Thanks luoto for the amended link.
Well if I was the Dublin ATC head receiving such a report from BA, I would just copy and paste the audio file and write : "contact us if you have any further questions" .
But I bet you a pint of Guinness that no report was written in the end , it was just like a kid bravado after the other crew comments on the R/T to get the final word .
It is also apparently his own error to stop monitoring the frequency, if I get it correctly.
Anyway , kuddos to the girl for remaining quiet and professional all the way . I do not think I would have remained myself that polite until the end...
