Every tail skid and/or tail contact incident that I am familiar with (lots, btw) regarding transport category aircraft are related to pilot error, and most are the result of over rotation on takeoff. No relation to where the CG happened to be, nor what factors produced said CG location.
I do know that it doesn’t take much weight movement (location) to drastically change the CG of large aircraft with major results. For instance – If you take all the fuel out of a DC-8 you’d better tie a cement block to the nose or put the tail post (long pole) in place on the rear skid. Otherwise, 3 grown men can walk from the front of the aircraft to the rear and put it on its tail.
Very weird feeling.
