According to Rhode Island engineer John D. Jarrell, one of the experts retained by Mellon, the objects are consistent with parts of Earhart's long-lost aircraft.
"In the absence of an alternative explanation for the source of those objects, we conclude that they are likely to have originated from Earhart's Electra," Jarrell wrote.
But both photogrammetrist James I. Ebert, an expert in photo analysis, digital mapping technologies and image processing, and Les Kaufman, a professor of biology at the Boston University Marine Program, disagree.
"The methods used to construct, rotate, scale and superimpose outlines of known plane parts upon objects seen in the video were effortful and clever. However, I did not find the demonstration convincing," Kaufman wrote.
"All that I could make out unambiguously on the video, even after the powerful suggestions brought forward by the superimposed diagrams, were two pieces of rope of different gauge, a circular piece of wire, a few other pieces that could conceivably be man-made debris, and a very great deal of largely unconsolidated carbonate reef rock," he added.
