== blurred memory of the pilot + doubts == 

 There is some edit warring over a text regarding the blurred memory of the pilot and thus the value of his debriefings... The statements are vague ("according to related sources" and "leading to critics believing") and I couldn't find anything in the cited source (here, searched for "blur", "critics"). Can someone help with getting the correct sources, so we can determine if this is all usable for wikipedia, and (if it is to stay) make the statement less vague and suggestive?
