Haven't spoken to the Capt, but I know him pretty well.
All of us would have done the same, great intentions during the diversion to do the right thing at all times. Apply professional SOP's throughout and he just got unlucky to be the one who clipped the light. Any of us could have been that person and I say that none of us here or in the company could say with certainty that we would have been guaranteed that this could not have happened to us.
Don't worry about brake temps if there is a turn off around 3000m along the runway to exit when on a diversion transit stopover (weight dependant). The thought of ever having to do a 180 turn in the beast will always be considered a threat by most from now on. 55m minimum distance required to test pilot turn it, GL at an unusual airfield doing a procedure that you probably did years ago during the transition.
