I wouldn't exactly call the Concorde a success. From a technical standpoint yes, it was a fantastic machine, with a lot of industry firsts and important technological advancements that has filtered down into different areas, but commercially it was a total failure.
That being said, this is a technical forum, and I had the fortune of flying with a top Concorde trainer the other month which has made me rather a fan. He mentioned that the super cruise was the main thing they had the Russians beat on - the TU-144 needed reheats which cut the range dramatically.
