I remember that crash and I knew the Captain from Acklington in the 60's. I was not, however, involved in the BOI and I have never read the full BOI; only the Flight Safety precis. I am aware of certain "sensitive" facets in respect of matters pertaining to the Accident and subsequent investigation. I do not think it is correct to air such matters on this forum but (if you wish) PM me and I will reply with what I remember. I suspect, however, that you are already aware of those matters.
