I think this might
demonstrate the incident (apologies for the annoying advert) in a much clearer manner and having seen it and also the comments that this very senior, very experienced pilot had admitted that this was not the first error during his command then I hate to say this but his options were VERY limited and like others before him (in different circumstances) ... far better to gracefully step down as opposed to facing the alternative options.
This has done a degree of harm to this person's no doubt well deserved reputation, possible career but my God, they were seconds away from making an awful skidmark on that pristine condition runway!
