If I may throw my two cents to the winds... Ok lets for the sake of argument, Captain Noonan isn't injured and the reports of post loss radio calls didnt say he was injured (and by the way, she was reportedly injured as well), then maybe he did inflate a raft or cut down a tree... with little or no equipment, water or poor food in 100+ heat, and maybe he did drag a two ton lifeboat to the beach, launch it and paddle it away to who knows where. Do we really think that he could have paddled, sailed or got out and pushed, ANYTHING away from that island and left a woman behind? hehehe... If Amelia was anything like MY wife he couldn't have set foot in anything that floats let alone paddle it away without bringing her with him! On the serious side, IF they made it to Niku, and IF the bones found were Amelias, and IF he built, inflated or otherwise created something to sail, Why didn't she go with him?
