Not wishing to be dragged into the specifics of this event, I was merely pointing out that these situations are indeed emergencies... and can never be considered otherwise. As to the BA incident you describe.. I would never in a million years consider a transatlantic crossing on 3 engines on a four-engined aeroplane having had a fire warning, successfully extinguished or otherwise.. the only safest option on that occasion would have been to land at the nearest suitable airport.. to do otherwise was in my opinion madness. I do not work for BA so I cannot comment futher.
