surprisingly, very little information available
I am a MEM-based FDX MD10/11 first officer, and I have only heard what is posted here.
Some nasty cross-winds that morning, but I haven't researched if they coincided with the accident.
Purely speculation but all the hard landings we've suffered in the past resulted in either a shear of the main strut or spar failure. To me this one looks like an overcenter strut probem - folded up when they started their turn off the runway, perhaps? If the main strut had failed they would have ended up off the runway much earlier....
I'll keep you all posted with what I can.
