I disagree with the assertions of a non-stabilized approach. Once more, we do not have enough information to make that judgement.
For example, on a visual approach at a steady 1000 fpm descent, this could be a perfectly "stable" and acceptable approach. If the runway is long enough, a safe landing could be made. Even if on an ILS, if the "4 white" PAPI equated to less than a half-dot deviation above the G/S, the approach could be considered stable, and a safe landing could be made after continuing at the 1000 fpm descent rate. As noted by a few above, there are airports where a 1000 fpm descent on short final is routine.
Still, I would not question anyone if he decided to go around in the situation. As for Lord Spandex Masher's FSO, he needs a different job if he is questioning a pilot's decision to go around ANY time!
