Okay, I'll bite - how do you form the view of it being overweight?
I am sure FDX has checks/x-checks, ticks in boxes, etc. to ensure that ALL structural limitations are not exceeded for all phases of flight, including MLW. Reputable trash-haulers ensure the correct mass is loaded into the correct position. (That is not to say, that on occasion, the system is let down by the humans). I do not work for FDX (hence I do not know their loading system) but I would need a lot of convincing to change my opinion that the flight was anything but within limitations.
With the AQP/FIDS systems installed on the MD11, it would be a very brave pilot (or cowboy) that would intentionally land overweight; the soon-to-be arranged "fireside chat" would definitely get interesting.
I'll entertain quite a few theories and rumours with respect to this accident, but I'll pass on it being an overweight landing (unless you think a >1.0g IVTG counts as being "overweight").
