The RB211 is a fantasic engine in my experience. A few years ago a squad of seagulls few through one just after take off. We were airbourne for around 45 mins before landing to get down to max landing weight. From the flight deck the engine instruments were normal and the engine was responding normally. The resulting boroscope inspection showed that the rear section of the engine was badly enough damaged that an engine change was required. Give me an RB211 any time.
