The C560 will use up lots and lots of runway when your fast and land long on a wet runway. The AFM/OM states that for every knot over ref the landing roll will increase at least 2%. Landing distance is based at being at Vref speed, 50' over the threshhold and power to idle. If your 15-20 knots over ref and land long, you don't have a chance to get it stopped in 2900'. The C560 is a great airplane, I've been there and done that many times, but it can't do what it's not made to do. Tragic outcome. My thoughts and prayers to the familys.
