Rolls Royce has really turned things around in the last 20 years with the RB 211. It was a real problem laiden power plant. On one of my trips across the pond, the RR CEO came up to the cockpit for a visit (oh, the good old days!) He asked me what I thought of the RB 211. I told him that I had no problems with it. He replied, only half jokingly "If I type up your statement, would you be willing to sign it?" Later I had big problems with one..scattering fan blades over the southern half of New Mexico.
