All we are doing here is plotting a V-G diagram. I think you will agree that Vd is the end of the diagram and the start of the structural failure zone?
Second, while you can graph a few V speeds onto a generic V-G diagram and make it work for students, but hardly good enough for engineering data. There are lots more to a V-G diagram than those 3 speeds.
Agreed. But the diagrams offered above can hardly be considered "fake". It is constructed directly from the Boeing Type Certificate Data Sheet.
No one is claiming an aircraft breaks apart 1 knot over Vd. Keith is the only one making that claim in which he claims comes from some conspiracy site. But for some reason he does not want to source it.
Perhaps this is why.

Such a claim was never made.
There are a number of other factors to the right side-bird strike protection, flight control characteristics (aileron reversal, hydraulic control limits, wing bending) and flight test design.
Exactly.
