Awaiting the arrival of 411A
You called?
The concerned Captain demonstrated, at a quite critical time, an unusual ability to 'think outside the box' (by selecting a lower flap setting), something many pilots are unable to do, so...his re-hiring is, in my opinion, a good thing.
I would futher suggest that he be assigned to the (now First Officer) who was in command of the airplane in the Caribbean, where it was apparently considered a waste of time to actually use the entire length of the runway for takeoff.
Perhaps in this way the BA operation can actually be improved.
