Malaysia Airlines jet flew 2,700 miles past Indonesia before crashing into the South Indian Ocean near to the coordinates of S34.2342 and E93.7875.
Victor Iannello, who assisted Australian officials during a previous search, said “there are better than even odds” that the missing passenger plane is within 100 nautical miles of the potential impact site.
