YCKT
Wouldn't mind betting the 172 was asked to keep the speed up due following traffic....but instead dangled the flaps all the way to 40 on final and dragged it in at 60kts...as no doubt taught to do. Personally I have come in flapless and got outa everyones way...but that's just me....there are other flap settings besides full down.
If it was rwy 15 at CNS with the usual trades blowing ground speed might have been as low as 45kts...that hardly what I'd call playing the game with a Dash and 737 following you down finals.
If going around from a full flap approach caused an incident then the person needs more training.
Just my rambling thoughts.
