The worrying thing is that the powers that be in light aviation seem to find the "land after" unacceptable and issue a go around order at the drop of a hat, it seems that the only place that I now regularly get a land after clearance is at Gatwick.
Well technically it's not a clearance; Biggin offer them fairly regularly - I've had two myself there that I can remember off the top of my head. On one occasion when waiting at the hold, I observed an American (going by his accent) on short final in a jet being given a land after and he had absolutely no idea what the controller meant. He flew down the runway asking 'land after what?' or words to that effect. Eventually when the other traffic had exited the runway he was cleared to land and then he touched down. He was then asked to contact the tower once he had shut down! Maybe that partially explains the reluctance to use it at other ATC fields?
