> The recollections of an 88 year old person about an event 60 years ago are simply not credible.
My experience with aging family members is that their memory of old events tends to improve as their short-term memory seems to get worse. I've had family memebers not remember where an object is, and from their nursing home bed, when asked about "what happened to ___?" reply with remarkable accuracy - to the point we were able to find several family heirlooms (photos from WWII that were lost in the 1960s, an old service rifle, old writings, paintings) right where they said it was. I wonder if perhaps that is the case here.
I have had aging family members who remembered things that cannot possibly have happened. Going beyond anecdotes, false memories are a well known and empirically studied effect: https://en.wikipedia.org/wiki/False_memory
