In 2006, during a ground run at LAX, GE CF6 in the number one position let go on an American Airlines 767. Two taxiways were closed while bits of disc were retrieved. Attached are some photos, one of which shows half a disc sticking out of an engine. In fact, the disc belongs to the other engine - it's passed through the centre wing box and embedded itself. Undoubtedly, this would have brought down the aircraft had this happened in service. The rear fuselage and port inboard flaps were toasted as combustor exit gases escaped and hit the airframe, which has been written off.
