Thanks for the info BizJetJock.
4 knots isn't much by itself, but is still extra airspeed. A few knots incorporated into the AFM derived Vref, a few more for gusts, a few for the home folks and pretty soon you're talking too much airspeed to to touch the mains down without touching the nose too. Add the effect of a pilot pushing the nose down and forcing the airplane onto the runway due to diminishing runway remaining and you have a scenario similar to what occurred in ASE. In hindsight a diversion to RIL or GJT and an hour ride with Mountain Limo don't look so inconvenient now...
Like I said, it will be interesting to see the FDR traces when or if they become publicly viewable.
