I'd be curious if one or both of this crew had flown into SFS, how much and how recently. With the previous over-run and the "reputation" about SFS and its (short??) runway, maybe some pilots worry to much about getting it down after a little "float" and create a problem that isn't/wasn't there. We will just have to wait and hear what the "truth" (according to the NTSB and Fedex ) and learn from it as we always do (should ) .
