Precisely, morno. It's an unremarkable set of circumstances, explicable on the basis of 'Basic Aeronautical Knowledge' informed by a little bit of experience.
It seems to me that a hypothetical prosecution on the basis that groundspeed minus forecast wind = a number bigger than the aircraft's VNE 'proves' an aircraft was operated in excess of VNE would, at best, be based on very poor Basic Aeronautical Knowledge.
(Yes, Duck: Some of the things said by Senator Macdonald in recent hearings about what she has been told about the activities of an investigator would, if true, be very concerning.)
