It does make you speculate about what was going on in both of the PA-28s mentioned piling in (or nearly so) at Rochester. On each occasion it must have looked well wrong. We don't know all the facts, but it's tempting to say that the instructor should have commanded the go around, or even taken over if need be (so tempting indeed that I've just said it).
It may be that people become too proud to go around, or even too worried about the bill. No one would ever admit this, though. I suspect more of the former: surely no-one really thinks about how much it's costing them when on short final?
