The Australian maritime agency warned the images may not be related to the aircraft, but one aviation analyst said Australian Prime Minister Tony Abbott likely would not have announced the discovery to the the House of Representatives in Canberra without being reasonably sure of their find.

“There have been so many false leads and so many starts and changes and then backtracking in the investigation,” said Mary Schiavo, a CNN aviation analyst and former inspector general for the U.S. Department of Transportation. “He wouldn’t have come forward and said if they weren’t fairly certain.”





But officials cautioned that there were no guarantees that the objects now being investigated would prove to be from the missing plane.
