Thought this might be of interest to some.
There is a photo here somewhere . . .
I was staying at the Renaissance and was wondering what the emergency vehicles were waiting for; I suspected it might have been some kind of emergency. In the end, a perfectly normal landing was flown, although you can see that the flaps do indeed appear to be stuck in Config 2.
A good job by the crew and as ever, the LHR emergency crews showed the professionalism expected of them.
