The problem with the Discovery Channel show is that they didn't offer any counter theories to the one that TIGHAR was putting forward. Heck, they didn't even question anything the TIGHAR team was saying. I don't know about you, but I thought I was watching the South Pacific version of Finding Bigfoot. For those of you who don't know, the TIGHAR theory is a "fringe" theory when it comes to Earhart and pretty much the only ones who buy it are TIGHAR and their funders.
Here are two pieces by Brian Dunning that offer a little different take on their theories and their "evidence".

Finding Amelia Earhart
Popular modern reports claim Amelia Earhart made it to an island and survived for a time. Might that be true?

As I went into great detail in my
Skeptoid episode about the fate of Amelia Earhart, she and navigator Fred Noonan disappeared in 1937 off Howland Island in the south Pacific when they ran out of fuel in the immediate vicinity of their destination. However, in today’s news, it is being widely reported that an expedition is underway to pursue new evidence via expensive underwater searches, that Earhart ended up instead as a castaway on distant Nikumaroro Island (then called Gardner Island). Money is indeed being spent on this expedition, apparently by the Discovery Channel, but that is where the fact ends. This alternate explanation for Earhart’s fate is almost certainly completely false, and exists only for the purpose of sensationalism at the expense of public intellect.
