Yeah, this "emergency" struck me as not being an emergency. The pilot landed safely during a low traffic portion of the evening. Most accidents are a confluence of small minor errors that idividually would not have been a problem but when taken together produce the confusion that leads to mistakes. This could have been one of those factors, but it wasn't so no harm no fowl. Give the controller a stern talking to and review the scheduling to see if the manager who scheduled him deserves some blame and call it good.
