    Yes, that is the web site.

    I don't think that is correct. It was suggested/assumed that Amelia
    Earhart would have been annoyed by the popping sound of the patch 'oil
    canning'.  Gary could probably comment on this point.

    But that is backwards reasoning that presumes the conclusion.  They
    have a piece of scrap aluminum that they are trying to match with a
    field patch made to the Lockheed plane. The only thing known about
    this patch is the approximate dimensions.  If they could match the
    scrap piece by rivet holes along the periphery, that would be
    convincing.  But instead they have several rows of nicely spaced rivet
    holes in the center of their scrap piece.  They explain these extra
    holes by claiming that there must have been three internal stiffeners
    added to the patch.  It is certainly possible, but there isn't any
    evidence that the field patch included such stiffeners in those exact
    locations.  It is simply a convenient assumption made up by TIGHAR to
    fit their desired conclusion.

    I totally agree.  And that brings us to the linchpin of the argument.
    TIGHAR claims that the low quality Miami photo does indeed show these
    lines of rivet holes, and their subsequent chain of reasoning is
    almost completely based upon that finding.  I looked at what they
    published and I can't see them.  They assure their followers that the
    subreport on the image analysis is pending.  They did not want to
    publish it at this time because there is further forensic analysis to
    be done.
    Claiming a perfect finger print match and near certainty seems a bit
    premature, before the release of the key evidence.
