Foam, Jet Jockey A4, tons of foam.
Tell me how is it possible the PILOTS did not know about the fire?
Don't think anyone has suggested that they didn't? The entire thread has devolved into a two sided discussion on whether the captain should have ordered an evacuation immediately and ignored any outside professional advice, if it was available, or made a decision based on all information available, with both sides basing their argument on pure speculation and no, or very few, relevant facts. The thread has become a hamster wheel and I am jumping off!.
