Subsonic only, and with lots of crazy adaptation to fit the crazy laws, like changing the aircraft registration number on each flight.<p>But all those pictures I saw were advertising drawings: <a href="https://www.heritageconcorde.com/braniff-airways-concorde-operations" rel="nofollow">https://www.heritageconcorde.com/braniff-airways-concorde-op...</a>
