This Airline Operated The Rarest Boeing 767s In The World

A little more than 2% of all Boeing 767s built have been built with Rolls-Royce RB211 engines. Most of those were ordered by British Airways, and none appear to be operational today. The tale of the RB211 is a curious one, as the engine proved very unpopular when it was adapted for the Boeing 767. Since then, Rolls-Royce has managed to develop it into one of the world’s most successful widebody engines.
