Many of us have experienced the missed approach, and also the pilot retiring after today's flight. The two don't necessarily coincide.

There are many "near miss" incidents at airports every year including runway incursions. Often the pilot sees something the ATC hadn't noted, such as a plane below being slow clearing the runway, and aborts the landing. Sometimes the captain says that's what happened, other times there's just an announcement that "we're going to go around again."
