So what is the real issue? Reading between the lines there are some clear politics at work. Its all about being safe - if there was no accident then there is nothing (at face value) for the CAA to be involved with. If the air traffic controller thought that there was some risk to the pilot, perhaps from how he appeared to be flying, or from the crosswind exceeding the published limits for a particular aircraft type (and the air traffic controller knowing the limits for that type, perhaps through personal experience) then the air traffic controller was in my opinion right to work on the side of caution and having the fire services on standby was a positive move. They were not needed and will no doubt treat the whole incident as some "practice" which ensures they remain effective and ready for a real incident.
The pilots ego may be bruised, so what?.... at the end of the day the rescue services were not needed. if they had been then they would have been on scene in seconds rather than minutes. Perhaps even the difference between life or death.
It all sounds a little childish.
