Rolls-Royce RB211

I was reading the BBC story about Turing's Bombe beating out Concorde in a UK mechanical engineers poll: http://www.bbc.co.uk/news/uk-england-beds-bucks-herts-295126...

And therein found a mention to the RB211 with the following mention:

    The Rolls Royce RB211 engine received 11% of the vote.

    It was developed in the late 1960s but cost miscalculations led to the company
    going bust in 1971. 

The Wikipedia has the best summary on this period that I could find, but I also thought that this event might be of interest to people on HN as it combines both a story of engineering as well as the story of a business going through massive change: http://aerosociety.com/Events/Event-List/1754/The-History-of...
