I can see the plane being sturdy enough to absorb wave action by moving with the waves. However, Emily describing wreckage in the same place as the Bevignton Object suggests the plane, or parts of the plane, did not move for years. The location of the Bevington object and where Emily saw plane wreckage is near where the waves break. Based on that, it seems the parts there years later might be something very sturdy, like an engine,(Emily described something like rust, not shiny) possibly with parts of the nacelle including the landing gear. I don’t see the landing gear staying on the reef long by itself due the surface area of the tire unless it was hung up, secured or somehow connected to a bigger piece.
The Glickman Debris Field also suggests some break up. However, if the “debris field” is from the plane, that debris could be from larger pieces, or most of the plane, tumbling down the underwater terrain after it sank, because the “debris” appears to be somewhat localized. The debris pieces are so close together, they could be from a large piece that disintegrated in place, underwater, with pieces migrating downhill in a crevice after corroding.
Taking the Bevington object, Emily’s story, the Debris Field and the Sonar Anomaly all together, I think the plane broke into big pieces on the reef by getting blown offshore by the wind and then pushed back into the reef edge by the current and waves a few times. Enough back and forth to break it and/or open enough holes to allow most of it or big pieces to sink just south of where it initially went over. The heavier more sturdy pieces staying in the dynamic reef edge area long enough for Emily and her father to see them at neap tide.
I don’t think a person made the first fracture in 2-2-V-1 in an attempt to remove it. I also have some difficulty seeing someone popping the bulk of the rivet heads off and separating the skin from the stringers without deforming the skin more. However, I can see the fracture from fatigue being made by someone and some of the rivets or stringers being removed due to the tool marks.
2-2-V-1 by itself would not float. Although possible, getting 2-2-V-1 to the point near the landing channel by currents alone pushing it along the reef does not seem likely to me by looking at the debris pattern from the NC. The fatigue fracture, tool marks and its found location, suggest to me that 2-2-V-1 was moved closer to the channel by someone and later abandoned. I don’t see it as being used for other purposes for long due to the awkwardness of the fractures
