However, TIGHAR.s track record isn't so good...an announcement of " tantalizing evidence" precedes a huge fund-raising drive, and the "evidence" turns out to be sheer speculation, ie: "human bones" that turn out to be turtle bones, etc.
There are other groups, with other theories just as valid, that simply don't have the PT Barnum PR talent that TIGHAR has...I hope its one of them that discovers the plane. One of the more interesting is an Australian(?) group that discovered WW2 records from a scouting patrol in jungle on New Guinea...the patrol discovered a crashed twin-engine aircraft that had been there a while (not a recent war crash). The site was over-grown, preventing a positive ID, but an engine model number was recorded that was not used for any military or cargo planes during the war. It corresponded to the engines used on Earhardt's plane, but no Electras were in commercial service in the area at the time. The group is still seeking funding to re-locate the crash site, which is in dense jungle.
