I think you missed a key point though
No Pistonprop I didn't. The OP didn't answer his own question he stated what the Captains reason for the go-around had been which wasn't an explanation was it? As many have been keen to point out there can be numerous reasons for another aircraft to be on the runway and most are fairly routine but as a fellow go-around survivor (I haven't written my book yet) I can confirm that to someone unfamiliar with air operations the sudden change from gentle descent to unexpected acceleration can raise an eyebrow.
My point is that it reeks of elitism when people prowl forums which are clearly not exclusively aimed at professionals (and probably exist to discourage amateurs from those pages) and then leap on questions with faux outrage at their naivety.
