That explains it then. Tuesday morning I was woken by an horrendous noise. I live about 5nm on the localiser for R23 and passing aircraft are not usually noticed.
But Tuesday a 747 (must have been TF-ATC) was banking sharply at about 1000' heading back across the localiser at what sounded like fullish power. I watched it track back towards lining up for R23, and once it had done that it again aborted, this time banking right. I never saw/heard it again.
Even the wife was concerned!
