Kudos to the crew for handling ghe emergency and getting everyone on the ground and evacuated safely! My question is given the crew reported smoke in the cockpit then cabin would it have been prudent to cut the bleeds before the smoke started to prevent it from occurring in the first place? In other words engine damage/fire should have a memory item BLEEDS/PACKS OFF. My thinking on this was if we are having to contend with APUs dumping smelly cancer socks into the air system and we turn the packs/bleeds off right away why no do the same to lfor eng damage/fire? Even for perhaps engine surging.
