Are they on the right track? The discovery this week of a flaperon, later “confirmed” by Malaysian authorities to be part of the missing aircraft, breathed life back into the 17-month-long search. But the Australian Transportation Safety Bureau has announced that it’s continuing its seafloor search thousands of miles away in the southern Indian Ocean. Floating debris, in other words, says little about the wreckage’s true location and is less likely to provide answers. Without more to go on, searchers must continue their needle-in-a-haystack mission.
