Over the Indian Ocean, members of the Royal Australian Air Force are scratching their heads, looking for any trace of a missing Malaysia Airlines plane. Flight MH370 from Kuala Lumpur to Beijing disappeared weeks ago with more than 200 on board. It's presumed to have crashed west of Perth in one of the most remote locations on earth. Still, no tangible evidence of the missing plane. But four orange objects could be a lead says Flight Lieutenant Russell Adams.
