I guess he has four engines and ETOPS is a relative thing, but a few minutes into it he probably thought he wasn't on fire because he was still alive and made his way back to a place he knew he had service. Staring over three hours at a fire indication is an acquired taste but they are hard to get rid off if the sensors are activated. Know nothing about Airbuses, but I assume part of his checklist is turning the fans off. I would have done the same thing. Would hate to have to explain why I went ETOPS with a fire indication, the next day at the chief pilot's office.
