In this image made from TV, released by AMSA (Australia Maritime Safety Authority), a marker flare is deployed into the Indian Ocean from a Royal New Zealand Air Force (RNZAF) plane searching for debris from the missing Malaysian Airlines Flight 370, off the west coast of Australia, Friday March 28, 2014. Three weeks into the mystery of missing Flight 370, investigators are relying on newly analyzed satellite data to dictate their search field, and some potential flotsam has been photographed for assessment overnight, but the objects cannot be verified or discounted as being from MH370 until they are relocated and recovered by surface vessels.
