Hello Terry,
I am with you as far as a fairy tale goes, this person has twisted the data to suite his own outcome. There is no way to know if the doppler on a signal is from mid path, end path or from local contributions. Considering the RCS (Radio Cross Section) of an aircraft at HF it takes quite a bit of transmitted RF to get a result (experience from my Jindalee employment). Then to factor out the background sea state doppler, well that takes quite a bit to do. Plus by what propagation mode was this measurement made, if this was F layer then the plane was well below any ionospheric layer and would not be involved in the signal path at all.... seems the basic mechanics of the signal path are being misrepresented.
Yes a fairy tale where the truth is being played with for bad reasons.
