eal401,
I am assuming that you are not a pilot (at least on big stuff). Landing long means not touching down in the touchdown zone, and therefore having a lot less runway to use after touchdown. Very poor airmanship especially on a wet runway.
Any ATCers at LGW know who the light turboprop was coming in last night. I mistook his callsign for a Kestrel one and assumed early on that we were following a normal arrival. However having spotted his low level arrival (do CDAs count for turboprops?), we started to be a bit more wary and already started to slown down before asked by ATC (the joys of TCAS!). I was very impressed at the coolness of the tower controller, which most definately saved a go-around!
