Those enamored of the Bevington Object may take some solace from the attached frame, which comes from the very up-hill-most part of the 2010 HD video. I don't know if the layout of the components of a second landing gear assembly as I see them bears any relationship to either the original or modified interpretations entertained by TIGHAR. The cylinder stretches out to the right from the Y-shaped support braces. I will note that the tire, although quite flat and shredded, appears to be the same pinkish color as the tire in the landing gear assembly identified further down-slope (second photo, at time 13:37:16, frame 06).
Question: if this is a second landing gear assembly, is it really possible that it could also be the Bevington Object? If so, it would mean that the aircraft first sank 800 feet to its present position and then, sometime later, the Bevington Object was washed off the reef and just happened to land on top of the previously deposited debris field. After thinking about this for a day, it seems to me that the probability would be reasonably good if the "arroyo" containing this debris field extended upward pretty much all the way to the edge of the reef.
EDIT: I have substituted a much better frame showing all the components (time 13:37:16, frame 15).
