There is considerable discrepancy in the reporting of where & when this engine problem occurred. Either it was 1 hour after takeoff or immediately. In the former case they might have over flown Accra to return to Lagos, a more friendly place, but perhaps the crew had never been there and knew Lagos. The reports above are seeming to suggest the fire occurred on the ground. There are too many unclear details. Someone needs to beat the drums louder & slower.
