Like we've said, there was really a lot of good information in there, so it's unfortunate that the one thing they publicized so dramatically was discredited immediately. In a sense, it discredits the rest of the documentary.
If the internet and news media were going to freak out over a photo relating to Amelia Earhart, they need to freak out over the so-called "Bevington Object", which shows quite clearly an Electra landing gear wheel, or something extraordinarily similar to it, stuck in a reef on Gardner Island in October 1937, just 3 months after her disappearance.
The State Department was so intrigued by it that they got involved and three different photo analysts within the State Department stated with near certainty that the object is an Electra landing gear. There's zero conceivable reason that should be there on a tiny deserted island other than it being a piece of Earhart's plane. The Electra model was only two years old at that point and hers was almost certainly the only one to fly within 3,000 miles of that place at that time and unquestionably was the only one that had crashed in the Pacific up to that point.
The thought is that it popped off during the rough landing. Electra gear were prone to do this. They had a design flaw that wasn't corrected until later models. In fact, Amelia herself had an issue with this wheel coming off during an incident in Hawaii:
So the obvious thing to do is just go to where that object was pictured and search around the sea floor with submersibles to find some wreckage where her plane would have gotten washed off the reef (which they suspect would have occurred in just a few days). Unfortunately, the last two expeditions that have gone out to that location with submersibles have been totally stymied by the fact that A) after like 150 yards, the reef drops off into an abyss that goes down to like 17,000 feet, which is deeper than Titanic, and B) the underwater reef before the drop is so jagged and has so many tunnels and passages that getting submersibles to snoop around in there is almost impossible.
