Concorde was a royal pain in the behind, with it's cruise climb - get out of my way mentality. It was just another a/c that paid the same route charges as similar types. Very sad to see it stop flying but very glad to see the back of it from an Air Traffic perspective, some of the biz jets are doing 0.9 or more these days so in the enroute not oceanic airspace they are going almost as quick.
