TIGHAR has for decades been promoting that idea that a piece of Alclad sheeting it found on Nikumaroro, which it refers to as artifact 2-2-v-1 is a piece of Earhart's plane. Back in the 1990's Ric Gillespie of TIGHAR held a press conference proclaiming 2-2-v-1 as proof that Earhart wound up on Nikumaroro. Every now and then over the years 2-2-v-1 comes to the fore again at TIGHAR. Two or three years ago, TIGHAR claimed that a photo of Earhart's plane taken in Miami showed a temporary window patch on Earhart's Electra that matched the rivet pattern on 2-2-V-1. TIGHAR promised that a report on that match, but never produced it. This year, TIGHAR announced it was analyzing film footage of Earhart's plane in New Guinea looking for that same rivet pattern. Nothing since that announcement.
What TIGHAR didn't announce is that in 2017 a staffer at the New England Air Museum (NEAM) informed Ric Gillespie that the rivet pattern on 2-2-v-1 matches a section of the upper wing of a C-47, a plane type that crashed on an island near Nikumaroro. See:
https://istigharartifact2-2-v-1apieceof ... asite.com/TIGHAR did not acknowledge the NEAM match for over 2 years, and when it finally did it simply dismissed the matter with the statement 'not even close'. When I read the above report the match looks pretty good to me.
