I've listened to the tape 3 times now and not once did I hear any reference to fuel emergency. Maybe the crew declared a fuel emergency before, in which case, no problem. But I hope the crew listen to the tape and take on board the assistance that was trying to be offered and appreciate the increased workload that was handled very professionally by the controller. No doubt the controller was also co-ordinating with colleagues around to facilitate the American pilots safe and expeditious landing, which, unfortunately the tape doesn't record. Whoever the controller was, a job well done, in difficult circumstances.
