That is the image you paint of him with your attacks upon his reputation. Easy to attack a dead man, isn't it Asmodeus..
Donaldson discredited himself with his inept "analysis" of witness reports.
Your assertion that Commander Donaldson is "inept" in his analysis is without merit, as you have not proven yourself an expert in anything. You CLAIM to be an expert, but refuse to explain why we should believe that. And for you to say that Commander Donaldson has "discredited" himself is a furthur indication that you have no sense of shame..
He was unqualified by training and experience for the roles he attempted to assume of [1] expertly interviewing the witnesses, and [2] expertly analyzing the witness reports.
He has performed triangulations of the witness reports, along with analysis of the trajectories of what they saw. You haven't performed ANY analysis in any true sense, but have simply disparaged the witnesses.
His experience in aviation accident investigations gives him the ability to analyze witness reports in relation to that accident.
You demonstrate no such experience, thus your proclamations of expertise are highly questionable. The witness statements speak for themselves, and you apparently have a problem with what those statements say.
